Bovine anaplasmosis is a major tick-borne disease in ruminants, resulting in significant economic loss for the dairy sector. This study aimed to evaluate the seroprevalence of Anaplasma marginale (A. marginale) in buffaloes in three governorates in Nile Delta of Egypt.
A total of 400 serum samples from water buffaloes were examined using commercial cELISA kit.
The overall seroprevalence of A. marginale was 12.5% and Kafr ElSheikh governorate has the highest seroprevalence rate (15.28%). The seroprevalence was higher in females (13.33%) than males with non-significant difference. Moreover, adult animals older than 8 years exhibited a significant risk for A. marginale seropositivity (22.92%), particularly during the summer (22.52%) and autumn (13.73%). Significant differences (P < 0.05) in seroprevalence rates were observed between tick-infested animals (14.96%) and those not treated with acaricides (17.7%), highlighting the influence of tick infestation and lack of acaricidal intervention on infection rates.
The present study revealed the existence of antibodies against A. marginale in water buffaloes reared in Nile Delta of Egypt. Thus, the proper policies and control program should be adopted to reduce spreading of infection.
牛无形体病是反刍动物中一种主要的蜱传疾病，给乳制品行业造成重大经济损失。本研究旨在评估埃及尼罗河三角洲三个省份水牛中边缘无浆体（A. marginale）的血清阳性率。
使用商用cELISA试剂盒检测了400份水牛血清样本。
边缘无浆体的总体血清阳性率为12.5%，卡夫尔谢赫省的血清阳性率最高（15.28%）。雌性的血清阳性率（13.33%）高于雄性，但差异不显著。此外，8岁以上的成年动物边缘无浆体血清阳性的风险显著（22.92%），尤其是在夏季（22.52%）和秋季（13.73%）。在有蜱虫寄生的动物（14.96%）和未使用杀螨剂处理的动物（17.7%）之间观察到血清阳性率有显著差异（P < 0.05），突出了蜱虫寄生和缺乏杀螨剂干预对感染率的影响。
本研究揭示了在埃及尼罗河三角洲饲养的水牛中存在抗边缘无浆体的抗体。因此，应采取适当的政策和控制计划以减少感染传播。
