Abstract

Studies were carried out on the etiology and epizootiology of rabbit coccidiosis. Three experimental groups of rabbits were infected with intestinal, liver, and mixed intestinal and liver coccidia. The shedding of oocysts and the clinical course of the disease were followed up, with description of the morphologic changes and the results of the biochemical examinations of the blood. A total of eight species of coccidia were established in all cases--Eimeria magna, E. intestinalis, E. piriformis, E. media, E. exigua, E. irresidua, E. perforans, and E. stidae. Predominating were E. magna, E. perforans, and E. irresidua. Results showed that all age groups of rabbits were susceptible to the coccidial infection, mostly the weaned bunnies and young ones aged 2-3 months. It is admitted that under the present conditions of this country's rabbit raising coccidiosis is a disease of a seasonal character. Biochemical investigations of blood taken from experimentally infected rabbits revealed that the changes in the activity of GOT and alkaline phosphatase and in the amount of bilirubin were most pronounced.

摘要

对兔球虫病的病因和流行病学进行了研究。将三组实验兔分别感染肠道球虫、肝脏球虫以及肠道和肝脏混合球虫。对卵囊排出情况和疾病临床进程进行了跟踪，描述了形态学变化以及血液生化检查结果。所有病例中共鉴定出8种球虫——大型艾美耳球虫、肠艾美耳球虫、梨形艾美耳球虫、中型艾美耳球虫、微小艾美耳球虫、残余艾美耳球虫、穿孔艾美耳球虫和斯氏艾美耳球虫。其中以大型艾美耳球虫、穿孔艾美耳球虫和残余艾美耳球虫为主。结果表明，所有年龄段的兔都易感染球虫，以断奶幼兔和2至3月龄的幼兔最为易感。公认在该国目前的养兔条件下，球虫病是一种具有季节性的疾病。对实验感染兔采集的血液进行生化研究发现，谷草转氨酶和碱性磷酸酶活性以及胆红素含量的变化最为明显。
