Canadians Map Spread of Emerging Salmonella Dublin
Canadians Map Spread of Emerging Salmonella Dublin
Salmonella Dublin is an emerging enteric pathogen. A team of Canadian researchers finds that its emergence is being fueled partly by transmission between cattle and people, and that it has a rising rate of antimicrobial resistance. “We found that many human and cattle isolates were very closely related, and often indistinguishable, suggesting that infection may have been passed through direct contact or through the food chain” said first author Chand S. Mangat, Ph.D., a post-doctoral fellow at the Public Health Agency of Canada. The investigators used whole genome sequencing to compare their isolates with others sequenced by researchers around the world. “We found that Canadian isolates are most closely related to isolates in the USA,” said Dr. Mangat. This paper was published in Antimicrobial Agents and Chemotherapy, a journal of the American Society of Microbiology.
