food-borne infections are a serious public health problem. In Benin, there is a proliferation of pork consumption in several forms. This study aims to determine the prevalence and the antimicrobial resistance of strains isolated from pig guts, pig feces, and surface swabs from the cutting tables in southern Benin. For this purpose, 200 samples of pig guts, 40 samples of swabs from the cutting table surface, and 8 samples of pig feces were collected and subjected to bacteriological examination. The method used for the identification of bacteria was microbiological culture combined with molecular identification by PCR. The identified strains were then subjected to antibiotic susceptibility testing according to the methodology recommended by the EUCAST. Antibiotic profiles were compared between strains isolated from pig guts, pig feces, and cutting table surfaces on the one hand and among the different sampling sites on the other hand. The results obtained show that 47.6% of the samples analyzed were contaminated by spp. Molecular identification revealed 34.7% of and 9.3% of . The study of antimicrobial susceptibility showed resistance to ciprofloxacin, 44% to ampicillin, 23.9% to erythromycin, 11% to gentamicin, and 10.1% to amoxicillin + clavulanic acid. In total, 90.8% of the isolated strains were multidrug resistant. The use of antimicrobials in livestock production systems has increased considerably, which could explain, at least partially, the prevalence of and the resistance of strains to antibiotics. To limit the risk of food-borne infections, it is therefore important to include in the list of pathogens to be tested during sanitary quality control of meat and meat products in Benin.
食源性感染是一个严重的公共卫生问题。在贝宁,多种形式的猪肉消费呈增长态势。本研究旨在确定从贝宁南部猪肠道、猪粪便以及屠宰台表面拭子中分离出的菌株的流行情况和抗菌药物耐药性。为此,收集了200份猪肠道样本、40份屠宰台表面拭子样本和8份猪粪便样本,并进行细菌学检查。用于细菌鉴定的方法是微生物培养结合PCR分子鉴定。然后根据欧盟药敏试验委员会推荐的方法对鉴定出的菌株进行抗生素敏感性测试。一方面比较从猪肠道、猪粪便和屠宰台表面分离出的菌株之间的抗生素谱,另一方面比较不同采样地点之间的抗生素谱。获得的结果表明,47.6%的分析样本被[具体菌名]污染。分子鉴定显示[具体菌名1]占34.7%,[具体菌名2]占9.3%。抗菌药物敏感性研究表明,对环丙沙星耐药的占44%,对氨苄西林耐药的占23.9%,对红霉素耐药的占11%,对庆大霉素耐药的占10.1%,对阿莫西林+克拉维酸耐药的占10.1%。总共90.8%的分离[具体菌名]菌株对多种药物耐药。畜牧生产系统中抗菌药物的使用大幅增加,这至少可以部分解释[具体菌名]的流行情况以及菌株对抗生素的耐药性。因此,为了限制食源性感染的风险,将[具体菌名]列入贝宁肉类和肉类产品卫生质量控制期间要检测的病原体清单中很重要。
