present in feces of food animals may contaminate their meats and act as a potential source of infection (CDI) to humans. resistance to antibiotics, its production of toxins and spores play major roles in the pathogenesis of CDI. This is the first study to evaluate prevalence in retail raw animal meats, its antibiotics susceptibilities and toxigenic activities in Al-Jouf, Saudi Arabia. Totally, 240 meat samples were tested. was identified by standard microbiological and biochemical methods. Vitek-2 compact system confirmed isolates were 15/240 (6.3%). Toxins A/B were not detected by Xpect toxin A/B tests. Although all isolates were susceptible to vancomycin and metronidazole, variable degrees of reduced susceptibilities to moxifloxacin, clindamycin or tetracycline antibiotics were detected by Epsilon tests. strains with reduced susceptibility to antibiotics should be investigated. Variability between the worldwide reported contamination levels could be due to absence of a gold standard procedure for its isolation. Establishment of a unified testing algorithm for detection in food products is definitely essential to evaluate the inter-regional variation in its prevalence on national and international levels. Proper use of antimicrobials during animal husbandry is crucial to control the selective drug pressure on strains associated with food animals. Investigating the protective or pathogenic potential of non-toxigenic strains and the possibility of gene transfer from certain toxigenic/ antibiotics-resistant to non-toxigenic/antibiotics-sensitive strains, respectively, should be worthy of attention.
食用动物粪便中存在的[某种物质]可能会污染它们的肉类,并成为人类潜在的感染源(艰难梭菌感染,CDI)。[该物质]对抗生素的耐药性、其毒素和孢子的产生在艰难梭菌感染的发病机制中起主要作用。这是第一项评估沙特阿拉伯朱夫地区零售生动物肉中[该物质]的流行情况、其抗生素敏感性和产毒活性的研究。总共检测了240份肉类样本。通过标准微生物学和生化方法鉴定[该物质]。Vitek-2紧凑型系统确认[该物质]分离株为15/240(6.3%)。通过Xpect毒素A/B检测未检测到毒素A/B。尽管所有分离株对万古霉素和甲硝唑敏感,但通过Epsilon检测发现对莫西沙星、克林霉素或四环素类抗生素存在不同程度的敏感性降低。对抗生素敏感性降低的[该物质]菌株应进行调查。全球报告的[该物质]污染水平之间的差异可能是由于缺乏分离它的金标准程序。建立统一的食品中[该物质]检测算法对于评估其在国家和国际层面的区域间流行差异绝对至关重要。畜牧业中正确使用抗菌药物对于控制与食用动物相关的[该物质]菌株的选择性药物压力至关重要。分别研究非产毒[该物质]菌株的保护或致病潜力以及某些产毒/耐药菌株向非产毒/敏感菌株基因转移的可能性值得关注。
