1993年作者对河南信阳市南湾水库网箱养殖鲤鱼肠道单极虫病进行了系统研究。该地区发病率高达 90 %以上 ,发病鲤鱼肠壁上寄生了大量单极虫孢囊 ,破坏肠道组织 ,吸收鱼体营养 ,病鱼失去光泽 ,体色呈暗黑色 ,肠管呈紫红色 ,充满脓血粘液 ,大型孢囊集中在中、后肠 ,孢囊形态大多为椭球形 ,最大个体为 4 .5× 2 .5cm ,肠管膨大一倍以上 ,肠壁变薄 ,肠道完全被堵塞 ,停止进食而死亡。经比较研究 ,该病原体被定为信阳单极虫新种 (Thelohanellusxinyangensissp .nov .)。作者对感染和未感染鲤鱼血清进行了免疫试验 ,发现病鲤血清蛋白带比未感染粘孢子虫鲤鱼血清多 5— 7条 ,该血清与单极虫孢子经交叉免疫电泳发生沉淀反应 ,表明病鲤血清具有特异性抗体产生。作者在病鲤血液中还发现“未明血液生物体”(UBO) ,对肝、肠组织亦进行了病理学研究
In 1993, the author systematically studied the intestinal monocytopenias of carps in Nanwan Reservoir in Xinyang City, Henan Province. The incidence of up to 90% in the region, the incidence of carp intestinal wall parasitic monocytogenes large number of monocytogenes, destruction of intestinal tissue, absorption of fish nutrition, fish diseased luster, body color was dark black, bowel was purple, full Pus blood mucus, large cysts concentrated in the hindgut, cyst morphology mostly ellipsoid, the largest individual is 4.5 × 2.5cm, bowel more than doubled, thinning of the intestinal wall, the intestine is completely blocked, Stop eating and die. After comparative study, the pathogen was identified as the new species of Monochamus alternatus (Thelohanellus xinyangensissp. Nov.). The author of the infected and uninfected carp serum immune tests and found diseased carp serum protein band than non-infected Mycosporidium carp serum 5-7, the serum and monocytogenetic spores by cross-immunoprecipitation precipitation reaction, indicating that the disease Carp serum with specific antibody production. The author also found in the diseased carp blood “unknown blood organism” (UBO), the liver, intestinal tissue also conducted a pathological study
