陕西省羊肺腺瘤病分子流行病学调查

Molecular Epidemiological Survey of Ovine Pulmonary Adenomatosis in Shaanxi Province

绵羊肺腺瘤病(OPA)是一种主要在肺脏形成肿瘤为特征的传染病。近年来发现布尔山羊等山羊也易感染,而且每年造成的损伤无法统计。本病目前尚无特效药物,也没有可用的疫苗,只能对症治疗。迄今分子生物学中的PCR技术是唯一可靠的检测方法。对陕西省25个羊场进行检测,总阳性率为54.8%,其中山羊的平均的感染率为57.1%,绵阳为57.7%,并且布尔山羊的感染率最高(83.4%)。初步得出,引入我省的绵羊品种时间越长,发病率越高;本地区培育的山羊品种抗该病的能力相对较高。该结果对我省肉羊健康养殖过程中的引种、疫病防控等都具有一定的指导意义。

Ovine pulmonary adenomatosis （OPA） is an infectious disease characterized chiefly by the formation of tumors in the lungs. In recent years, it reported that Boer goats and other goats are susceptible to infection, and the damage cannot be counted. So far, there is no specific drug, or vaccine available, only symptomatic treatment is being used, and, PCR technology is the only reliable detection method in molecular biology. 25 farms in Shaanxi province were tested, results showed that the total positive rate was 54.8 %, and the average infection rate of goat and sheep was 57.1% and 57.7%, respectively, and the infection rate of Boer goat was the highest （83.4%）： It is concluded that the longer breeds of sheep husbandry in our province, the higher incidence. The goat breeds cultivated in the region have relatively high resistance to the disease. The result has certain significance for the introduction of breeds on healthy culture and disease prevention and control.
