The present study was conducted to estimate the seroprevalence and associated risk factors of bovine herpesvirus 1 (BoHV-1) in a dairy herd in the northeast of Algiers, Algeria.
The target area is in the northeast of Algiers with humid to semi-dry climate and known for its economically important production of cattle. A total of 1,066 randomly selected individual blood samples of dairy herd collected at 120 dairy farms from rural districts of northeast of Algiers were evaluated with antibodies against BoHV-1 using commercial enzyme-linked immunosorbent assay kits, to determine the BoHV-1 infection status of the herds. A questionnaire submitted to the farmers during collection of the blood samples was used to collect data on potential BoHV-1 associated risk factors.
In the present study, the estimated farm and individual animal BoHV-1 seroprevalence levels were 58.33% and 14.16%, respectively. A logistic regression analysis of the random-effects model revealed that the significant associated risk factors for the present farm and individual animal seroprevalence levels were rural district, cattle introduced to the farm, region, and hygiene.
This study found higher seroprevalence of BoHV-1 in the northeast of Algiers. The results could be used in designing the prevention and control strategy of BoHV-1 in the northeastern part of Algeria.
本研究旨在评估阿尔及利亚阿尔及尔东北部一个奶牛场中牛疱疹病毒1型（BoHV-1）的血清流行率及相关风险因素。
目标区域位于阿尔及尔东北部，气候湿润至半干燥，以其重要的养牛业而闻名。从阿尔及尔东北部农村地区的120个奶牛场随机采集了1066份个体血样，使用商业酶联免疫吸附测定试剂盒检测针对BoHV-1的抗体，以确定牛群的BoHV-1感染状况。在采集血样时向养殖户发放问卷，收集有关潜在BoHV-1相关风险因素的数据。
在本研究中，估计的养殖场和个体动物的BoHV-1血清流行率分别为58.33%和14.16%。随机效应模型的逻辑回归分析显示，当前养殖场和个体动物血清流行率水平的显著相关风险因素为农村地区、引入养殖场的牛、地区和卫生状况。
本研究发现阿尔及尔东北部的BoHV-1血清流行率较高。研究结果可用于制定阿尔及利亚东北部BoHV-1的预防和控制策略。
