摘　　要：为掌握海南省文昌鸡传染性贫血(CIAV)的流行情况,分别从海南省4个文昌鸡主要养殖地区海口、文昌、琼海和儋州的14个不同规模未免疫CIA疫苗的文昌鸡场采集血液样品1709份,采用ELISA检测CIAV抗体。结果显示,1709份血液样品共检出阳性样品564份,文昌鸡的CIAV抗体总阳性率为33%;4个地区的文昌鸡场均有不同程度的CIAV感染,其中儋州市文昌鸡的CIAV抗体阳性率最高,达到55%;成年文昌鸡的CIAV感染程度高于其他生长阶段鸡,抗体阳性率达到53.63%;CIAV在一年四季均有发生,以冬季高发,抗体阳性率为48.06%;不同规模文昌鸡场CIAV的感染率存在差异,以中小规模文昌鸡场的CIAV感染程度较高,抗体阳性率分别为41.48%和40.10%;在不同类型的文昌鸡群中商品代蛋鸡的CIAV抗体阳性率最高,达到62.62%。结果表明,CIAV在海南省文昌鸡养殖地区普遍存在,且在冬季、成年文昌鸡中高发,以商品代蛋鸡感染最为严重,因此,应针对性地加强对海南省文昌鸡传染性贫血的防控。In order to understand the prevalence of infectious anemia(CIAV)in Wenchang chickens,1709 serum samples were collected from 14 Wenchang chicken farms that were not immunized with CIA vaccine in Haikou,Wenchang,Qionghai and Danzhou,and ELISA was used to detect CIAV antibody.The results showed that 564 of the 1709 serum samples were positive,and the total positive rate of CIAV antibody in Wenchang chickens was 33%.There were CIAV infections in Wenchang chicken farms in four areas,and the positive rate of CIAV antibody in Wenchang chickens of Danzhou was the highest,reaching 55.63%.The CIAV infection degree of adult Wenchang chickens was higher than that of other growth stage chickens,and the antibody positive rate reached 53.63%.CIAV occurred in all seasons of the year,especially in winter,with a positive rate of 48.06%.The CIAV infection rates of Wenchang chicken farms at different scale were different.The CIAV infection degree in middle and small size Wenchang chicken farms was higher,and the antibody positive rate was 41.48%and 40.10%,respectively.The positive rate of CIAV antibody of commercial laying hens was the highest among different types of Wenchang hens,reaching 62.62%.The results showed that CIAV was common in Wenchang chicken breeding area of Hainan province,and the incidence was high in winter and adult Wenchang chickens,and commercial laying hens were the most seriously infected.Therefore,the prevention and control of infectious anemia of Wenchang chickens should be strengthened.
