Bovine babesiosis represents a serious challenge for animal health, herd production, and profitability. Understanding the epidemiology and risk factors associated with babesiosis is critical to reduce their negative impacts.
Investigation of the seroprevalence and risk factors associated with () and () in five districts in Sharkia governorate using ELISA.
Across-sectional research was conducted to determine the seropositivity of babesiosis by collecting a total of 352 blood samples from 250 cattle and 102 buffaloes. A multivariate logistic regression model was implemented to evaluate the strength of the risk factors associated with both Babesia species infection.
The seroprevalence of and was 42.6% and 17.0 %, respectively. The prevalence of babesiosis in cattle was found to be 48.8% for and 16.8% for . Inclusive, in buffaloes, the prevalence was 27.5% for and 17.6% for . Adult animals were more vulnerable to infection with babesia than young animals by 3-5 times, respectively. Males were more susceptible to and than females by 3.7 and 3.5 times. Similarly, the odds of infection in infested animals with ticks were 2-4 times higher than in animals without ticks.
The obtained results revealed that age, sex of the animal, and tick infestation were major risk factors for the seropositivity of both Babesia species. Inclusive, there was no evidence to support the premise that seroprevalence of babesiosis is correlated with the season and species.
牛巴贝斯虫病对动物健康、畜牧业生产和盈利能力构成严重威胁。了解与巴贝斯虫病相关的流行病学和风险因素对于减轻其负面影响至关重要。
应用 ELISA 法调查在 Sharkia 省的五个地区牛巴贝斯虫病和埃及巴贝斯虫病的血清流行率及相关风险因素。
本研究采用横断面研究，共采集了 250 头牛和 102 头水牛的 352 份血液样本，以确定巴贝斯虫病的血清阳性率。采用多变量逻辑回归模型来评估与两种巴贝斯虫感染相关的风险因素的强度。
牛巴贝斯虫和埃及巴贝斯虫的血清阳性率分别为 42.6%和 17.0%。牛巴贝斯虫病的流行率在牛中为 48.8%，在水牛中为 27.5%。埃及巴贝斯虫病的流行率在牛中为 16.8%，在水牛中为 17.6%。成年动物比幼龄动物分别更容易感染巴贝斯虫 3-5 倍。雄性动物比雌性动物更容易感染巴贝斯虫，感染风险分别增加 3.7 倍和 3.5 倍。同样，有蜱虫感染的动物感染的几率是没有蜱虫感染的动物的 2-4 倍。
研究结果表明，年龄、动物性别和蜱虫感染是两种巴贝斯虫血清阳性的主要风险因素。此外，没有证据支持巴贝斯虫病的血清流行率与季节和物种相关的前提。
