【摘要】：为掌握禽偏肺病毒(aMPV)在安徽省鸡群中的感染状况,采用酶联免疫吸附试验(ELISA)对安徽省合肥、亳州、定远、舒城等地区的9个鸡场、7个不同品种(系)鸡群的296份血液样本进行了aMPV血清抗体检测。结果表明,所有被检鸡场均有aMPV感染,鸡场阳性率最高达100%,最低为20%;各品种(系)鸡均有感染,感染率最高的是青脚麻肉鸡,其次分别为科宝肉鸡、海兰蛋鸡、禽粤黄蛋鸡、淮南麻黄鸡、黄羽土鸡和新广麻肉鸡;其中蛋用型鸡血清样本总体阳性率为88.7%,明显高于肉用和兼用型鸡;公鸡和母鸡血清抗体阳性率均较高。研究结果表明,安徽省鸡群aMPV的感染已广泛存在,且不同地区、品种(系)、用途和性别的鸡群均较严重,应根据感染状况尽早制定相应的防控对策。
[Abstract]:In order to understand the infection status of AMPV in chickens of Anhui Province, the enzyme linked immunosorbent assay (Elisa) was used to treat Hefei, Bozhou, Dingyuan, Anhui Province. AMPV serum antibodies were detected in blood samples from 9 farms and 7 different breeds (lines) of chickens in Shucheng and other areas. The results showed that all the farms were infected with aMPV, and the positive rate was 100, and the lowest was 20. The infection rate was the highest in all breeds (lines), and the highest in all breeds (lines), followed by Kebao broiler, Hailan layer and Guangdong yolk laying hens. The total positive rate of serum samples of Huainan ephedra chicken, yellow feather native chicken and Xinguangma broiler was 88.7, which was obviously higher than that of both meat type and concurrently type chicken, and the positive rate of serum antibody was higher in male chicken and hen chicken. The results showed that the infection of aMPV in flocks of Anhui Province had been widespread, and the flocks of different breeds (lines, uses and sexes) were more serious in different areas, so the corresponding countermeasures should be worked out according to the situation of infection as soon as possible.
