AIM
The present cross-sectional study aimed at assessing the seroprevalence of infection both at herd and within herd and at determining risk factors that are associated with its seropositivity.
MATERIALS AND METHODS
A total of 90 cows distributed over seven herds located in two North-Eastern Algerian provinces were blood sampled in order to be tested for the presence of antibodies against using a commercially available enzyme-linked immunosorbent assay kit.
RESULTS
The individual seroprevalence of was found to be 12.22%, and six of the seven herds tested had at least one seropositive cow. The logistic regression model revealed that abortion (odds ratio [OR]=29.15) and parity (OR=7.38) were positively associated with the seropositivity of animals on an individual basis.
CONCLUSION
The study confirms the existence of infection in cattle in North-Eastern Algeria. However, a widespread infection rate of 85.71% and its significant statistical association with previous abortion (OR=29.15) need further investigations.
目的
本横断面研究旨在评估畜群和畜群内部感染的血清流行率，并确定与其血清阳性相关的风险因素。
材料与方法
对分布在阿尔及利亚东北部两个省份七个畜群中的90头奶牛进行采血，以便使用市售酶联免疫吸附测定试剂盒检测抗[具体感染物未明确]抗体的存在情况。
结果
[具体感染物未明确]的个体血清流行率为12.22%，七个检测畜群中有六个至少有一头血清阳性奶牛。逻辑回归模型显示，流产（比值比[OR]=29.15）和胎次（OR=7.38）与个体动物的血清阳性呈正相关。
结论
该研究证实阿尔及利亚东北部牛群中存在[具体感染物未明确]感染。然而，85.71%的广泛感染率及其与先前流产的显著统计学关联（OR=29.15）需要进一步调查。
