Strain sharing and mobile genetic elements shape the interconnected resistomes of Campylobacter coli in Brazil.

ABSTRACT:

Background

Campylobacter coli is a ubiquitous commensal in the gut of birds and mammals. It causes acute gastroenteritis in humans when contaminated livestock meat is consumed and can be fatal in vulnerable individuals. Here, we aim to characterize the population genomic structure and antimicrobial resistance (AMR) dissemination of C. coli in Brazil contextualized against a South American background.

Results

We analyzed 32 newly sequenced short-read genomes from Brazil and 158 previously sequenced genomes from different locations in South America. Clonal complex CC828, which is known to be predominant in agriculture and human diseases, accounted for 82.4% of the Brazilian genomes (n = 108). We identified six mutations, 15 acquired genes, and one operon (cmeABC) that were ass
