Background: Salmonella enterica subsp. enterica serovar Infantis (antigenic formula 6,7,14:r:1,5) is a serovar of the O:7 (C1) serogroup. S. Infantis is commonly found in chickens and broiler flocks. In addition, outbreaks caused by S. Infantis have been associated with pet food and treats. In European countries, a multidrug-resistant (MDR) strain of S. Infantis was disseminated; this strain emerged from broilers in Hungary (Hungarian clone of S. Infantis). Resistant pattern of this Hungarian clone included resistance to: nalidixic acid, streptomycin, sulphonamide, and tetracycline. In Italy, an MDR strain of S. Infantis that showed resistance to ampicillin, chloramphenicol, streptomycin, sulphonamide, tetracycline, kanamycin and trimethoprim/sulfamethoxazole emerged in 2005-06.
