Serotyping and Evaluation of Antimicrobial Resistance of Salmonella Strains Detected in Wildlife and Natural Environments in Southern Italy.

摘要: Wild animals are potential vectors of antibiotic-resistant bacteria in the environment. The present study aimed to investigate occurrence antimicrobial resistance among Salmonella serovars isolated from wildlife and environment Italy. A total 164 isolates were analyzed, six different subspecies 64 detected. High proportions proved resistant streptomycin (34.1%), followed by trimethoprim-sulfamethoxazole (23.2%), tetracycline (17.7%), ciprofloxacin (14.63%) ampicillin (11.59%). By source, lowest level was observed a water environment, while frequent strains collected shellfish, reptiles birds. Multidrug-resistant recovered seafood (n = 11), mammals 3) 1). Three S. Typhimurium monophasic variant showed asimultaneous ampicillin, streptomycin, trimethoprim-sulfamethoxazole, which represents recognized alert profile for this serovar. These data indicate environmental dissemination due anthropogenic activities, which, southern Italy, probably have higher impact on marine ecosystems than terrestrial ones. Moreover, as most considered usually consumed humans, presence them is matter great concern.
