Lactose is a type of sugar that is found in dairy products. The bacteria make a specific enzyme known as lactase. The lactase enzyme is what assists in breaking down lactose sugars. The resulting compound is known as lactic acid. Lactobacillus Rhamnosus is a bacterium species that is often included in scientific studies. This bacterium is part of the Lactobacillus family and plays a role in several digestive functions.
They indeed observed clear differences in the transcriptional response to exponentially growing or stationary phase bacteria, and between viable and heat-killed stationary bacteria. In addition, ex vivo and in vitro models such as the porcine small intestinal epithelial cell line (IPEC-J2) appear to be good models All CBD for Pets for the study of innate immune responses to probiotics . We also demonstrated that metabolites produced by L. Gallinarum could suppress CRC cell viability through inducing apoptosis. Using metabolomic analysis, we found that L. Gallinarum could produce L-tryptophan and convert L-tryptophan to its catabolites.
To 100 of sterile medium an appropriate amount of potentially toxic component and then 1% (1 ) of inoculum was introduced. The cultures were incubated at 38°C with shaking at 120 rpm on a rotary shaker . The samples were collected in triplication while the culture was being grown. Lead to the diauxic growth on glucose and citrate. For more information and the latest research on probiotics, please visit the Probiotic Professionalspages. This is one of the first studies to show an association between probiotic use and postnatal depression.
However, the role of QS in pathogen exclusion is difficult to investigate since the AI-2 synthase LuxS also interferes with the cell metabolism. Indeed, a luxS knock-out mutant of LGG was shown to have numerous pleiotropic effects, which could not be complemented by exogenous addition of synthetic AI-2 molecules . It remains to be investigated whether AI-2 or other QS systems play a role as a probiotic mechanism for LGG. As mentioned before, Msp1/p75 and Msp2/p40 are not unique for LGG.
Due to the promising results seen and protective effects of L. Rhamnosus HN001, follow up studies were conducted. These results indicate that the probiotic combination may help to rebalance the vaginal microbiome and improve symptoms of bacterial vaginosis (Russo et al., 2019).
Also, the German trial had more infants with older siblings, which could be a potential cofounder . In addition, it seems that different probiotic products have been used for these studies, so that also differences in probiotic formulation, and for instance pili presence, cannot be ruled out. LGG was reported to produce autoinducer-2 (AI-2), which is suggested to be an important interspecies QS molecules, produced by both Gram-positive and Gram-negative bacteria .
Combination of Annexin V-PE and 7-AAD staining distinguished early apoptotic cells (Annexin V+, 7-AAD−) and late apoptotic cells (Annexin V+, 7-AAD+). For cell cycle analysis, cells treated with 10% LGCS, ECCS or BHI for 1 day were fixed and stained with 50 µg/mL propidium iodide . Cell cycle of all stained cells were analysed using FASAria cell sorter . Inhibition of enteric bacteria and enhancement of barrier function by probiotic bacteria. Schematic representation of the crosstalk between probiotic bacteria and the intestinal mucosa.
This gene encodes a membrane protein that facilitates the ligation of the D-alanyl carrier protein with D-alanine . This mutant showed a strongly reduced interaction with TLR2-6 and a lower induction of IL-8 mRNA in the Caco-2 cell line compared to wild type, further substantiating a key role for LGG LTA in promoting more pro- inflammatory responses . Furthermore, the dltD mutant significantly improved DSS- induced colitis in treated mice compared to buffer control, while the wild type strain showed actually detrimental effects in that model . Interestingly, similar effects were observed with LTA mutants in other lactobacilli . Complete removal of LTA in Lactobacillus acidophilus NCFM or a shift from mainly D-alanine to glucosyl substitutions in Lactobacillus plantarum NCIMB8826 also resulted in strains capable of more efficiently alleviating inflammation. This shows that LTA is not an LGG-specific effector molecule, but that it is an important molecule in understanding Lactobacillus-host interactions and is a crucial factor to take into account when investigating anti-inflammatory effects.
We then performed functional investigation of ILA in CRC cell growth in vitro and in CRC tumourigenesis in vivo. As shown in figure 7E, cell viability of CRC cells but not normal colonic epithelial cell NCM460 was substantially reduced when exposing to ILA at a concentration comparable to that of LGCS. Consistent with the effect of LGCS, ILA-treated CRC cells showed an increase Just Delta 10 Gummies in apoptosis . For in vivo experiments, gavage of ILA (20 mg/kg) into ApcMin/+ mice significantly reduced tumour number and tumour size . The amount of cells with positive TUNEL staining was also increased in ILA-treated tumour tissues, but not in adjacent normal tissues . Moreover, we have performed additional experiments to investigate if antagonising ILA could abrogate L.
Significance Of This Study
Women received either a combination of L. Rhamnosus HN001, Lactobacillus acidophilus La-14® (5 billion CFU/day) and lactoferrin or placebo for 15 days. Vaginal swabs were collected at baseline and day 15. Acidophilus levels were detected by day 15 in the probiotic group. Baseline Nugent scores were 5.09 and 5.10 in the probiotic and placebo group respectively.
Both appear very useful to describe practically the non-linear dependence of the rate coefficient for growth, and the lag time, which normally prevents the use of the Arrhenius equation. Clinical trials are, by their nature, highly controlled and always exclude some patients, thus work is required to test the use of probiotic products in routine clinical practice. It is important to show that the products can be easily acquired and successfully delivered to patients in the healthcare setting. Data are also needed to demonstrate that the probiotics are consumed in sufficient amounts, that any costs are outweighed by the savings, as well as demonstrating efficacy in reducing diarrhoea incidence.
We further identified that ILA, one of the L-tryptophan catabolites, was significantly increased in both LGCS and faecal samples of L. ILA inhibited CRC cell viability in vitro and suppressed intestinal tumour development in vivo. Casei has a strong tumour-suppressive effect on CRC cells by inhibiting the JNK signalling pathway.20 Interestingly, we also observed stronger tumor-suppressive effect of LGCS as compared with LCCS .

An adequate amount of these bacterium species in your gut can lead to several potential benefits. You are able to increase your intake of Lactobacillus Rhamnosus through the use of supplements or by turning to foods that contain the bacteria.

Targeting TLR9 with CpG or ODN has been a strategy for a number of clinical trials studying the effect on cancer treatment, allergy and infection diseases, reviewed in . It is important to note that TLR9 function in the intestinal epithelial layer is thought to be polarized as IECs respond differently to apical or basolateral exposure to CpG. As basolateral TLR9 activation signals activation of the NF-κB pathway, apical TLR9 stimulation seems to prevent NF-κB activation.
Probiotics In The Prevention Of Antibiotic
Seven heat-stable peptides with antibacterial activity against enteroaggregative E. Coli strain EAEC 042, Salmonella Typhi, and Staphylococcus aureus were identified in LGG culture medium . Unfortunately, these peptides have not yet been identified, to the best of our knowledge. Of note, the genome sequence of LGG encodes several bacteriocin-related genes . Another perhaps more elegant way to investigate the immunomodulatory effects of LGG is by studying its capacity to ameliorate humoral responses to vaccines when applied as an adjuvant. One study showed that the immunogenicity of an oral rotavirus vaccine was significantly ameliorated when mixed with 5×1010 CFU of LGG .

A larger single-blind, randomized, placebo-controlled trial focused on children (3 × 109 CFU daily, dissolved in water or milk) and could show a significant difference between the treated and the control groups only after three weeks . The mechanism of clearing of this vancomycin-resistant enterococci remains to be explored, but the SpaCBA pili of LGG share some sequence identity (30-40%) with the pili of Enterococcus faecalis and Enterococcus faecium . Clearly, experiments with non-GMO pili deficient variants of LGG would be highly interesting to study their role in the gastro-intestinal and pathogen exclusion effects of LGG. In 2002, Yan and Polk showed that LGG promotes the survival of intestinal epithelial cells by preventing cytokine-induced apoptosis through blocking of p38 MAP kinase.
The Safety Implications Of Probiotic Use In Patients At Risk Of Antibiotic
In this study, we demonstrated for the first time that oral administration of L. Gallinarum reduced intestinal tumour number and size in ApcMin/+ mice and confirmed in AOM/DSS-induced CRC mouse model, indicating that L. Gallinarum suppresses CRC tumourigenesis in both male and female mice.
Cell Viability Assay
Indeed, infants acquire more oral tolerance when hydrolyzed casein formula was administered in combination with LGG (107 CFU/ 100 mL) than with the formula alone . In milk-hypersensitive adults, LGG (2.6×108 CFU daily in milk) has been shown to reduce the immunoinflammatory response by reducing the expression of specific receptors such as the complement receptors CR1 and CR3 . Apart from EPS, other genes and molecules play a role as factors that promote the adaptation of LGG to the human host and gastro-intestinal tract in particular. For instance, an elegant study combining transcriptomics and proteomics in LGG identified putative adaptation factors involved in the bile stress response of LGG. Among the identified functions were general stress responses as well as cell envelope-related functions, including pathways affecting fatty acid composition, cell surface charge, and thickness of the EPS layer . Our recent recombinase-based in vivo expression technology (R-IVET) experiment, similar as in L.
For instance, people with IBS may have fewer Lactobacillus and Bifidobacterium bacteria but more potentially harmful Clostridium, Streptococcus, and E. Rhamnosus don’t typically include it in the ingredients list. Hundreds of studies support the benefits of L. Probiotics are live microorganisms that can offer health benefits when consumed .
New-borns also took the strain directly from birth up to two years. The researchers found the strain was well tolerated with no significant differences between the probiotic and control groups (Dekker J et al., 2009). Mack DR, Ahrne S, Hyde L, Wei S, Hollingsworth MA. Extracellular MUC3 mucin secretion follows adherence of Lactobacillus strains to intestinal epithelial cells in vitro. One of the widely studied key features of LGG is its strong adhesive capacity, which has been documented in vitro but also in vivo in humans.
Regarding growth conditions, it has the ability to grow between 15-40°C at a pH level of 4.5 to 6.4 (Valik et al., 2008). Clinical experiments with Lactobacillus rhamnosus GG observed a resistance to respiratory and gastrointestinal infections also fever decrement, also healing effects to atopic eczema (Mattila-Sandholm et al., 1999). As some properties & benefits of probiotics may be strain-specific, this database provides even more detailed information at strain level.Read more about the strains that we have included from this genus below. Rhamnosus HN001 supplementation in the later part of pregnancy and direct supplementation to the infant from birth for two years was able to reduce the risk of eczema up to the age of six.
It has been trialled extensively in pregnant women showing safety and efficacy. Rhamnosus HN001 is one of the few strains to demonstrate abilities supporting mental well-being, vaginal health and immunity. Cells were plated on 6-well plates 24 hours prior to treatment, and cultured in medium containing 10% LGCS, E. CRC patient-derived organoids were cultured on 6-well plates, and 10% LGCS, ECCS or BHI was added to Matrigel and growth medium. After 5 days of treatment, cells and organoids were digested in 0.25% trypsin-EDTA (Gibco‐Invitrogen, Grand Island, New York, USA) and TrypLE, respectively. For apoptosis assay, the proportion of apoptotic cells was evaluated by dual staining with Annexin V-PE and 7-aminoactinomycin D (7-AAD) .
Rhamnosus is sometimes added to dairy products — such as yogurts and milk — to boost their probiotic content and to cheeses to aid the ripening process. Rhamnosus GR1 strain — given either orally or intravaginally — was particularly effective at killing harmful bacteria in the urinary tract . SCFAs are made when your healthy gut bacteria ferment fiber inside your digestive tract. They are a source of nourishment for the cells lining your colon . The project will include transformation of the gained scientific knowledge to a design of innovations in technology and novel products with an acceptable safety level and improved sensory quality.
ID35 isolated form LGG genome even seems to be beneficial in allergy prevention in an ovalbumin-sensitized mouse model, by inducing the TH1-response and suppressing ovalbumine-specific IgE production . Moreover, a study using peripheral blood mononuclear cells from allergic patients showed that LGG as well as its genomic DNA can modulate the TH1/TH2 response to specific allergens dose-specifically. More than 50% of the effect of LGG could be explained by the effect of the genomic DNA, as stated by the authors .
However, the reviews also note that infections are very rare and are not reported in most trials of probiotics, even those studying immunocompromised groups, such as HIV and neonates. There are two recent papers evaluating the evidence on the prevention of CDAD [Parkes et al. 2009; Tung et al. 2009]. Parkes and colleagues reviewed five studies, three testing mixtures of bacteria and two examining S. The results were varied with one mixture [Plummer et al. 2004] and neither S.
Rhamnosus is great for your digestive health. In addition, taking a probiotic during and after antibiotic use can help restore your healthy gut bacteria, since antibiotics often kill them alongside harmful bacteria. Rhamnosus is available as a probiotic supplement and often added to yogurts, cheeses, milk, and other dairy products to boost probiotic content. One of the most well-studied friendly bacteria is Lactobacillus rhamnosus (L. rhamnosus), which is available as a dietary supplement and added to a variety of foods, such as dairy products. Some studies show that it is very helpful for a vaginal infection such as a vaginal yeast infection or bacterial vaginosis, and also for a urinary tract infection . It is estimated that 8-24% of pregnant women may develop GDM (Farrar D et al., 2016).
It has been found that the diversity and number of Lactobacillus bacteria, along with other types, arefewer in people with diagnosed irritable bowel syndrome. Rhamnosus bacterium species, in particular, seems to be very effective in relieving the symptoms a person may experience due to irritable bowel syndrome. CRC organoids derived from 2 patients were obtained from Princess Margaret Living Biobank , and embedded into Matrigel . Culture medium was changed every 2 days.

Growth on medium containing glucose+citrate demonstrated simultaneous utilization of carbon sources. Rhamnosus did not grow in a medium containing acetate and also did not co-metabolize it with glucose. Maximum specific growth rate was found to increase in the case of simultaneous utilization of glucose+citrate (0.38 h–1) as compared to glucose as the sole carbon source (0.28 h–1). The yields of diacetyl were also found to increase for glucose + pyruvate and glucose + citrate (0.10 and 0.05 g g–1 of glucose, respectively) as compared to glucose alone (0.01 g g–1 of glucose). The productivity of diacetyl on medium containing glucose and citrate was double that of a medium containing only citrate, although the yields were comparable. Generally, slightly higher variability among R 2 values was observed within quadruplicates at lower values of temperature and a w .
Rhamnosus HN001 was able to enhance phagocytic activity and NK cell activity in 52 healthy participants (Sheih Y et al., 2001). Rhamnosus HN001 has also been demonstrated in murine studies (Gill et al., 2001) (Gill et al., 2000). Post labour, it’s been shown that vaginal and gut microbiomes may take time to return to ‘normal’ after birth. For the gut microbiome, it’s been estimated to take one month (Koren O et al., 2012). However, a study in the vaginal microbiome showed differences up to a year post birth (DiGiulio D et al., 2015) . However, instead of lactobacilli dominating, vaginal samples were abundant in many gut microbes suggesting migration during labour.
Rhamnosus HN001 supplementation may therefore be a useful intervention for pregnant women to lower their risk of GDM. Rhamnosus HN001 supplementation may be especially useful for woman at higher risk (Wickens K et al., 2017). Additionally, the number of women who scored above the cut off point for clinical anxiety was 50% lower in the probiotic group . Only 15.6% of women suffered with clinical anxiety in the probiotic group compared with 29.4% in the placebo group. Gallinarum culture-supernatant suppressed cell proliferation, and induced apoptosis in CRC cell lines and in organoids derived from patients with CRC. Gallinarum protects against intestinal tumourigenesis by producing protective metabolites that can promote apoptosis of CRC cells.
Rhamnosus and other probiotics , as such supplements may cause an infection. Rhamnosus species or these species combined with other probiotic bacteria. Rhamnosus strains may help prevent or relieve allergy symptoms by promoting the growth of friendly gut bacteria and suppressing the growth of harmful bacteria . In addition, studies link SCFAs to various benefits, including protection against colon cancer, weight loss, and lower blood sugar levels .
Each of the purified proteins was shown to activate the Akt signaling peptide, inhibit cytokine-induced IEC apoptosis and reduce tumor necrosis factor – induced epithelial damage. The proteins also promoted cell growth in human and mouse colon IECs and cultured mouse colon explants . Moreover, they were shown to protect the intestinal epithelial barrier function from hydrogen peroxide-induced damage through blocking of MAP kinases . As key adhesive components, the immunomodulatory capacity of the pili is also of high interest, although current data are very limited.
Gallinarum caused a significant overall compositional alteration of the gut metabolites as revealed by principal coordinate analysis . We found that metabolites including L-tryptophan, palmitic acid, 4-pyridoxic acid and gamma-L-glutamyl-L-glutamic Kann ich CBD versehentlich überdosieren? acid were significantly upregulated in mice after L. Gallinarum gavage as compared with control groups , which were also highly upregulated in LGCS . Among them, L-tryptophan was the most upregulated metabolite secreted by L.
This may increase the risk of intimate infections post pregnancy. There is also some evidence to suggest that post-natal depression may affect the quality of microbes present in breast milk which are passed to the new born (Browne P et al., 2019). Many pregnant women take supplements to support their babies’ health but may not realise that their own health can impact that of their baby’s both before and after birth.
Even though these effectors might not be unique for LGG, it seems that the sum of effectors in LGG is often beneficial for the host, while strains with similar MAMPS might show different results. Small variations in structure (pili, LTA, EPS, etc.), expression level or ratio can also have a large effect on the host response. However, it is also apparent that not all reported health effects of LGG are univocal. Successful administration appears to depend on the applied dose, growth phase, formulation, time of administration, duration of treatment, age and genetic background of study subjects, among other variables (Figure .
GTCGTT, than could be expected by their genomic GC content . Moreover, a potent ODN, TTTCGTTT named ID35, was identified in the LGG genome . The effect of chromosomal DNA of LGG was also tested in polarized IECs, where it was shown to diminish TNF-induced NF-κB activation and reduction of trans- epithelial resistance thus protecting the epithelial layer . The chromosomal DNA of LGG and derived ODNs were also shown to be strong in vivo inducers of murine B cell proliferation and were able to stimulate TH1 immunity in murine splenocyte cells .
In other conditions, LGG effects were better stratified. For instance, oral supplementation with LGG (6 × 109 CFU with human milk) has been shown to prevent enteric colonization by Candida species in preterm neonates in a randomized study , although the underlying mechanisms need to be explored. Furthermore, application of a commercial yoghurt with LGG to renal patients during 8 weeks has been shown to succeed in clearing vancomycin-resistant enterococci in all patients in an double-blind, randomized, placebo-controlled trial .
The difficulty in using such recommendations is that many probiotic strains are not readily available for use in healthcare institutions. There are few controls on the labelling and quality of probiotic bacteria, thus care is needed in ensuring that the products used contain only the claimed probiotic bacteria, in the claimed numbers, and will deliver viable bacteria to the lower gut. It should be noted that there are difficulties in linking infections to the specific probiotic strain, particularly if only phenotypic identification techniques are used. Ideally, genotypic methods should be used in order to identify the precise strain causing the infection and matching it to the probiotic strain. Lactobacillus bacteria are ubiquitous in the human diet and intestine and many strains are indistinguishable using only phenotypic techniques.
It will be very interesting to substantiate this indirect immunomodulatory role in human volunteers, e.g. by intervention studies with spontaneous pili mutants of LGG. Lacticaseibacillus rhamnosus GG is the most studied probiotic bacterium in the world. It is used as a probiotic supplement in many foods, including various dairy products. However, LGG grows poorly in milk, as it neither metabolizes the main milk carbohydrate lactose, nor degrades the major milk protein casein effectively.

The presence of pili should be a key question for future intervention studies with LGG. Even though many experimental in vitro data and experiments in animal models validate these mechanisms for probiotic strains in general and for LGG in specific, most published in vivo data in humans pay less attention to mechanisms of action. Nevertheless, we believe that for an optimized and more tailored application of probiotics, it is imperative to understand the mechanisms of interaction with the host in great detail. LGG is an interesting model probiotic strain, because of its wide use, its available genome sequence and the availability of numerous knock-out mutants that allow the study of gene-function relations [10-15]. In this review we aim to give an overview of the recent advances in the molecular knowledge on LGG-host interactions and try to provide a molecular framework for a better understanding of the health effects of LGG. PROBDEMO, a multi-centre European research project, began in 1996 with the aim of demonstrating that probiotic micro-organisms can positively effect human health in rigorously conducted human clinical studies.
The model is amodifiedArrhenius form, formulated from consideration of temperature-dependent chemical rate theory . This model form has not previously been evaluated for predicting temperature-dependent growth kinetics of bacteria. The model has two terms, namely, 1/Tand lnT, together with three coefficients. The model has fitted all available data without exception. This very good fit of the predictions of the model to primary data compared very well with the established and widely applied, empirical model form of Davey. Both models imply temperature-dependent Arrhenius parameters for the rate of microbial growth and survival.

Moreover, the neurochemical and behavioral effects were not found in vagotomized mice, identifying the vagus as a major modulatory constitutive communication pathway between the bacteria exposed to the gut and the brain. Subsequently, we found by mutational analysis of several predicted adhesins that the SpaCBA pili play a key role in adhesion to mucus, the Caco-2 intestinal epithelial cell line and promote biofilm formation . Of note, the LGG genome also encodes another pili gene cluster, spaDEF, but these pili do not seem to be expressed, at least not under the tested conditions .
Meyrand M, Guillot A, Goin M, Furlan S, Armalyte J, Kulakauskas S, Cortes-Perez NG, Thomas G, Chat S, Pechoux C. Et al.Surface proteome analysis of a natural isolate of Lactococcus lactis reveals the presence of pili able to bind human intestinal epithelial cells. The role of EPS in the interaction between LGG and the host remains largely unclear. Results obtained in our lab indicate that isolated galactose-rich EPS are not principal inducers of cytokines in the Caco-2 intestinal epithelial cell line .
On the other hand, as expected for the growth parameters, significantly lower variability was recorded among growth rates than among lag phase durations, as has been reported by various authors [21,28,. The estimated values of lag phase duration (λ, days) and maximum RGR (mm/d) for the strains under all of the experimental conditions are summarized in Supplementary Material Table CBD Gummies With THC S1. To further confirm L-tryptophan production by L. Gallinarum and its conversion into downstream metabolites, we performed high-throughput targeted L-tryptophan metabolic profiling using culture supernatant at the late-stage stationary phase of L. Gallinarum to ensure sufficient release and metabolic conversion of the metabolites , as well as faecal samples from ApcMin/+ mice .
Therefore, health and well-being during pregnancy and postnatally is vital for women. The microbiome undergoes many changes throughout pregnancy. This is unsurprising due to the hormonal, immunological and metabolic changes that are happening. In the first trimester, both gut and vaginal microbiomes are relatively stable. From trimester 1 to trimester 3, more pronounced changes are seen.
After 5 days of culture, Matrigel was removed to expose organoids by mechanical stress and/or TrypLE digestion (Sigma-Aldrich). Organoids were then collected for further experiments. La consommation de bonbons au CBD est-elle sûre ? The detailed information about these two patients with CRC is listed in online supplemental table 1. Gallinarum is a potential prophylactic for preventing CRC in humans.
Many of the summaries of evidence are confounded by poor trial methodology, lack of strain or dose definition, short follow up, absence of quality control for the probiotic product, and low statistical power. Future work should aim to eradicate these flaws and further investment in research is needed from the companies that market such products. Nicole Future research needs to establish which species and strains are best at preventing and treating AAD and CDAD. Furthermore, research is needed to verify the best dose to use, to establish an ongoing robust safety record in groups at most risk of AAD and CDAD , and to explore the cost–benefit relationship of providing such preventative treatment.
I read another reviewer who used the word “stamina” and I think that’s the best word for it. I tried Floracil 50 because of the you tube presentation I saw. I bought it when it was discounted and used it till the bottle was empty. In some cases and depends on the person it might take a while to feel a complete difference.

Persistence of colonization of human colonic mucosa by a probiotic strain, Are 3000mg CBD Gummies enormously powerful? GG, after oral consumption. This will go hand in hand with the ongoing developments of omics technologies to monitor the impact of LGG application and to go towards a better understanding of responders and non-responders. Atopic dermatitis in children could not be treated by LGG in three independent trials, using a daily concentration of 5×109 CFU/100 ml formula , 5×109 CFU in milk or 1010 CFU in milk . However, in these trails there was a consistent but not significant effect of LGG in the IgE-sensitized subgroup. Two other trials also reported that treatment (5×109 CFU daily in milk) was efficient in IgE-sensitized infants, but not in non-IgE-sensitized infants .
Although many intervention studies with LGG are targeting the GIT, it is also interesting to investigate extra-intestinal effects of LGG. For instance, LGG has been shown to reduce oral counts of Streptococcus mutans, a bacterium correlated with caries formation, respectively in yogurt, milk and lozenges [ ]. Especially long-term consumption of LGG containing milk (5-10 × 105 CFU) appears to be able to reduce caries development in children . Importantly, LGG appears not to ferment sucrose to a significant level , indicating that it is itself not cariogenic, a property which is sometimes attributed to lactobacilli due to lactic acid production. A predictive model is presented that describes the non-Arrhenius behaviour of growth and survival kinetics of food bacteria, in both the growth phase and lag phase of growth as influenced by temperature, in a wide range of foods and media.

Plantarum WCFS1 , also indicated a remarkable metabolic flexibility of LGG in the murine gastro-intestinal tract (Sarah Lebeer et al., in preparation). An additional paper was published using the original 380 women and study design from the postnatal depression study. The only difference was this research looked at GDM rates. As before, the gold standard study included 380 women who were split to receive either L. Rhamnosus HN001 or placebo from weeks gestation to six months post birth.
