Abstract

The spread of multidrug resistant (MDR) Salmonella strains, along the poultry supply chain, can represent a relevant threat to human health. This study aimed to evaluate the prevalence and antimicrobial resistance of Salmonella spp. isolated from poultry meat for human consumption. Between 2019 and 2021, 145 samples were analyzed according to ISO 6579-1:2017. The strains isolated were identified by using biochemical-enzymatic assays and serotyping, according to the Kauffmann-White-Le Minor scheme. The antibiotic susceptibility tests were determined using the Kirby-Bauer method. Forty Salmonella spp. strains were isolated and serotyping showed Salmonella Infantis to be predominant. 80% of the isolated strains were MDR and identified as S. Infantis. This study confirms the circulation of MDR Salmonella isolated from poultry meat and highlights the predominance of the S. Infantis serovar, which represents an emerging risk factor under the One Health holistic approach.

家禽肉中沙门氏菌的流行及耐药性分析。

耐多药沙门氏菌菌株在家禽供应链上的传播可能对人类健康构成相关威胁。本研究旨在评估从人类食用禽肉中分离的沙门氏菌的流行情况和耐药性。在2019年至2021年期间，145个样本根据ISO 6579-1:2017进行了分析。根据Kauffmann-White-Le Minor方案，采用生化酶测定和血清分型对分离的菌株进行鉴定。药敏试验采用Kirby-Bauer法。分离到40株沙门菌，血清分型显示以婴儿沙门菌为主。80%的分离菌株为耐多药菌株，鉴定为婴儿链球菌。这项研究证实了从禽肉中分离出的耐多药沙门氏菌的流通，并强调了婴儿链球菌血清型的优势，这代表了“同一个健康”整体方法下的一个新兴风险因素。
