摘要
目的为了解重庆市猪场球虫感染情况。方法选取重庆市9个县14个猎场作为采样点,对被检猪采用直肠取粪法或采集猪刚排出的新鲜粪便,饱和食盐水漂浮法收集卵囊,镜检观察。对收集到的卵囊进行培养,待其孢子化后进行种类鉴定。结果14个猪场均感染了球虫,球虫的平均感染率为33.83%,阳性率最高的场为76.09%;仔猪感染率为41.87%,后备猪感染率为26.33%,种猪感染率为67.80%。发现8种艾美耳属球虫和1种等孢属球虫,分别是猪艾美耳球虫(检出率13.56%),豚艾美耳球虫(检出率41.59%),有刺艾美耳球虫(检出率12.84%),平滑艾美耳球虫(检出率4.70%),新蒂氏艾美耳球虫(检出率10.49%),蒂氏艾美耳球虫(检出率11.03%),粗糙艾美耳球虫(检出率2.35%),极细艾美耳球虫(检出率3.07%),及猪等孢球虫(检出率0.36%)。结论重庆市猪球虫感染率较高,应加强猪球虫病的防制。
Epidemiology of swine coccidiosis was investigated in 14 pig farms in Chongqing. Coccidia present in 14 pig farms in which the highest infection rate was 76.09%, and mean infection rate was 33.83% ; the infection rate of piglets,young pigs and sows were 41.87% ,26.33% and 67.80% respectively. Eight species of Eimeria were identified as follow : Eimeria suis ( 13.56% ), E. porci ( 41.59% ), E. spinosa ( 12.84% ), E. polita (4.70 % ), E. neodebliecki ( 10.49% ), E. debliecki ( 11.03 % ) , E. scabra ( 2.35 % ), E. perminuta ( 3.07 % ), and one species of Isospora : Isospora suis (0.36%).
