Abstract

Peste des petits ruminants (PPR) is a viral disease affecting sheep and goats caused by peste des petits ruminants virus (PPRV) has a serious economic impact due to the restrictions on animal trade and animal movements and high mortality rates in small ruminant populations. The common clinical sings of the PPR are fever, muco-purulent nasal discharge, diarrhoea and abortion. Seroepidemiological studies of PPRV infection in sheep and goats in Turkey are scant. Therefore, this study was aimed to evaluate the seroprevalence of PPR in small ruminants in Turkey. Ovine blood samples were collected by random sampling method from sheep (n = 77) and goats (n = 61) from unvaccinated flocks (n = 40) in the Antalya Province in the Mediterranean region of Turkey. A competitive enzyme-linked immunosorbent assay (c-ELISA) kit was used to detect antibodies against PPRV in sera samples. Out of 138 sera samples analysed, eighteen sera samples (13%, 95% CI: 7.4 - 18.7) were PPRV seropositive, of which 18.2% (95% CI: 9.6 - 26.8; 14/77) were from sheep, whereas 6.6% (95% CI: 0.3 - 12.8; 4/61) were from goats. Although PPRV seropositivity rate was higher in sheep than goats, it was not statistically significant (P = 0.07). PPRV seropositivity was higher in small ruminants older than 24 months (19.4%) compared with less than or equal to 24 months (7%) (P = 0.04). Although, there was no statistically significant difference between sexes, PPRV seropositivity rate was higher (14.5%) in females than males (10.9%) (P = 0.61). The flock-level seroprevalence was 30% (12/40). The result of the present study showed that seroprevalence of PPRV infection is high in sheep and goats in the Antalya Province. However, results of the study are not enough to determine the regional and country-based profile of the PPRV infection in Turkey. Further epidemiological studies are required to get more epidemiology data on PPR in Turkey.

土耳其地中海地区小反刍动物小反刍兽疫病毒抗体调查

小反刍兽疫（PPR）是由小反刍兽疫病毒（PPRV）引起的一种影响绵羊和山羊的病毒性疾病，由于对动物贸易和动物移动的限制以及小反刍兽群的高死亡率，该病对经济造成了严重影响。小反刍兽疫常见的临床症状是发烧、流粘液脓性鼻涕、腹泻和流产。有关土耳其绵羊和山羊感染 PPRV 的血清流行病学研究很少。因此，本研究旨在评估土耳其小型反刍动物的 PPR 血清流行率。研究人员采用随机抽样法采集了土耳其地中海地区安塔利亚省未接种疫苗的羊群（40 只）中的绵羊（77 只）和山羊（61 只）的绵羊血样。使用竞争性酶联免疫吸附试验（c-ELISA）试剂盒检测血清样本中的 PPRV 抗体。在分析的 138 份血清样本中，18 份血清样本（13%，95% CI：7.4 - 18.7）PPRV 血清阳性，其中 18.2%（95% CI：9.6 - 26.8；14/77）来自绵羊，而 6.6%（95% CI：0.3 - 12.8；4/61）来自山羊。虽然绵羊的 PPRV 血清阳性率高于山羊，但并无统计学意义（P = 0.07）。24 个月以上的小反刍动物（19.4%）的 PPRV 血清阳性率高于小于或等于 24 个月的小反刍动物（7%）（P = 0.04）。虽然性别之间没有显著的统计学差异，但雌性的 PPRV 血清阳性率（14.5%）高于雄性（10.9%）（P = 0.61）。鸡群血清阳性率为 30%（12/40）。本研究结果表明，安塔利亚省绵羊和山羊的 PPRV 感染血清流行率较高。然而，研究结果还不足以确定土耳其地区和国家的PPRV感染情况。需要进一步开展流行病学研究，以获得更多有关土耳其PPR的流行病学数据。
