Spread of antibiotic resistances through agro-food chain remains an actual question for both researchers and public health operators. Our study investigates antimicrobial resistance in Salmonella spp. strains isolated from avicultural and swine samples (prevalence: 2 % and 5, 5 % respectively). Strains belonging to different serotypes-pulsetypes have resulted multi-resistant in 76% of cases (avicultural strains: 13/23, swine strains: 73/90). Multi-drug resistant strains (MDR) have been studied for transferability by conjugation - observed in 25, 6% cases - and for genetic determinants of resistances: 73,3% MDR strains harbour plasmids; class-1 integrons have been identified in 14 strains. Comparing our findings to available scientific literature, we discuss Salmonellosis resistance pattern according to the food chain and serotype.

Abstract
Spread of antibiotic resistances through agro-food chain remains an actual question for both researchers and public health operators. Our study investigates antimicrobial resistance in Salmonella spp. strains isolated from avicultural and swine samples (prevalence: 2 % and 5, 5 % respectively). Strains belonging to different serotypes-pulsetypes have resulted multi-resistant in 76% of cases (avicultural strains: 13/23, swine strains: 73/90). Multi-drug resistant strains (MDR) have been studied for transferability by conjugation - observed in 25, 6% cases - and for genetic determinants of resistances: 73,3% MDR strains harbour plasmids; class-1 integrons have been identified in 14 strains. Comparing our findings to available scientific literature, we discuss Salmonellosis resistance pattern according to the food chain and serotype.Pubblicazioni consigliate
