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.

罗非鱼水产养殖业的快速集约化发展，同样因新型病原微生物的出现造成了损失。宿主的胃肠道微生物群（gastrointestinal microbiota）可通过调节免疫系统与多项生理功能，对宿主健康发挥至关重要的作用；然而细菌性病原微生物会对微生物群结构产生不利影响。本研究针对两种新型细菌性病原——溶血葡萄球菌（Staphylococcus haemolyticus）与维氏普罗威登斯菌（Providencia vermicola）攻毒罗非鱼的实验，分析了其对罗非鱼胃及肠道微生物群的影响。
