Abortion in cattle is a major source of economic losses for the agriculture sector. It can be due to infectious or non-infectious factors. Among infectious factors, parasites, bacteria, viruses, and fungi can be involved. The present work investigated the prevalence of the main infectious agents of abortion in Algerian cattle.
Altogether 278 non-aborting and 82 aborting cows were analysed.
The prevalence ranged from 0% for to 15% for . Additionally, a case-control study was performed to find the association between the presence of the pathogens and the occurrence of abortion in cows. The odds ratios were significant for , bovine herpes virus 4, BVD virus, , Dublin, serovar Hardjo, and .
The pathogens enumerated here could be major causes of abortion among Algerian cattle.
牛流产是农业部门经济损失的主要来源。其原因可能是传染性或非传染性因素。在传染性因素中,寄生虫、细菌、病毒和真菌都可能涉及。本研究调查了阿尔及利亚牛流产主要传染原的流行情况。
共分析了278头未流产母牛和82头流产母牛。
患病率从[未提及的病原体]的0%到[未提及的病原体]的15%不等。此外,还进行了一项病例对照研究,以找出病原体的存在与母牛流产之间的关联。[未提及的病原体]、牛疱疹病毒4型、牛病毒性腹泻病毒、[未提及的病原体]、都柏林沙门氏菌、哈氏血清型牛种布鲁氏菌和[未提及的病原体]的优势比具有显著性。
此处列举的病原体可能是阿尔及利亚牛流产的主要原因。
