摘要: 为掌握福建某规模化獭兔场兔球虫病的流行情况,采用麦克马斯特计数法(McMaster's method)和饱和氯化钠溶液漂浮法,对采集的494份獭兔粪便样品中兔球虫感染情况和卵囊种类进行调查分析。结果显示,该獭兔场兔球虫总感染率和平均每克粪便卵囊数(OPG值)分别为87.45%和2.56×104,各日龄段均有感染,其中以40日龄左右兔和65日龄左右兔感染率最高,分别达98.61%和98.95%;30日龄以下哺乳仔兔感染率和OPG值均最低,分别为19.23%和331,且该场兔球虫卵囊的OPG值分布符合负二项分布。本次调查共检出11种兔艾美耳球虫,均为混合感染,感染球虫种类多为3~7种;其中感染比例最高的4种兔球虫依次为穿孔艾美耳球虫(20.15%)、中型艾美耳球虫(16.79%)、小型艾美耳球虫(13.94%)和大型艾美耳球虫(13.48%)。

Abstract: In order to investigate coccidium infection of a Rex rabbit farm in Fujian province, 494 fecal samples were collected from different ages of Rex rabbits and examined by McMaster's method and the method of saturated saline flotation.The results showed that the total prevalence was 87.45% and the mean oocysts per gram (OPG) value was 2.56×104.The prevalences of coccidia among each rabbit age were different, and it was highest at the age of about 40 d (98.61%) and about 65 d (98.95%) rabbits.The prevalence and OPG values at the age under 30 d (19.23% and 331) were significantly lower, and the distribution pattern of OPG values was negative binomial distribution in rabbits by using fitting of distributions.In total, 11 species of Eimeria were identified from oocyst-positive samples.The infection of Eimeria was mixed infection with more than two Eimeria species, and mostly of which were infected by 3 to 7 Eimeria species.The dominant species of Eimeria were E.perforans, E.media, E.exigua and E.magna, and their prevalences were 20.15%, 16.79%, 13.94% and 13.48%, respectively.
