BACKGROUND The intestinal microbiome represents a complex network of microbes that are important for human health and preventing pathogen invasion. Studies that examine differences in intestinal microbial communities across individuals with and without enteric infections are useful for identifying microbes that support or impede intestinal health. RESULTS 16S rRNA gene sequencing was conducte...

The effect of pathogenic bacteria on a host and its symbiotic microbiota is vital and widespread in the biotic world. The soil-dwelling opportunistic bacterium Bacillus nematocida B16 uses a "Trojan horse" mechanism to kill Caenorhabditis elegans. The alterations in the intestinal microflora that occur after B16 infection remain unknown. Here, we analyzed the intestinal bacteria presented in no...

To investigate the effects of Xiaoning liquid on gut microbiota in mouse during asthma. A total 60 mice were randomly and averagely assigned to healthy control group, budesonide group. The later three groups used establish an Ovalbumin (OVA) asthma model. intestinal bacterial communities compared among using 16S rRNA gene amplification. Analyzing structure with OTU analysis, Shannon-Wiener, PCA...

Numerous bacteria are responsible for hydrolysis of proteins during cheese ripening. The raw milk flora is a major source bacterial variety, starter cultures needed successful acidification the and proteolytic strains like Lactobacillus helveticus, added flavor improvement or acceleration ripening processes. To study impact higher diversity in on protein simulated human digestion, Raclette-type...

The microbial communities inhabiting the mammalian intestinal tract play an important role in diverse aspects of host biology. However, little is known regarding the forces shaping variation in these communities and their influence on host fitness. To shed light on the contributions of host genetics, transmission and geography to diversity in microbial communities between individuals, we perfor...

Some scholars caution that long-term ad libitum feeding with probiotic fermented food poses potential health risks to baby animals. We conducted a feeding experiment to investigate the influence of ad libitum feeding of pre-and post-weaned piglets with a Bacillus subtilis fermented diet on the gut microbiome, gut metabolomic profiles, bile acid metabolism, proinflammatory cytokines and faecal c...

To reveal the changes in gut microbiota of yellow catfish after being infected by Edwardsiella ictaluri, 16S rRNA gene high-throughput sequencing technology was used to analyze microbial composition and diversity healthy diseased catfish. The richness fish were significantly lower than those fish. predicted function drastically altered infection E. ictaluri. Fusobacteriota, Proteobacteria, Firm...

clostridium perfringens (c. perfringens) is related to gram-positive and anaerobic bacteria. this rod-shaped bacterium produces spores and can cause a wide spectrum of diseases in humans and animals. every of five different bacterium types can lead to different diseases. most of distinct bacterial recognition methods are not completely effective and practical in all condition. the objective of ...

The members of the Phyllostomidae, the New-World leaf-nosed family of bats, show a remarkable evolutionary diversification of dietary strategies including insectivory, as the ancestral trait, followed by appearance of carnivory and plant-based diets such as nectarivory and frugivory. Here we explore the microbiome composition of different feeding specialists: insectivore Macrotus waterhousii, s...

Necrotizing enterocolitis (NEC) is a significant cause of morbidity and mortality in premature infants; yet its pathogenesis remains poorly understood. To evaluate the role of intestinal bacteria in protection against NEC, we assessed the ability of naturally occurring intestinal colonizer E. coli EC25 to influence composition of intestinal microbiota and NEC pathology in the neonatal rat model...
