BACKGROUND: Although diet is known to have a major modulatory influence on gut microbiota, knowledge of the specific roles of particular vitamins, minerals, and other nutrients is limited. Modulation of the composition of the microbiota in pregnant women is especially important as maternal microbes are transferred during delivery and initiate the colonization process in the infant. We studied the associations between intake of specific dietary nutrients during pregnancy and gut microbiota composition...

5-Hydroxytryptamine (5-HT) produced by enterochromaffin (EC) cells is an important enteric mucosal signaling ligand and has been implicated in several gastrointestinal diseases, including inflammatory bowel disease and functional disorders such as irritable bowel syndrome. The present study reports a new, simple and rapid visualization method of 5-HT-producing EC cells utilizing detection of autofluorescence in paraffin-embedded tissue sections after formalin fixation. In human samples, there was a high incidence of autofluorescence+ cells in the 5-HT+ cells in the pyloric, small intestinal and colonic glands, while co-localization was lacking between autofluorescence+ and gastrin+ cells in the pyloric and small intestinal glands...

BACKGROUND: True vaginal prolapse is a rare condition in dogs and it is occasionally observed in animals with constipation, dystocia, or forced separation during breeding. If a true prolapse occurs, the bladder, the uterine body and/or distal part of the colon, may be present in the prolapse. CASE PRESENTATION: A 2-year-old intact non pregnant Central Asian Shepherd dog in moderate condition, was presented for a true vaginal and rectal prolapse. The prolapses were confirmed by physical examination and ultrasonography...

The mycotoxin deoxynivalenol (DON) is an abundant contaminant of cereal based food and a severe issue for global food safety. We report the discovery of DON-3-sulfate as a novel human metabolite and potential new biomarker of DON exposure. The conjugate was detectable in 70% of urine samples obtained from pregnant women in Croatia. For the measurement of urinary metabolites, a highly sensitive and selective LC-MS/MS method was developed and validated. The method was also used to investigate samples from a duplicate diet survey for studying the toxicokinetics of DON-3-sulfate...

Alteration of gut microbial colonization process may influence susceptibility of the newborn/infant to infectious and chronic disease. Infectious disease risk leads to widespread use of non-prescription antimicrobials in household products such as Triclocarban (TCC), an antimicrobial compound in personal care products. TCC concentrates in and is transferred through the milk to suckling offspring. TCC exposure during gestation and lactation significantly reduced phylogenetic diversity (PD) among exposed dams and neonates...

Infections due to clonal expansion of highly virulent bacterial strains are clear and present threats to human and animal health. Association of genetic changes with disease is now a routine, but identification of causative mutations that enable disease remains difficult. Campylobacter jejuni is an important zoonotic pathogen transmitted to humans mainly via the foodborne route. C. jejuni typically colonizes the gut, but a hypervirulent and rapidly expanding clone of C. jejuni recently emerged, which is able to translocate across the intestinal tract, causing systemic infection and abortion in pregnant animals...

Microorganisms colonize tissues and organs such as the skin and gastrointestinal, respiratory, and genitourinary systems. These microorganisms are generally called as "human microbiota". Human microbiota mostly consists of commensal microorganisms. The commensal microorganisms located on and in the human body are bacteria, fungi, viruses, archaea, and parasites. The microbiota genome is 100 times bigger in size than the human genome. Although the human genome is stationary, microbial genome has a compatible flexible variability during human life...

Antibiotic use continues to be the most important risk factor for the development of Clostridium difficile infection (CDI) through disruption of the indigenous microbiota of the colon. This factor, together with environmental contamination, makes hospital and other healthcare facilities the perfect breeding ground for the infection. Several groups of patients are exposed to the hospital environment and, at the same time, affected by conditions that can make CDI more prevalent, more severe or make it present a different clinical picture...

INTRODUCTION: Group B streptococcus (GBS) is the most common infectious agent responsible for early-onset bacterial sepsis (EOS) in term newborns. French prevention of perinatal GBS disease guidelines recommend screening for maternal vaginal GBS colonization at the 9th month of pregnancy, and use of intrapartum antibiotic prophylaxis (IAP) in case of detected GBS vaginal colonization. Peripheral bacterial sampling (gastric aspiration, ear, or meconium) and measurement of C-reactive protein (CRP) are performed in asymptomatic newborns in case of infectious risk factors and/or incomplete IAP...
