鱼类的(?)疮病在我国各地养殖区虽不是一种严重的流行病,但也时有所见,而且无明显的流行季节,一年四季常有发现,感染的对象也很广泛,几年来我们在实际工作中,常见到鲤、青及草等几种主要养殖鱼类均时有罹及。该病的特征是在鱼体表皮的局部组织上生有与人类(?)疮病相似的脓疮,发病的部位没有一定,常处于鱼体的两侧或背鳍基部附近,罹病的鱼在将死亡时,观察到脓疮内部肌肉组织溃疡成脓血交加的液体,如直接涂片检查,可见有大量的细菌及白血球。谷川英一等均报告鲑鳟鱼类常罹此病,王德铭氏也报导过草、青及鲤鱼有(?)疮病,但对此种鱼类病原菌的研究尚无专题报导。本文是报导我们对鲤鱼(?)疮病病原菌的分离与鉴定的初步结果。 Fish disease (?) Sores throughout the country, although not a serious epidemic, but also seen from time to time, and no obvious epidemic season, often found throughout the year, the object of infection is also very broad, In the past few years, we have seen frequent occurrence of several major cultured fish such as carp, grass and grass in actual work. The disease is characterized by the local organization of the epidermis on the human body with (?) Sore disease similar abscess, the incidence of the site is not certain, often in the fish on both sides or near the base of the dorsal fin, diseased fish in the will At the time of death, ulceration of the inner muscular tissue ulcer in the abscess was observed as a liquid for the addition of sepsis. For example, direct smear examination revealed a large amount of bacteria and white blood cells. Tachikawa et al reported salmon trout often suffer from the disease, Wang Deming’s also reported that grass, green and carp have (?) Sore, but there is no special report on the study of fish pathogens. This article is the first to report our findings on the isolation and characterization of the pathogen of carp (?) Sores.
