摘要
本工作共调查笼养猕猴250只,发现有结肠小袋纤毛虫寄生者91只,检得虫体(滋养体及包囊)2365个,测量了144个原虫的长度和宽度,并观察了它们的外形,分析了猴的感染情况,其中仔猴感染率占42.86％,病态猴42.85％,检疫猴群中有本原虫感染的占42.5％。长期饲养的猴群感染率为24.42％。年龄在5岁以上者感染率低。栖息笼舍的构造和卫生管理工作对感染率影响较大。仔猴的感染与亲代阳性猴有关。一年四季均可感染,而以冬季为高。
250 rhesus monkeys breeding in the house were examined for B. coli. The following is the result of B. coli found in this examination:
We obtained 2365 B. coli from the investigation. Among them observe the Trophozoites were 144 individual and the Cyst 144 individual. The Trophozoites measure 30-180 μm in length (averge 108 ± 37.68 μm) , and 20-114.4 μm in width (average 57.51 ± 37.98 μm) . The Cysts measure 39.6-61.6 μm (average 48.65 ± 6.89 μm) in length and width. To see table 1.
The infection rate was found to be 36.4%, with the young group aocounting for 42.86%, the ill group for 42.85%, the .quaratined group for 42.50%, the long-term-breeting monkeys for 24.42%, and that its infection rate of 5 and more year old group is lower than that of group of 4 year old below. Of importance to the infection rate of B. coli is the atructure and sanitation of breeding cottages. It is also found that male monkeys are as susceptible as female monkeys and that the B. coli in young monkeys comes down from their while its infection rate is higher than that of their parents. The monkeys could be infected by this B. coli during all seasons, with its higher rate in winter seasons.
The parasitic number of 91 positive monkeys was found to be 1 -220 individual (Trophozoite and Cyst). To see table 2.
The morphology and diagnosis and infected state and so on B. coli on related problems were discussed in this paper.
