对叶尔羌鼓鳔鳅烂尾病的病变器官进行剖检和显微观察,并对病原菌进行分离培养、纯化,做药敏实验。导致叶尔羌鼓鳔鳅烂尾的病原菌为条件致病菌,培养后的菌体呈圆形、无色、半透明、微隆起状。该病原菌对卡那霉素、多黏菌素、庆大霉素、环丙杀星等抗菌素敏感,对氯霉素、痢特灵中敏,对其余抗菌药物不敏感。感染该病原菌的鱼尾鳍充血、溃烂,最后造成鳃、肝脏、肾脏等器官均产生不同程度的病变,直至死亡。联合或交替使用该病原菌敏感的药物,能收到较好的疗效。 The diseased organs of the yak crab loach disease were dissected and observed microscopically, and the pathogens were isolated, cultured and purified to make the susceptibility test. Lead to Erqiang drum Loach rotten pathogenic bacteria as a conditional pathogen, cultured cells were round, colorless, translucent, slightly elevated shape. The pathogen kanamycin, polymyxin, gentamicin, cyclosporine and other antibiotics sensitive to chloramphenicol, furazolidone in the sensitivity of the remaining antimicrobials are not sensitive. Infection of the pathogen fish tail fin congestion, ulceration, and finally cause gills, liver, kidney and other organs have varying degrees of disease, until death. Joint or alternate use of the pathogen-sensitive drugs, can receive better efficacy.
