厦门市同安区羊群小反刍兽疫传入风险评估

Risk assessment of the introduction of PPRV on goats into Tongan county

通过对同安区羊群养殖、调运和检疫监管等情况的摸底调查,采集15个养殖场(户)合计90份鼻腔棉拭子和74份血清样品,分别采用荧光RT-PCR方法和酶联免疫吸附试验检测小反刍兽疫病原和抗体,评估该地区在小反刍兽疫强制免疫前传入羊群的风险。检测结果显示,同安区在未全面开展强制免疫前,小反刍兽疫抗体个体阳性率为25.7%,场(户)阳性率为33.3%,病原阳性率为0。初步判定,该地区在没有进行小反刍兽疫强制免疫的情况下,疫情发生的风险较大。提出应立即开展小反刍兽疫免疫、强化检疫监管、提高养殖户和屠宰场生物安全管理水平。

In order to understand the breeding and infection situation of PPR （Peste des Petits Ruminants） in Tongan county, an epidemiological investigation was conducted through questionnaire and sampling, 15 farms were chosen, 90 nasal cotton swabs and 74 serum samples were detected pathogen and antibody, respectively, and to evaluate the introduction risk in goats. The result showed that the individual antibody positive rate of PPR was 25.7%, the farm antibody positive rate of PPR was 33.3% and the pathogen positive rate was 0, therefore the risk of introduction is relatively high, then the suggestions were proposed such as PPR vaccination, intensifynig supervision towards inspection and quarantine, improving the farmers ability of prevention and breeding level and enhancing slaughtering bio-safety management.
