Genetic diversity, anti‐microbial resistance, plasmid profile and frequency of the Vi antigen in Salmonella Dublin strains isolated in Brazil

Abstract: SummarySalmonella Dublin is strongly adapted to cattle causing enteritis and/or systemic disease with high rates of mortality. However, it can be sporadically isolated from humans, usually causing serious disease, especially in patients with underlying chronic diseases.The aim of this study was to molecularly type S. Dublin strains isolated from humans and animals in Brazil to verify the diversity of these strains as well as to ascertain possible differences between strains isolated from humans and animals.

“…Similar to MLST, both methodologies grouped the strains independently of geographical, temporal, or isolation source characteristics, which reinforced the idea from previous studies of Salmonella Dublin strains from Brazil performed by our research group that suggest that these strains may have descended from a common ancestor that has little differentiated over the years [13]. In the previous study of our research group [13], the same 112 S. Dublin strains of this study were typed by pulsed-field gel electrophoresis (PFGE) and multilocus variable-number tandem repeat analysis (MLVA). Similar to the results found in the present study, PFGE also grouped the strains in a single cluster, with a similarity of ≥ 80.7%.…”

“…Salmonella Dublin is a serovar strongly adapted to bovine hosts, but can be sporadically isolated from human clinical cases [1,2]. Different molecular typing techniques have been used for epidemiological studies of S. Dublin strains worldwide [9][10][11][12][13]. The advancement in whole-genome sequencing allowed the sequencing of large sets of strains and the characterization by classic or newly developed methodologies, such as MLST and CRISPR [18,19].…”
