Salmonella Dublin

Thursday, September 28, 2017

(NY) Salmonella Dublin: Since 9/1/17, Salmonella Group D1 (presumptive Salmonella Dublin) has been isolated from 12 different dairy farms in New York State. For two of the farms, this was the first detection. For the remainder, Salmonella Dublin has been previously detected and these new cases are evidence of persistence and ongoing clinical challenges due to Salmonella Dublin. Serotyping is pending to confirm that the recent Salmonella D1 isolates are Salmonella Dublin. Detection was primarily in young calves ranging from 4 days to 3 months in age, with a single isolate from a fecal sample of a first lactation cow. All NYS isolates in recent years exhibit a severely multi-drug resistant antimicrobial susceptibility pattern.
