Abstract

Background

Influenza is among the most common viruses affecting humans and many animals worldwide. While influenza A (IAV) and D (IDV) viruses are associated with respiratory disease in humans and animals, respectively, their prevalence in the Middle East is unknown.

Methods

Here, we assessed the seroprevalence of IDV and IAV/H1N1 in 331 ruminants (including camels, sheep, cattle, and goats) in Qatar. Sera samples were collected from ruminants in different farms and titrated by hemagglutination inhibition (HAI) assay.

Results

We showed a high prevalence of IDV in all ruminants, ranging between 55 and 84 %, with the highest rates seen in sheep and cattle. The rates were much lower for IAV, ranging between 6 and 8 %, but were not detectable in goats. HAI titers of IDV-seropositive samples ranged between 20 and 2560, whereas IAV titers ranged between 20 and 640.

Conclusions

Our study provides the first serological evidence of IDV and IAV/H1N1 in ruminants in Qatar. These results underscore the need for further investigation into the role of ruminants in influenza virus transmission.

卡塔尔反刍动物甲型H1N1流感和丁型流感病毒的血清流行率

流感是影响人类和许多动物的最常见病毒之一。虽然甲型流感（IAV）和丁型流感（IDV）病毒分别与人类和动物的呼吸道疾病有关，但它们在中东的流行情况尚不清楚。方法在卡塔尔对331只反刍动物（包括骆驼、绵羊、牛和山羊）进行IDV和IAV/H1N1的血清检测。采集不同养殖场的反刍动物血清，采用血凝抑制（HAI）法进行滴定。结果IDV在所有反刍动物中都有很高的流行率，在55%到84%之间，其中绵羊和牛的发病率最高。IAV的感染率要低得多，在6%至8%之间，但在山羊中未检测到。idv血清阳性样本的HAI滴度在20至2560之间，而IAV滴度在20至640之间。结论本研究首次为卡塔尔反刍动物提供了IDV和IAV/H1N1的血清学证据。这些结果强调需要进一步调查反刍动物在流感病毒传播中的作用。
