Human breast milk is recognized as one of multiple important sources of commensal bacteria for infant gut. Previous studies searched for the bacterial strains shared between breast milk and infant feces by isolating bacteria and performing strain-level bacterial genotyping, but only limited number of milk bacteria were identified to colonize infant gut, including bacteria from Bifidobacterium, ...

Gut bacterial communities of bumble bees are correlated with defense against pathogens. Further understanding this host-microbe association is vitally important as bumble bees are currently experiencing global population declines, potentially due in part to emergent diseases. In this study, we used pyrosequencing and community fingerprinting (ARISA) to characterize the gut microbial communities...

Topological, chemical and immunological barriers are thought to limit infection by enteropathogenic bacteria. However, in many cases these barriers and their consequences for the infection process remain incompletely understood. Here, we employed a mouse model for Salmonella colitis and a mixed inoculum approach to identify barriers limiting the gut luminal pathogen population. Mice were infect...

The present study investigates the effects of different routes of inulin administration as prebiotic on gut microbiota and survival rate of Indian white shrimp post-larvae. Four hundred and fifty Indian white shrimp post-larvae (PL1) were stocked in nine tanks. The tanks were assigned into three treatments: feeding with inulin-treated (110 mg L-1) Artemia nauplii ...

Chronic inflammation is a non-traditional risk factor for cardiovascular mortality in the chronic kidney disease (CKD) population. In recent years, the gastrointestinal tract has emerged as a major instigator of systemic inflammation in CKD. Postmortem studies previously discovered gut wall inflammation throughout the digestive tract in chronic dialysis patients. In CKD animals, colon wall infl...

Accumulating evidence suggests that gut bacteria play a role in homeostasis of the circulatory system in mammals. First, gut bacteria may affect the nervous control of the circulatory system via the sensory fibres of the enteric nervous system. Second, gut bacteria-derived metabolites may cross the gut-blood barrier and target blood vessels, the heart and other organs involved in the regulation...

b a ckground: microbes particularly bacteria presenting in the gut of haematophagous insects may have an important role in the epidemiology of human infectious disease. m e t hods: the microbial flora of gut and surrounding environmental of a laboratory strain of phlebotomus papatasi , the main vector of zoonotic cutaneous leishmaniasis (zcl) in the old world, was investigated. biochemical reac...

Animals are not only regulated by their own genes but also influenced symbiotic bacteria, most of which colonized in the gut. The gut bacterial community is involved plenty physiological processes; therefore, intestinal colonization commensal microbiota essential to health host animal. Here, metagenome sequencing A. japonicus gut, surrounding water, and feed was performed explore structural fun...

BACKGROUND Age-related physiological changes in the gastrointestinal tract, as well as modifications in lifestyle, nutritional behaviour, and functionality of the host immune system, inevitably affect the gut microbiota, resulting in a greater susceptibility to infections. METHODOLOGY/PRINCIPAL FINDINGS By using the Human Intestinal Tract Chip (HITChip) and quantitative PCR of 16S rRNA genes ...
