背景:在蜱活动期间,Piroplasmosis和无形体病是影响牲畜的主要疾病。这些媒介传播的疾病继续在世界范围内出现,对动物健康和国民经济产生不利影响。这项研究的目的是评估Piroplasmaspp的患病率。以及它与阿尔及利亚国内反刍动物边缘无性体的共存。
方法:系统审查了三个数据库,以确定合格的研究用于最终的荟萃分析,在PRISMA声明之后。使用R软件中的“meta”软件包进行荟萃分析,并选择随机效应模型进行数据汇集。
结果:荟萃分析涵盖了19年(2004-2023年)的14篇研究论文。Theileriaspp.在所有研究中都发现了,涵盖1675头牛,190只羊,和128只山羊,产生45%的整体Theileria感染率(95%CI26-65%)。具体来说,牛的感染率为59%,而绵羊和山羊的比率分别为18%和20%,分别。巴贝西亚。在九项研究中发现,涉及1183头牛和190头羊,导致总体巴贝虫感染率为7%(95%CI4-15%),牛和羊的比率分别为10%和3%,分别。值得注意的是,八种螺旋体类动物T.annulata,T.东方神虫,T.Buffeli,T.equi,Theileriasp.,B.牛,B.bigemina,在牛身上发现了B.隐匿体,T.annulata是最普遍的,占54%。地区差异和宿主因素也影响感染率,阿尔及利亚东北部和疑似病牛的发病率较高。此外,性别,年龄,和品种影响了牛对Theileria感染的敏感性。此外,Piroplasmaspp之间存在六种不同的共感染。和A.marginale被观察到,与T.annulata/A.在六项研究中确定的边际,共同感染率为8.3%。
结论:这项分析为阿尔及利亚国内反刍动物的Piroplasmosis及其与边缘A.marginale的共同感染的现状提供了重要的见解,为监测和预防策略提供有价值的数据。
BACKGROUND: Piroplasmosis and anaplasmosis stand out as the primary diseases affecting livestock during periods of tick activity. These vector-borne diseases continue to emerge worldwide, exerting a detrimental impact on both animal health and national economies. The purpose of this study is to assess the prevalence of Piroplasma spp. and its co-occurrence with Anaplasma marginale in domestic ruminants in Algeria.
METHODS: Three databases were systematically reviewed to identify eligible studies for the final meta-analysis, following the PRISMA statement. The \'meta\' package in the R software was employed for the meta-analysis with the random effects model chosen for data pooling.
RESULTS: The meta-analysis encompasses 14 research papers spanning a 19-year period (2004-2023). Theileria spp. was identified in all studies, covering 1675 cattle, 190 sheep, and 128 goats, yielding an overall Theileria infection rate of 45% (95% CI 26-65%). Specifically, cattle had a 59% infection rate, while sheep and goats had rates of 18% and 20%, respectively. Babesia spp. was found in nine studies, involving 1183 cattle and 190 sheep, resulting in an overall Babesia infection rate of 7% (95% CI 4-15%), with cattle and sheep having rates of 10% and 3%, respectively. Notably, eight Piroplasma species T. annulata, T. orientalis, T. buffeli, T. equi, Theileria sp., B. bovis, B. bigemina, and B. occultans were detected in cattle, with T. annulata being the most prevalent at 54%. Regional disparities and host factors also impacted infection rates, with higher rates in Northeastern Algeria and among suspected disease cattle. Additionally, gender, age, and breed influenced cattle susceptibility to Theileria infection. Furthermore, six distinct co-infections between Piroplasma spp. and A. marginale were observed, with T. annulata/A. marginale identified in six studies, demonstrating an 8.3% co-infection rate.
CONCLUSIONS: This analysis offers crucial insights into the current status of Piroplasmosis and its co-infection with A. marginale in Algerian domestic ruminants, providing valuable data for surveillance and prevention strategies.
