Abstract

This study was conducted within 2 months by sampling chicken batches from a broiler farm, a plant processing plant, and supermarket retail. The overall frequency of isolation of Salmonella was 50% (16/32), 17.5% (7/40), and 40% (4/10) for the samples collected from the broiler farm, processing plant, and retail outlet, respectively. Serovar Infantis was the predominantly isolated serovar at the 3 sampling sites. Resistance genes aac(3)IV, aph(4)Ia, bla_CTX-M65, and qacEdelta1 were detected in 84.6% (11/13) of the isolates subjected to whole genome sequencing. S. Infantis strains were clustered within and across the 3 sampling sites. This study demonstrates a direct measure of the transmission dynamics of Salmonella during a farm-to-fork approach.

特立尼达和多巴哥肉鸡生产、加工和零售中纵向恢复的沙门氏菌血清型的全基因组测序

这项研究是在两个月内通过对肉鸡农场、植物加工厂和超市零售的鸡肉批次进行抽样进行的。在肉鸡养殖场、加工厂和零售店采集的样品中，沙门氏菌的分离率分别为50%(16/32)、17.5%(7/40)和40%(4/10)。3个采样点分离的血清型主要为婴儿血清型。经全基因组测序，84.6%(11/13)的菌株检出耐药基因aac(3)IV、aph(4)Ia、blaCTX-M65和qacEdelta1。3个采样点内及采样点间均有婴幼儿链球菌聚集。这项研究证明了在农场到餐桌的方法中沙门氏菌传播动力学的直接测量。
