摘要

致病细菌菌株与沙门氏菌菌株一样具有很强的适应性,可在全球范围内引起人类和其他哺乳动物的各种肠道和肠道外疾病。红肉及其制品是许多人畜共患病的重要宿主。本研究旨在调查在也门达马尔省出售的红肉(牛、绵羊和山羊)中分离出的沙门氏菌的频率、血清型和抗菌药耐药性概况。2022 年 7 月至 12 月期间,从零售商市场共采集了 250 份红肉样本。所有样本都被立即送往实验室,在选择性富集琼脂上进行亚培养,并通过血清分型和抗菌药敏感性测试(通过磁盘扩散法)进行鉴定。结果显示,250 个样本中有 26 个样本(10.4%)对沙门氏菌呈阳性反应。值得注意的是,分离出的沙门氏菌属于 10 个不同的血清型:Typhimurium 19.2%、S. Anatum 15.4%、S. Newport 11.5%、S. Enteritidis 11.5%、S. Muenchen 11.5%、S. Infantis 7.7%、S. Montevideo 7.7%、S. Dublin 7.7%、S. Senftenberg 3.9% 和 S. Arizona 3.9%。抗生素耐药性概况显示,分别有 57.5%、53.9% 和 53.9% 的分离菌株对红霉素、四环素和诺氟沙星具有耐药性。沙门氏菌的抗药性表明,沙门氏菌对健康构成重大威胁,需要采取积极的安全措施和对策。另一方面,"八月和七月 "的季节变化与沙门氏菌分离频率增加有关。

Frequency, serotyping, antibiogram, and seasonality of Salmonella isolated from red meat markets
Bacterial pathogenic strains are as adaptable as Salmonella strains and cause diverse intestinal and extraintestinal diseases in humans and other mammals worldwide. Red meat and its products are important hosts for many zoonotic diseases. This work was designed to investigate the frequency, serotypes, and antimicrobial resistance profile of isolated Salmonella spp. in red meat (cattle, sheep, and goats) sold in Dhamar Governorate, Yemen. A total of 250 red meat samples were collected from the retail seller market between July and December 2022. All samples were transported immediately to the laboratory, subcultured on selective enrichment agar, and identified by serotyping and antimicrobial susceptibility tests via disk diffusion methods. The results indicated 26 positive samples of Salmonella out of the 250 samples (10.4%). Notably, isolates belong to ten various serotypes: S. Typhimurium 19.2%, S. Anatum 15.4%, S. Newport 11.5%, S. Enteritidis 11.5%, S. Muenchen 11.5%, S. Infantis 7.7%, S. Montevideo 7.7%, S. Dublin 7.7%, S. Senftenberg 3.9%, and S. Arizona 3.9%. The antibiotic resistance profile revealed that 57.5%, 53.9%, and 53.9% of isolates are resistant to erythromycin, tetracycline, and norfloxacin, respectively. This resistance among Salmonella spp. suggests a significant threat to health, which will in turn require an active safety measure and response. On the other hand, the seasonal variations “August and July” were found to be associated with an increased frequency of Salmonella isolation.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
