Peste des Petits Ruminants (PPR) is a highly infectious disease caused by a virus member of the genus Morbillivirus, which mainly affects goats, sheep and wild ruminants. It is considered one of the most significant transboundary infectious diseases and represents an animal health concern in developing countries. Spain is considered a PPR-free country. Nevertheless, given its geographical proximity to countries in North Africa where PPR virus (PPRV) has been circulating in recent years, the south of Spain can be considered a risk area for the introduction of PPRV. The aim of the present study was to assess circulation of PPRV in domestic and wild ruminant species in this country. During the period 2015-2017, a total of 910 sera from domestic, wild and captive ruminants were analysed using a commercial blocking ELISA to detect antibodies against PPRV. None of the 910 (0.0%; 95% CI: 0.0-0.3) animals tested were positive for anti-PPRV antibodies. To the best of our knowledge, this is the first serosurvey study of PPR in Spain. The results indicate absence of circulating PPRV in the south of Spain during the study period. Due to the risk of PPRV introduction into European countries of the Mediterranean basin, epidemiological surveillance should be maintained and extended in this region.
小反刍兽疫（PPR）是一种由副黏病毒科麻疹病毒属的病毒引起的高度传染性疾病，主要影响山羊、绵羊和野生反刍动物。它被认为是最重要的跨界传染病之一，也是发展中国家关注的动物健康问题。西班牙被认为是无小反刍兽疫国家。然而，鉴于其与北非国家的地理位置相近，近年来这些国家一直存在小反刍兽疫病毒（PPRV）的传播，西班牙南部地区可被视为 PPRV 传入的风险地区。本研究旨在评估该国国内和野生反刍动物物种中 PPRV 的循环情况。在 2015-2017 年期间，使用商业阻断 ELISA 分析了来自国内、野生和圈养反刍动物的总共 910 份血清，以检测针对 PPRV 的抗体。在 910 份（0.0%；95%CI：0.0-0.3）检测动物中，均未检测到抗 PPRV 抗体呈阳性。据我们所知，这是西班牙首次对小反刍兽疫进行血清学调查研究。结果表明，在研究期间，西班牙南部没有循环的 PPRV。由于 PPRV 可能传入地中海盆地的欧洲国家，因此应在该地区保持并扩大流行病学监测。
