Awassi sheep sera from all the provinces of the Syrian Arab Republic were tested for RSV, P13, REO and Adeno viruses (IIF and AGID tests). RSV was the most prevalent infection with 63.6% of samples seropositive, followed by REO, P13 and Adenovirus with seroprevalences of 27.3%, 24% and 8.1% respectively. Animals were more frequently infected by RSV alone. Mixed infections were also identified but the occurrence was not high. The RSV and REO virus infections occurred more frequently when transhumant flocks travelled for long distances (P < 0.001). The prevalence of RSV, P13, REO and Adenovirus infections was higher in animals sheltered in poor conditions compared to those in good shelter or with no shelter (P < 0.001; P < 0.001; n.s.; P < 0.05, respectively). RSV and P13 infections were related to an adult mortality rate of 10 to 20% (P < 0.001); REO virus was also proportionally related to mortality from low to high rates (P < 0.05). Concerning mortality of lambs, only Adenovirus infection was related to losses (> 20%) (P < 0.001). REO virus was related to low milk yield (P < 0.05).
对来自阿拉伯叙利亚共和国所有省份的阿瓦西绵羊血清进行了呼吸道合胞病毒(RSV)、P13、呼肠孤病毒(REO)和腺病毒检测(间接免疫荧光法和琼脂凝胶免疫扩散试验)。RSV是最普遍的感染病毒,63.6%的样本血清呈阳性,其次是REO、P13和腺病毒,血清阳性率分别为27.3%、24%和8.1%。动物更常单独感染RSV。也发现了混合感染,但发生率不高。当游牧羊群长途迁徙时,RSV和REO病毒感染更频繁发生(P<0.001)。与生活在良好庇护所或无庇护所的动物相比,生活在条件较差庇护所的动物中RSV、P13、REO和腺病毒感染的患病率更高(分别为P<0.001;P<0.001;无显著差异;P<0.05)。RSV和P13感染与10%至20%的成年动物死亡率相关(P<0.001);REO病毒也与从低到高的死亡率成比例相关(P<0.05)。关于羔羊死亡率,只有腺病毒感染与损失(>20%)相关(P<0.001)。REO病毒与低产奶量相关(P<0.05)。
