Zusammenfassung:is a leading foodborne pathogen, and poultry are a major vehicle for infection. Houseflies play important roles in colonization of broiler flocks with but comparable information for turkey farms is limited. Here, we investigated houseflies as potential vectors for in 28 commercial turkey flocks. We characterized species, genotypes, and the antimicrobial resistance (AMR) profiles of from turkey feces and houseflies in the same turkey house. Of the 28 flocks, 25 yielded from turkey droppings and houseflies, with an average of 6.25 and 3.11 log CFU/g feces and log CFU/fly, respectively. Three flocks were negative for both in turkey feces and in houseflies. Both and were detected in turkey feces and houseflies, with more likely to be recovered from houseflies than feces. Determination of species, genotypes, and AMR profiles revealed up to six different strains in houseflies from a single house, including multidrug-resistant strains. For the predominant strain types, presence in houseflies was predictive of presence in feces, and vice versa. These findings suggest that houseflies may serve as vehicles for dissemination of , including multidrug-resistant strains, within a turkey house, and potentially between different turkey houses and farms in the same region.
