摘　　要：通过对上海一家水产养殖公司在１９９１～１９９２年度发生的暴发性疾病的现场检测和病原分离，获得了Ｓ－１、Ｓ－２菌株。经人工感染试验对健康亲虾具很强的致病力，出现与自然病虾相同的症状并在人工感染病虾上分离出同样性状的菌株。证实了这二菌株是该病的致病菌。通过菌体形态、培养特性和生理生化反应，鉴定为莫格球拟酵母。通过药物筛选，配制出沼虾－Ⅰ和沼虾－Ⅱ药饵，对预防及早期治疗效果良好。While culturing of parent prawn, an explosive epidemic disease happened during 1991-1992 in a cultivating fishery company in Shanghai. The mortality was very high. 18 prawns of random sampling were surveyed in situ. The uniform microorganism was found under microscrope in 17 prawns. S-1,S-2 strains were obtained from haemolymph and liver of sick prawn on plate PDA. During the infection experiment, the symptom was as same as that of the sick one. S-3,S-4 strains were isolated from the infectious prawn. All the characteristics of S-3,S-4 were similar to S-1,S-2. S-1,S-2 were proved to be the pathagenic organism, and identified to be Torulopsis mogii. The kinds of effective medicine food(Prawn-Ⅰ,Prawn-Ⅱ) were developed for prevention and cure of the disease.
