Background: Salmonella enterica subsp. enterica serovar Kentucky (antigenic formula 8,20:i:z6) is a serovar of the O:8 (C2-C3) serogroup. This serovar is commonly found in animals in the U.S. (Chickens, turkeys and cows), but rarely is reported in human cases. It is the most common serovar identified in non-clinical non-human, according to CDC, 2011. However, in Europe, serovar Kentucky is found in approx. 1% of the human cases. In Europe and Canada, multidrug resistant strains have been typically found. Highly A highly resistant clone of S. Kentucky (MLST type ST198), which show resistant has been widespread in Europe in travelers from Asia and Africa. This strain shows resistance to β-lactamic antibiotics, carbapenems, quinolones, aminoglycosides, co-trimoxazole (trimethoprim-sulfamethoxazole), and to azithromycin; has been widespread in Europe in travelers from East Africa. Molecular characterization shows a chromosomal genomic island carrying the resistant genes.
