摘要
为了解广东粤西地区鸡传染性病毒性腺胃炎(Transmissible viral proventriculitis,TVP)的流行情况和主要病因,本研究于粤西地区部分发病鸡场共采集910份(每10份混为1个样本,共91个样本)腺胃样品,使用实时荧光定量PCR检测方法对8种TVP相关病毒进行检测。结果显示,91份样品中检测出42份相关病毒核酸阳性,阳性率46.2%;共检出TVP相关病毒6种,发现有病毒双重感染和混合感染情况。该地区病鸡无品种特异性,但小鸡和中鸡病毒感染率差异显著。这表明粤西地区养鸡场普遍存在TVP感染,本研究为粤西地区TVP的流行规律研究及防控提供基础数据。
In order to investigate the prevalence and main causes of transmissible viral proventriculitis(TVP)in chickens in western Guangdong,we collected a total of 910 glandular gastric samples(every 10 mixed into 1 pool sample,a total of 91 pool samples)from some chicken farms in western Guangdong province,and detected 8 kinds of TVP-related viruses using real-time PCR method.The results indicated that 42 out of the 91 samples were positive,with a positive rate of 46.2%,and a total of 6 kinds of TVP-related viruses were detected,and double or multiple infection were found.There is no breed specificity for infected chickens in this area,but infection rate among different age groups varies significantly.It suggests that TVP infection is widespread in chicken farms in western Guangdong province,and our data will provide basic information for the epidemic characteristics as well as prevention and control of TVP in Western Guangdong.
