Salmonella enterica serovar Heidelberg (S. Heidelberg) is a zoonotic, ubiquitous, and worldwide-distributed pathogen, responsible for gastroenteritis in humans caused by the consumption of contaminated food. In this study, 11 S.

Genomic characterization and antimicrobial resistance profiles of Salmonella enterica serovar Infantis isolated from food, humans and veterinary-related sources in Brazil.

Aims: To characterize the genetic relatedness, phenotypic and genotypic antimicrobial resistance and plasmid content of 80 Salmonella Infantis strains isolated from food, humans and veterinary sources from 2013 to 2018 in Brazil.

Methods And Results: Pulsed-field gel electrophoresis and single-nucleotide polymorphism analysis showed major clusters containing 50% and 38.8% of the strains studied respectively.

Analysis of the antimicrobial resistance gene frequency in whole-genome sequenced from Latin American countries.

species are important environmental-related bacteria responsible for diverse infections in humans due to consumption of contaminated water and seafood in underdeveloped areas of the world. This study aimed to investigate the frequency of antimicrobial resistance genes in 577 sequenced and strains isolated in Latin American countries available at the NCBI Pathogen Detection database and to determine the sequence type (ST) of the strains. Almost all strains studied (99.

Salmonella Typhimurium ST313 isolated in Brazil revealed to be more invasive and inflammatory in murine colon compared to ST19 strains.

Salmonella Typhimurium (ST313) has caused an epidemic of invasive disease in sub-Saharan Africa and has been recently identified in Brazil. As the virulence of this ST is poorly understood, the present study aimed to (i) perform the RNA-seq in vitro of S. Typhimurium STm30 (ST313) grown in Luria-Bertani medium at 37°C; (ii) compare it with the RNA-seq of the S.

Draft Genome Sequences of 80 Salmonella enterica Serovar Infantis Strains Isolated from Food, Environmental, Human, and Veterinary Sources in Brazil.

Phenotypic and genotypic characterization of Salmonella Typhimurium isolates from humans and foods in Brazil.

Salmonella enterica subsp. enterica serovar Typhimurium (S. Typhimurium) causes gastroenteritis in many countries.

Virulence traits and expression of bstA, fliC and sopE2 in Salmonella Dublin strains isolated from humans and animals in Brazil.

Salmonella Dublin is a strongly cattle-adapted serovar that has also been responsible for severe invasive infections in humans. Although invasive infections by non-typhoid Salmonella have increased in developed and in developing countries, in sub-Saharan Africa these infections have been frequently related to Salmonella Typhimurium strains from Sequence Type (ST) 313 that harbor a possible virulence marker, the bstA gene, broadly detected in S. Dublin strains.

Analysis of Resistance Gene Prevalence in Whole-Genome Sequenced from Brazil.

is an order of bacteria responsible for community and hospital-acquired infections related to high rates of antimicrobial resistance and increased treatment costs, morbidity, and mortality globally. The aims of this study were to analyze the frequency of the resistance genes detected and distribution over the years and sources of isolation in sequenced strains isolated in Brazil and available at the Pathogen Detection website. The presence of resistance genes was analyzed in 1,507 whole-genome sequenced strains of 19 species.
