Abstract
The supplementation of antimicrobial growth promoters (AGPs) has been banned in many countries because of the emergence of antimicrobial-resistant pathogens in poultry products and the environment. Probiotics have been broadly studied and demonstrated as a promising AGP substitute. Our study is centred on the effects of a multi-strain Bacillus-based probiotic product on broiler production performance and gut microbial profile in a dexamethasone-induced leaky gut challenge. Two hundred and fifty-six broiler chicks were hatched and randomly assigned into four groups (wheat-soybean meal basal diet (BD) = non-supplemented control (C), BD supplemented with dexamethasone in week 4 (CD), BD containing a probiotic from day one (P), and BD containing a probiotic from day one and supplemented with dexamethasone during challenge week 4 (PD)). The production performance and caecal, gizzard, jejunal lumen and jejunal mucosa swab microbiota were studied by 16S rRNA gene sequencing. The Bacillus probiotic product significantly improved production performance and altered caecal gut microbiota (p ≤ 0.05), but no significant impact on microbiota was observed in other gut sections.

Abstract
Probiotic supplements consumed adequately at the proper time can affect health by modulating inflammatory pathways in gastrointestinal epithelial cells and modifying the resultant inflammatory response. The current study applied in vitro models to investigate the effectiveness of probiotics in modulating inflammatory pathways and altering inflammatory gene expression in gastrointestinal epithelial cells, with the ultimate goal of promoting probiotic consumption as a therapeutic and preventive measure for chronic inflammatory bowel conditions. HT-29 cells were treated with Gram-negative bacteria to evaluate the changes in pathways related to inflammation activities before and after treatment with a Lactobacillus spp. cocktail (L. plantarum, L. rhamnosus, L. brevis, and L. ruteri) and a Bifidobacterium spp. cocktail (B. bifidum, B. langum, and B. breve) using the real-time PCR method and ELISA for IL-1β and IL-6 as pro-inflammatory cytokines. The results showed that the expression of NF-κB signaling pathway genes and IL-1β and IL-6 cytokines increased after exposure to Gram-negative components. In contrast, all probiotic combinations significantly decreased the expression of genes and the secretion of cytokines. However, this decrease was significantly smaller in cells that underwent probiotic treatment after inflammation induction. In addition, cocktails containing combined Lactobacillus and Bifidobacterium demonstrated robust anti-inflammatory activity relative to solo cocktails. Our observations confirm that probiotic consumption could positively impact inflammatory conditions and alleviate inflammatory symptoms; they can be particularly effective as a preventive measure. Our study provides preliminary evidence to support the lifetime consumption of probiotics.

Abstract
Over the last few decades, numerous studies have evaluated probiotic use for the prevention of necrotising enterocolitis in preterm babies. Early 'proof of concept' studies evaluating whether probiotics are capable of colonising the preterm gut have translated into multiple observational studies, small and large randomised controlled trials. Some show evidence of benefit while others have produced disappointing results. In this paper, we review the history of probiotic use in preterm babies for NEC prevention in an attempt to explain why uncertainty exists and why this intervention has not been universally adopted into routine neonatal practice.

Abstract
The gut microbiota plays a crucial role in gastrointestinal health. Current use of probiotics is aimed at modulating the bacterial gut composition to alleviate specific diseases. The safety and tolerance of three probiotic strains (Bifidobacterium longum subsp. infantis R0033, Lactobacillus helveticus R0052 and Bifidobacterium bifidum R0071) has recently been described. The objective of the present study was to analyse the microbiological composition and immunological parameters of faecal samples obtained from healthy infants from 3 to 12 months of age after receiving either one of the three probiotic strains or placebo for 8 weeks. 16S ribosomal RNA gene sequencing and multiplexing technology was used for analysis. Faecal sample analysis showed that the most abundant genus in all four groups of infants pre- and post-intervention was Bifidobacterium, representing approximately 50% of the sequences. After the intervention period the microbial composition of faecal samples in the probiotic groups did not display notable changes. In contrast, a decrease in different Bifidobacterium species, such as B. bifidum and Bifidobacterium breve and an increase in Bacteroides, Blautia, Clostridium, Coprococcus and Faecalibacterium genera was observed in the placebo group. The analysis of a wide range of immune factors in faecal samples suggests a modulatory effect by these three probiotic strains during the intervention period. The anti-inflammatory ratio interleukin (IL)-10/IL-12 increased at the end of the intervention period in the B. infantis R0033 group while the TNF-α/IL-10 ratio increased in the L. helveticus R0052 group. The decrease of the IL-10/IL-12 ratio together with the increase of the tumour necrosis factor alpha (TNF-α)/IL-10 ratio demonstrated a pro-inflammatory profile in the placebo group. In conclusion, the species profile of the microbiome observed in all three probiotic groups resembled that of a younger infant, similar to an unweaned infant, when compared to the placebo group which may also be related with an anti-inflammatory effect.

Abstract
Some strains of species belonging to the genera Bifidobacterium and Lactobacillus are used in order to maintain health. Although these organisms have a long record of safe use, it is important to assess their safety and tolerance in potentially vulnerable populations, such as infants. The objective of this study was to evaluate the safety and tolerance of three probiotic strains (Bifidobacterium longum subsp. infantis R0033, Bifidobacterium bifidum R0071 and Lactobacillus helveticus R0052) in healthy infants aged 3 to 12 months. A multi-centre randomized, double-blind, placebo-controlled intervention study with 221 healthy full-term infants was conducted. Infants received either a placebo or one of the 3 probiotic strains (3×109 cfu) daily during an 8 week intervention period. Growth (weight, height and head circumference), adverse events (AEs)/serious adverse events (SAEs), concentrations of D-lactic acid in urine samples, characteristics of the stools and use of medication were collected for safety evaluation. All 4 groups were homogeneous with respect to age, gender, feeding type, ethnicity, height, weight and head circumference at the start of the study. The results showed that changes in growth (weight, height and head circumference) were equivalent in all 4 groups. No SAEs were reported. Total number of AEs recorded was equivalent in all groups. Thus, the use of B. infantis R0033, L. helveticus R0052 and B. bifidum R0071 in infancy is safe, and well tolerated.

Abstract
GOALS To assess the effectiveness of Bifidobacterium breve B632 and BR03 association in the reduction of infants crying over time. The second endpoint was to observe the effect of the same strains on daily evacuations and on the number of regurgitations and vomits. BACKGROUND Infant colics represent a clinical condition in childhood, characterized by an uncontrollable crying that occurs without any apparent organic cause. An altered intestinal microbiota composition in the very first months may induce intestinal colics in infants. Thus far, no treatment is really effective for this problem, but recent literature shows an increasing attention toward probiotics. STUDY A total of 83 subjects were enrolled, 60 breastfed infants and 23 bottle-fed infants. Sixty of them carried out the study: 29 infants were given probiotics, whereas 31 placebo. During the 90 days of the study, parents were asked to give 5 drops of active product (10 viable cells/strain) or placebo and to daily take note of: minutes of crying, number, color, and consistency of evacuations, and number of regurgitations or vomits. RESULTS No significant differences were detected in the infants treated with probiotics, compared with placebo group (P=0.75). The analysis of the 3 months of treatment demonstrated that during the third month, the probiotic group cried 12.14 minutes on average and the placebo cried 46.65 minutes. This difference is statistically significant (P=0.016). CONCLUSIONS The evidence of the usefulness of some probiotic strains in the treatment and prevention of infant colics is growing, and therefore their use in clinical practice is spreading.

Abstract
The relative expression of mucin, pro- and anti-inflammatory genes besides other signaling molecules in HT-29 cells by two test probiotic strains of Lactobacillus plantarum Lp9 and Lp91 and the reference strain L. plantarum 5276 was evaluated by RT-qPCR using Relative Expression Software Tool qBase-Plus under in vitro simulated gut conditions. Ten house keeping genes were evaluated by using geNorm 3.4 excel based application. The most stable genes were RPL27, ACTB and B2M which were subsequently used for calculating the normalization factor. Under pretreatment conditions (4 h probiotic treatment, followed by lipopolysaccharide challenge for 3 h), all the three strains evoked downregulation of IL-8 expression by ~100 %, while in case of TNF-α, the downregulation of the relative gene expression was at the rate of 98.2, 93.8 and 98.0 % with Lp5276, Lp9 and Lp91, respectively, under the same set of conditions. Lp91 evoked maximum downregulation of IL12p35 and IFN-γ with corresponding fold reduction in relative expression of the two genes by 96.5 and 96.7 % during pre-treatment conditions. However, IL-10 and IFN-α were significantly upregulated to the extent of 8.13 ± 0.36 and 2.62 ± 0.14 fold by Lp91 under the same conditions. Lp9 and Lp91 were also quite effective in inducing the expression of Cox-1 and Cox-2 in HT-29 cells as can be reflected from their ratios, i.e., 5.90 and 6.50 (under pretreatment conditions); 3.79 and 4.36 (under co-culture conditions). Thus, the two putative indigenous L. plantarum strains Lp9 and Lp91 demonstrated immunomodulating functions in HT-29 cells at significant levels under different experimental conditions.

Abstract
Background Meta-analyses on the effects of probiotics on specific gastrointestinal diseases have generally shown positive effects on disease prevention and treatment; however, the relative efficacy of probiotic use for treatment and prevention across different gastrointestinal diseases, with differing etiology and mechanisms of action, has not been addressed. Methods/Principal Findings We included randomized controlled trials in humans that used a specified probiotic in the treatment or prevention of Pouchitis, Infectious diarrhea, Irritable Bowel Syndrome, Helicobacter pylori, Clostridium difficile Disease, Antibiotic Associated Diarrhea, Traveler's Diarrhea, or Necrotizing Enterocolitis. Random effects models were used to evaluate efficacy as pooled relative risks across the eight diseases as well as across probiotic species, single vs. multiple species, patient ages, dosages, and length of treatment. Probiotics had a positive significant effect across all eight gastrointestinal diseases with a relative risk of 0.58 (95% (CI) 0.51–0.65). Six of the eight diseases: Pouchitis, Infectious diarrhea, Irritable Bowel Syndrome, Helicobacter pylori, Clostridium difficile Disease, and Antibiotic Associated Diarrhea, showed positive significant effects. Traveler's Diarrhea and Necrotizing Enterocolitis did not show significant effects of probiotcs. Of the 11 species and species mixtures, all showed positive significant effects except for Lactobacillus acidophilus, Lactobacillus plantarum, and Bifidobacterium infantis. Across all diseases and probiotic species, positive significant effects of probiotics were observed for all age groups, single vs. multiple species, and treatment lengths. Conclusions/Significance Probiotics are generally beneficial in treatment and prevention of gastrointestinal diseases. Efficacy was not observed for Traveler's Diarrhea or Necrotizing Enterocolitis or for the probiotic species L. acidophilus, L. plantarum, and B. infantis. When choosing to use probiotics in the treatment or prevention of gastrointestinal disease, the type of disease and probiotic species (strain) are the most important factors to take into consideration.

Abstract
Background and aims: The purpose of this study was to investigate the efficacy of a synbiotic supplementation in reducing common winter diseases in children. Methods: A randomized, double-blind, placebo-controlled, multicentre study was conducted in young school-age children (3—7 years old) during a winter period. Participants were otherwise healthy children who suffered from at least three episodes of ear, nose and throat (ENT), respiratory tract or gastrointestinal illness during the previous winter. They were supplemented daily with either a synbiotic preparation (Lactobacillus helveticus R0052, Bifidobacterium infantis R0033, Bifidobacterium bifidum R0071, and fructooligosaccharide) or a matched placebo for 3 months. Over this period, all emergent health episodes of any type were recorded by parents in a diary. They were checked by investigators at regular monthly visits. The main study outcome was the percentage of children free of any episode during the study course. Results: We randomized 135 children (mean age: 4.1±1.0 years) to the synbiotic group ( n = 62) or placebo ( n = 73) group. At least one illness episode was reported in 32 children in the synbiotic group and 50 in the placebo group (51.6% versus 68.5%). This corresponded to a significant 25% relative risk reduction (95% CI 0.6—44.3%; p = 0.045). This difference was due to a decrease in the number of children who suffered from at least one ENT, respiratory tract or gastrointestinal disorder (50.0% with synbiotic versus 67.1% with placebo; p = 0.044). At least one sickness school day loss was noted in 25.8% of children with the synbiotic as compared with 42.5% with placebo ( p = 0.043). No treatment related side effects were detected in either group. Conclusions: This study suggests that a 3-month supplementation with this synbiotic preparation can decrease the risk of occurrence of common infectious diseases in children and limits the risk of school day loss.

Abstract
OBJECTIVE To test the efficacy of Lactobacillus reuteri on infantile colic and to evaluate its relationship to the gut microbiota. STUDY DESIGN Fifty exclusively breastfed colicky infants, diagnosed according to modified Wessel's criteria, were randomly assigned to receive either L reuteri DSM 17 938 (10(8) colony-forming units) or placebo daily for 21 days. Parental questionnaires monitored daily crying time and adverse effects. Stool samples were collected for microbiologic analysis. RESULTS Forty-six infants (L reuteri group: 25; placebo group: 21) completed the trial. Daily crying times in minutes/day (median [interquartile range]) were 370 (120) vs 300 (150) (P=.127) on day 0 and 35.0 (85) vs 90.0 (148) (P=.022) on day 21, in the L reuteri and placebo groups, respectively. Responders (50% reduction in crying time from baseline) were significantly higher in the L reuteri group versus placebo group on days 7 (20 vs 8; P=.006), 14 (24 vs 13; P=.007), and 21 (24 vs 15; P=.036). During the study, there was a significant increase in fecal lactobacilli (P=.002) and a reduction in fecal Escherichia coli and ammonia in the L reuteri group only (P=.001). There were no differences in weight gain, stooling frequency, or incidence of constipation or regurgitation between groups, and no adverse events related to the supplementation were observed. CONCLUSION L. reuteri DSM 17 938 at a dose of 10(8) colony-forming units per day in early breastfed infants improved symptoms of infantile colic and was well tolerated and safe. Gut microbiota changes induced by the probiotic could be involved in the observed clinical improvement.

Abstract
OBJECTIVE The goal was to test the hypothesis that oral administration of Lactobacillus reuteri in a prospective randomized study would improve symptoms of infantile colic. METHODS Ninety breastfed colicky infants were assigned randomly to receive either the probiotic L. reuteri (10(8) live bacteria per day) or simethicone (60 mg/day) each day for 28 days. The mothers avoided cow's milk in their diet. Parents monitored daily crying times and adverse effects by using a questionnaire. RESULTS Eighty-three infants completed the trial: 41 in the probiotic group and 42 in the simethicone group. The infants were similar regarding gestational age, birth weight, gender, and crying time at baseline. Daily median crying times in the probiotic and simethicone groups were 159 minutes/day and 177 minutes/day, respectively, on the seventh day and 51 minutes/day and 145 minutes/day on the 28th day. On day 28, 39 patients (95%) were responders in the probiotic group and 3 patients (7%) were responders in the simethicone group. No adverse effects were reported. CONCLUSIONS In our cohort, L. reuteri improved colicky symptoms in breastfed infants within 1 week of treatment, compared with simethicone, which suggests that probiotics may have a role in the treatment of infantile colic.
