Abstract

Background: Anaplasma sp. is a blood protozoon that causes economic damage to the livestock industry. Therefore, studying this disease’s epidemiology and distribution pattern in different regions is essential. Objectives: This study aimed to investigate the variety of infections of the Anaplasma sp. in the sheep population of Khuzestan Province in Iran. Methods: A total of 200 sheep blood samples were randomly collected and examined using specific nested polymerase chain reaction (nPCR) based on the 16S rRNA gene. Results: The prevalence of Anaplasma phagocytophilum was 17%, and infected sheep had no clinical signs. The effective risk factors in the spread of infection in Khuzestan Province include sheep aged 3-5 years, low sanitation, high-density farms, use of acaricides in the field, and hot season (P≤0.05). There was no significant association between the occurrence of A. phagocytophilum infection and variables of altitude, farm type, vectors, distance from other farms, and sex. Conclusion: Since the infection often has no clinical symptoms, identifying the risk factors and epidemiology is essential to develop control and prevention planning.
伊朗胡齐斯坦省绵羊饲养中噬细胞嗜血杆菌的流行率、风险因素和分子流行病学研究
背景:阿纳疟原虫是一种血液原生动物,会对畜牧业造成经济损失。因此,研究这种疾病在不同地区的流行病学和分布模式至关重要。研究目的本研究旨在调查伊朗胡齐斯坦省(Khuzestan Province)绵羊群体中感染解脲脲原体(Anaplasma sp.)的种类。方法:随机采集 200 份绵羊血液样本,使用基于 16S rRNA 基因的特异性巢式聚合酶链反应(nPCR)进行检测。结果噬细胞原虫的感染率为 17%,受感染的羊没有临床症状。在胡齐斯坦省,感染传播的有效风险因素包括 3-5 岁的羊、卫生条件差、高密度养殖场、田间使用杀螨剂和炎热季节(P≤0.05)。噬菌体感染的发生与海拔、农场类型、病媒、与其他农场的距离和性别等变量之间没有明显的关联。结论由于噬菌体感染通常没有临床症状,因此确定风险因素和流行病学对于制定防控计划至关重要。
