Tilapia gut microbiota affected by the infection with Staphylococcus haemolyticus and Providencia vermicola, two potential emerging pathogens for the fish aquaculture

The rapid intensification of tilapia aquaculture has also resulted in losses due to emerging pathogens. The gastrointestinal microbiota plays a vital role in the host's health by modulating the immune system and several physiological functions; however, bacterial pathogens may deleteriously affect the microbiota structure. This study analyzed the effect of challenging tilapia with two emerging bacterial pathogens: Staphylococcus haemolyticus and Providencia vermicola, on the stomach and intestinal microbiota.
