温州地区家兔球虫病流行病学调查

Epidemiological investigation of rabbit coccidiosis in Wenzhou area

为掌握温州地区家兔球虫病的流行情况,采用麦克马斯特虫卵计数法(McMaster's method)和饱和盐水漂浮法,对采集的595份家兔粪便样品中兔球虫种类和感染情况进行调查分析。结果表明,温州地区兔球虫平均感染率达77.1%,全部为混合感染,感染球虫种类多为3～5种。各月龄段均有不同程度的感染,以1～3月龄幼兔感染率最高,达97.7%,多数呈中度或重度感染。调查共检出10种兔艾美耳球虫,以无残艾美耳球虫、穿孔艾美耳球虫、肠艾美耳球虫和大型艾美耳球虫为优势虫种。

In order to grasp the current infection of rabbit coccidiosis in Wenzhou area ,595 fresh faecal pellets were collected from 3 counties and examined by McMaster counting and the method of saturated saline flotation to investigate species and the prevalence of Eimeria infections in domestic rabbits . The results showed overall prevalence of infections was 77.1%, all of infection were mixed infection , mostly of which were infected by three to five Eimeria species .The infection rates of coccidia among each rabbit age were different ,the infection rate of rabbits aged 1-3 months was 97.7%, and most of them had more oocysts than the elder rabbits .Ten species of Eimeria were identified from oocyst-positive samples ,the more prevalent species were E.irrestidua, E.perfomns, E.intestinalis and E.magna.Above results would provide the effectiveness of future control strategies against rabbit coccidiosis .
