Research on the interaction between dietary vitamins and intestinal bacteria is poorly understood. To investigate the effect of dietary vitamins on the cecal bacterial communities, 2 bacterial 16S rRNA gene clone libraries were constructed from pooled PCR products obtained from the cecal digesta of 28-d broilers fed diets with vitamins (V) at the NRC level or with no vitamins (NV). The results ...

Intestinal microbe-host interactions can affect the feed efficiency (FE) of chickens. As inconsistent findings for FE-associated bacterial taxa were reported across studies, the present objective was to identify whether bacterial profiles and predicted metabolic functions that were associated with residual feed intake (RFI) and performance traits in female and male chickens were consistent acro...

Gut microbiota has diverse ecological and evolutionary effects on its hosts. However, the ways in which it responds to environmental heterogeneity and host physiology remain poorly understood. To this end, we surveyed intestinal microbiota of Holotrichia parallela larvae at different instars and from different geographic regions. Bacterial 16S rRNA gene clone libraries were constructed and clon...

Plant species, plant community diversity and microbial interactions can significantly impact soil microbial communities, yet there are few data on the interactive effects of plant species and plant community diversity on soil bacterial communities. We hypothesized that plant species and plant community diversity affect soil bacterial communities by setting the context in which bacterial interac...

Intestinal bacterial communities play an important role in the growth and health of aquatic animal hosts have drawn increasing attention. However, intestinal microbiota freshwater prawns remains unclear. Here, (Macrobrachium rosenbergii) at different life stages (one, two, three months old) were investigated using 16S rRNA sequencing. The results showed that community richness diversity increas...

The intestinal microbiota of 10 pups (five from dam A and five from dam B) in the suckling stage (18 days old) and at maturity (40 days old) were compared with those of their dams to assess the mechanisms of bacterial transmission during development of intestinal microbiota in the rat model. Fecal samples were subjected to amplified ribosomal DNA restriction analysis and 65 operational taxonomi...
