Resumen:
Campylobacter jejuni is an important foodborne pathogen with global distribution.We describe a genotyping study of a collection of C. jejuni (n = 137) isolated from differentbroiler farms and from multiple sites along the processing line in a slaughterhouse in Argentinaduring 2011, 2012 and 2015. The isolates were genotyped using pulsed-field gel electrophoresis(PFGE) and multilocus sequence typing (MLST). Based on the PFGE results, the isolates weregrouped into 26 pulsotypes. Subsequently, the isolates representing these 26 pulsotypes werechosen for MLST genotyping, which identified 16 different sequence types (STs) and 6 clonalcomplexes (CCs) (21, 45, 48, 353, 354, 446). Several of the STs (n = 7) have not been previouslyreported in the PubMLST.org database. The most prevalent CCs were 21, 45 (both associatedwith human campylobacteriosis worldwide) and 353. This study showed high genetic diversityamong C. jejuni in the broiler production environment in Argentina with novel MLST genotypes.
