摘要: In this study, water samples were analyzed from a rural area of North Carolina after Hurricane Florence in 2018 and the distribution ttrC virulence gene Salmonella enterica investigated. We also examined culturable S. determined their antibiotic resistance profiles. Antibiotic genes (ARGs) classes aminoglycoside, beta-lactam, macrolide-lincosamide-streptogramin B (MLSB) targeted study. The was detected 23 out 25 locations. There wider higher range flooded versus unflooded (0-2.12 × 105 copies/L vs. 0-4.86 104 copies/L). Culturable isolated 10 sampling locations, which less prevalent than gene. profiles not distinct among isolates. aminoglycoside aac(6')-Iy had highest relative abundance (around 0.05 copies/16S rRNA copy all isolates) ARGs. These findings suggested that flooding event led to numbers some bodies compared those bodies. high ARG level similar observed isolates both samples, suggesting within region, regardless flooding.
