Intestinal microbial community composition of six Actinopterygii fish species in the Southeastern United States
The intestines of fish harbor a microbial community that aids digestion and prevents colonization by pathogens. Traditional methods of studying these communities have been cultivation dependent, yet many microorganisms are difficult to grow in the laboratory. In this study, gut microflora of six dif...
