Abstract
The effect of fish oil (FO) on colonic function, immunity, and microbiota was investigated in Vibrio parahaemolyticus (Vp)-infected C57BL/6J mice. Mice intragastrically presupplemented with FO (4.0 mg) significantly reduced Vp infection as evidenced by stabilizing body weight and reducing disease activity index score and immune organ ratios. FO minimized colonic pathological damage, strengthened the mucosal barrier, and sustained epithelial permeability by increasing epithelial crypt depth, goblet cell numbers, and tight junctions and inhibiting colonic collagen accumulation and fibrosis protein expression. Mechanistically, FO enhanced immunity by decreasing colonic CD3+ T cells, increasing CD4+ T cells, downregulating the TLR4 pathway, reducing interleukin-17 (IL-17) and tumor necrosis factor-α, and increasing immune cytokine IL-4 and interferon-γ levels. Additionally, FO maintained colonic microbiota eubiosis by improving microbial diversity and boosting Clostridium, Akkermansia, and Roseburia growth and their derived propionic acid and butyric acid levels. Collectively, FO alleviated Vp infection by enriching beneficial colonic microbiota and metabolites and restoring immune homeostasis.

Mani J, Levy S, Angelova A, Hazrati S, Fassnacht R, Subramanian P, Richards T, Niederhuber JE, Maxwell GL, Hourigan SK. Epidemiological and microbiome associations of Clostridioides difficile carriage in infancy and early childhood. Gut Microbes 2023; 15:2203969. [PMID: 37096914 PMCID: PMC10132246 DOI: 10.1080/19490976.2023.2203969] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Accepted: 04/12/2023] [Indexed: 04/26/2023] Open
Abstract
There has been an increase in the prevalence of Clostridioides difficile (C. diff) causing significant economic impact on the health care system. Although toxigenic C. diff carriage is recognized in infancy, there is limited data regarding its longitudinal trends, associated epidemiolocal risk factors and intestinal microbiome characteristics. The objectives of our longitudinal cohort study were to investigate temporal changes in the prevalence of toxigenic C.diff colonization in children up to 2 years, associated epidemiological and intestinal microbiome characteristics. Pregnant mothers were enrolled prenatally, and serial stool samples were collected from their children for 2 years. 2608 serial stool samples were collected from 817 children. 411/817 (50%) were males, and 738/817 (90%) were born full term. Toxigenic C.diff was detected in 7/569 (1%) of meconium samples, 116/624 (19%) of 2 m (month), 221/606 (37%) of 6 m, 227/574 (40%) of 12 m and 18/235 (8%) of 24 m samples. Infants receiving any breast milk at 6 m were less likely to be carriers at 2 m, 6 m and 12 m than those not receiving it. (p = 0.002 at 2 m, p < 0.0001 at 6 m, p = 0.022 at 12 m). There were no robust differences in the underlying alpha or beta diversity between those with and without toxigenic C. diff carriage at any timepoint, although small differences in the relative abundance of certain taxa were found. In this largest longitudinal cohort study to date, a high prevalence of toxigenic C. diff carrier state was noted. Toxigenic C. diff carrier state in children is most likely a transient component of the dynamic infant microbiome.

Gut Microbiota Diversity of Preterm Neonates Is Associated With Clostridioides Difficile Colonization. Front Cell Infect Microbiol 2022; 12:907323.

Abstract
In adults, Clostridioides difficile infections are associated with alterations of the intestinal bacterial populations. Although preterm neonates (PN) are frequently colonized by C. difficile, limited data are available regarding the relationship between C. difficile and the intestinal microbiota of this specific population. Therefore, we studied the intestinal microbiota of PN from two multicenter cohorts using high-throughput sequencing of the bacterial 16S rRNA gene. Our results showed that alpha diversity was significantly higher in children colonized by C. difficile than those without colonization. Beta diversity significantly differed between the groups. In multivariate analysis, C. difficile colonization was significantly associated with the absence of postnatal antibiotherapy and higher gestational age. Taxa belonging to the Lachnospiraceae, Enterobacteriaceae, Oscillospiraceae families and Veillonella sp. were positively associated with C. difficile colonization, whereas Bacteroidales and Bifidobacterium breve were negatively associated with C. difficile colonization. After adjustment for covariables, Clostridioides, Rothia, Bifidobacterium, Veillonella, Eisenbergiella genera and Enterobacterales were more abundant in the gut microbiota of colonized children. There was no significant association between C. difficile colonization and necrotizing enterocolitis in PN. Our results suggest that C. difficile colonization in PN is related to the establishment of physiological microbiota.

Abstract
The prevalence of inflammatory bowel disease (IBD) is increasing, which is concerning because IBD is a known risk factor for the development of colorectal cancer. Emerging evidence highlights environmental factors, particularly dietary factors and gut microbiota dysbiosis, as pivotal inducers of IBD onset. Goji berry, an ancient tonic food and a nutraceutical supplement, contains a range of phytochemicals such as polysaccharides, carotenoids, and polyphenols. Among these phytochemicals, L. barbarum polysaccharides (LBPs) are the most important functional constituents, which have protective effects against oxidative stress, inflammation, and neurodegeneration. Recently, the beneficial effects of goji berry and associated LBPs consumption were linked to prebiotic effects, which can prevent dysbiosis associated with IBD. This review assessed pertinent literature on the protective effects of goji berry against IBD focusing on the gut microbiota and their metabolites in mediating the observed beneficial effects.

Abstract
Clostridioides difficile infection (CDI) in children with inflammatory bowel disease (IBD) can present and manifest differently from the general population with CDI, and it can worsen the underlying disease course. Furthermore, current clinical assays used to test for CDI do not accurately distinguish between true CDI or colonization. This uncertainty leads to difficulty in identifying the etiology and therapy for symptomatic patients with IBD. Improved diagnostic tests, biomarkers, and safe and effective treatment options are greatly needed for this vulnerable population.

Abstract
The gut epithelium is a habitat of a variety of microorganisms, including bacteria, fungi, viruses and Archaea. With the advent of sophisticated molecular techniques and bioinformatics tools, more information on the composition and thus function of gut microbiota was revealed. The gut microbiota as an integral part of the intestinal barrier has been shown to be involved in shaping the mucosal innate and adaptive immune response and to provide protection against pathogens. Consequently, a set of biochemical signals exchanged within microbes and communication between the microbiota and the host have opened a new way of thinking about cancer biology. Probiotics are living organisms which administered in adequate amounts may bring health benefits and have the potential to be an integral part of the prevention/treatment strategies in clinical approaches. Here we provide a comprehensive review of data linking gut microbiota to cancer pathogenesis and its clinical course. We focus on gastrointestinal cancers, such as gastric, colorectal, pancreatic and liver cancer.

Abstract
Clostridioides difficile infections (CDI) result from antibiotic use and cause severe diarrhea which is life threatening and costly. A specific probiotic containing Lactobacillus acidophilus CL1285, Lacticaseibacillus casei LBC80R, and Lacticaseibacillus rhamnosus CLR2 has demonstrated a strong inhibitory effect on the growth of several nosocomial C. difficile strains by production of antimicrobial metabolites during fermentation. Though there are several lactobacilli shown to inhibit C. difficile growth by processes relying on acidification, this probiotic has demonstrated potency for CDI prevention among hospitalized patients. Here, we describe the acid-dependent and independent mechanisms by which these strains impair the cytotoxicity of a hypervirulent strain, C. difficile R20291 (CD). These bacteria were co-cultured in a series of experiments under anaerobic conditions in glucose-rich and no-sugar medium to inhibit or stimulate CD toxin production, respectively. In glucose-rich medium, there was low CD toxin production, but sufficient amounts to cause cytotoxic damage to human fibroblast cells. In co-culture, there was acidification by the lactobacilli resulting in growth inhibition as well as ≥ 99% reduced toxin A and B production and no observable cytotoxicity. In the absence of glucose, CD produced much more toxin. In co-culture, the lactobacilli did not acidify the medium and CD growth was unaffected; yet, the amount of detected toxin A and B was decreased by 20% and 41%, respectively. Despite the high concentration of toxin, cells exposed to the supernatant from the co-culture were able to survive. These results suggest that in addition to known acid-dependent effects, the combination of L. acidophilus CL1285, L. casei LBC80R, and L. rhamnosus CLR2 can interfere with CD pathogenesis without acidification: (1) reduced toxin A and B production and (2) toxin neutralization. This might explain the strain specificity of this probiotic in potently preventing C. difficile-associated diarrhea in antibiotic-treated patients compared with other probiotic formulae.

Abstract
Intestinal microbiota transplantation (IMT) is an effective therapy for recurrent Clostridioides difficile infections in patients with inflammatory bowel disease (IBD). However, further research is needed to understand the safety of this procedure, particularly given the frequency of gastrointestinal symptoms and of IBD treatment escalation after IMT.

Abstract
In people, colonization with Clostridioides difficile, the leading cause of antibiotic-associated diarrhea, has been shown to be associated with distinct gut microbial features, including reduced bacterial community diversity and depletion of key taxa. In dogs, the gut microbiota features that define C. difficile colonization are less well understood. We sought to define the gut microbiota features associated with C. difficile colonization in puppies, a population where the prevalence of C. difficile has been shown to be elevated, and to define the effect of puppy age and litter upon these features and C. difficile risk. We collected fecal samples from weaned (n = 27) and unweaned (n = 74) puppies from 13 litters and analyzed the effects of colonization status, age and litter on microbial diversity using linear mixed effects models. Colonization with C. difficile was significantly associated with younger age, and colonized puppies had significantly decreased bacterial community diversity and differentially abundant taxa compared to non-colonized puppies, even when adjusting for age. C. difficile colonization remained associated with decreased bacterial community diversity, but the association did not reach statistical significance in a mixed effects model incorporating litter as a random effect. Even though litter explained a greater proportion (67%) of the variability in microbial diversity than colonization status, we nevertheless observed heterogeneity in gut microbial community diversity and colonization status within more than half of the litters, suggesting that the gut microbiota contributes to colonization resistance against C. difficile. The colonization of puppies with C. difficile has important implications for the potential zoonotic transfer of this organism to people. The identified associations point to mechanisms by which C. difficile colonization may be reduced.
