水貂犬瘟热流行病学调查

为了调查山东省水貂犬瘟热的流行病学情况,对2010年8月－2012年8月期间由诸城、文登等地养貂场送诊的996份水貂病例进行了临床诊断和病原学检查。结果显示,共检出犬瘟热病毒阳性病料223份,阳性率为22.39%。其中,犬瘟热病毒与其他病原混合感染136例,占阳性病例的60.99%;阳性样本中未免疫病例116个;诸城检出阳性病例数最多,为147例;3月龄水貂发病率最高,占阳性病例的43.0%;水貂感染犬瘟热病毒主要症状为眼、鼻黏液性分泌物增多、脚垫增厚、呼吸困难;主要病理变化为肠、脑部出血。结果表明,犬瘟热依然是危害水貂养殖的重要疫病,且犬瘟热病毒易与其他病原混合感染;免疫接种能有效预防水貂犬瘟热,且宜在3月龄以前进行。
