The first step in understanding gut microbial ecology is determining the presence and potential niche breadth of associated microbes. While the core gut bacteria of adult honey bees is becoming increasingly apparent, there is very little and inconsistent information concerning symbiotic bacterial communities in honey bee larvae. The larval gut is the target of highly pathogenic bacteria and fun...

ABSTRACT The gut microbiota plays an important role in human health. In modern life, with the improvement of living conditions, intake high-sugar and high-fat diets as well large-scale use antibacterial drugs have extensive impact on microbiota, even leading to microbiota-orchestrating disorders. This review discusses effects various factors, including geographic location, age, diet, drugs, psy...

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 (i-t), feeding with inulin-enri...

The bacterial flora of marine animals collected at depths of 570 to 2,446 m was examined for population size and generic composition, and the barotolerant characteristics of selected bacterial isolates were determined. Total numbers of culturable, aerobic, heterotrophic bacteria were found to be low in animals collected at the greatest ocean depths sampled in this study. Vibrio spp. were predom...

The bacterial community associated with the midgut of three Brazilian Lutzomyia longipalpis (Lutz & Neiva) populations, two from endemic areas for visceral leishmaniasis (Jacobina, Bahia State and São Luís, Maranhão State) and one from a non-endemic area (Lapinha Cave, Minas Gerais State), was identified. Five groups, 35 females each, from each population were separated; a total of 175 females ...

Phagocytes patrol intestinal fungi Maintaining a healthy balance of gut bacteria can promote good health. Leonardi et al. show that fungi can also interact with gut immune cells to maintain intestinal wellbeing. CX3CR1 mononuclear phagocytes (MNPs) patrol the intestine and promote antifungal immunity. Genetic deletion of CX3CR1 in MNPs caused colitis-like symptoms in mice. CX3CR1 polymorphisms ...
