从患病河蟹蚤状幼体体内分离出的病原菌为副溶血性弧菌;人工回感染实验表明副溶血性弧菌是导致河蟹蚤状幼体发病的病原;其对氧哌嗪青霉素、呋喃西林高度敏感。副溶血性弧菌可以通过食物和水体感染河蟹蚤状幼体。加强消毒措施有利于对该病的预防。
Vibrio parahaemolyticus was isolated from diseased crab flea larvae. Artificial retroviruses showed that Vibrio parahaemolyticus was the most common pathogen of crab-like larvae and was highly sensitive to piperacillin and nitrofurazone. Vibrio parahaemolyticus can infect crab flea larvae through food and water. Strengthening disinfection measures are conducive to the prevention of the disease.
