Abstract

The purpose of the study is to identify and isolate the causative agent of Salmonella sheep abortion in the sheep breeding industry of the Republic of Kazakhstan. The study aims to provide a basis for the development and testing of vaccines against salmonella sheep abortion using the isolated epizootic strains of Salmonella abortus-ovis AN 9/2 and Salmonella abortus-ovis 372 as control strains for immunogenicity testing. Biomaterials and pathologic materials were investigated of 114 abortions, dead ewes, and newborn lambs using the bacteriological method with the diagnostic purpose from 2009 to 2019. As a result of the bacteriological studies, the causative agent of salmonella sheep abortion was isolated and identified - Salmonella abortus-ovis. The study concludes that salmonella sheep abortion is a significant infectious disease that can cause massive economic losses and high mortality rates in sheep breeding. Prevention and control measures, such as regular cleaning, disinfection of premises, clinical examination, and thermometry of lambs, bacteriological studies, and vaccination against salmonella sheep abortion, are essential in reducing the incidence of the disease and increasing animal productivity.

沙门氏菌羊流产:分布、诊断和控制措施。

本研究的目的是鉴定和分离哈萨克斯坦共和国绵羊养殖业中的沙门氏菌羊流产病原体。本研究旨在以羊流产沙门菌AN 9/2和羊流产沙门菌372分离株为对照株进行羊流产沙门菌免疫原性试验，为研制和检测羊流产沙门菌疫苗提供依据。采用细菌学方法对2009 - 2019年114例流产、死母羊和新生羔羊的生物材料和病理材料进行研究，并进行诊断。通过细菌学研究，分离鉴定了羊流产沙门氏菌的病原——流产-卵沙门氏菌。该研究得出结论，沙门氏菌羊流产是一种重要的传染病，可以造成巨大的经济损失和绵羊养殖的高死亡率。预防和控制措施，如定期清洁、场所消毒、临床检查和羔羊体温测量、细菌学研究以及接种沙门氏菌羊流产疫苗，对于减少疾病发病率和提高动物生产力至关重要。

期刊介绍： Journal of Applied Animal Welfare Science (JAAWS) publishes articles on methods of experimentation, husbandry, and care that demonstrably enhance the welfare of nonhuman animals in various settings. For administrative purposes, manuscripts are categorized into the following four content areas: welfare issues arising in laboratory, farm, companion animal, and wildlife/zoo settings. Manuscripts of up to 7,000 words are accepted that present new empirical data or a reevaluation of available data, conceptual or theoretical analysis, or demonstrations relating to some issue of animal welfare science. JAAWS also publishes brief research reports of up to 3,500 words that consist of (1) pilot studies, (2) descriptions of innovative practices, (3) studies of interest to a particular region, or (4) studies done by scholars who are new to the field or new to academic publishing. In addition, JAAWS publishes book reviews and literature reviews by invitation only.
