Virulence potential of Salmonella 1,4, [5],12:i:- strains isolated during decades from different sources in the Southeast region of Brazil.

ABSTRACT: Salmonella 1,4, [5],12:i:- is one of the most prevalent serovars associated with gastroenteritis in several countries, including Brazil. However, few studies have analyzed the virulence potential of this variant in this country. Therefore, this study aimed to characterize S. 1,4, [5],12:i:- strains isolated in Southeast Brazil. To this end, 113 S. 1,4, [5],12:i:- strains isolated from different sources between 1983 and 2020 were analyzed. For all strains, the frequencies of 11 virulence genes were investigated using PCR and the molecular typing was performed using pulsed-field gel electrophoresis (PFGE). Furthermore, 40 strains isolated from human and non-human sources were characterized by survival under acid and oxidative stress, and virulence analysis in Galleria mellonella was performe
