在海水鱼类中,致病力最强的寄生虫是被称为“海水鱼白点病”的病原--刺激隐核虫(Cryptocaryon irritus)。它寄生在鱼的体表、鳃,引起鱼的活动异常、上皮增生、呼吸困难以及机械损伤继而带来病原菌的继发感染等病状。 刺激隐核虫是一种寄生于热带、亚热带海水鱼类的遍生性(周身遍布纤毛)纤毛虫。在野生的海洋鱼类,很少引起疾病,
Among the marine fish, the most virulent parasite is the pathogen called Cryptocaryon irritus, known as the “white spot disease of marine fish.” It is parasitic on the body surface of fish, gills, causing abnormal fish activity, epithelial hyperplasia, dyspnea and mechanical damage which in turn leads to the pathogens secondary infection and other symptoms. Cryptosporidium is a parasitic tropical, sub-tropical marine fish species (all over the ciliate) ciliates. In the wild marine fish, rarely cause disease,
