Prevalence and characterization of mecC MRSA in bovine bulk tank milk in Great Britain, 2017-18.

ABSTRACT:

Objectives

To evaluate the current prevalence status of mecC MRSA among dairy farms in England and Wales 5 years after a previous survey conducted in 2011-12.

Methods

A convenience sample of 697 dairy farms in England and Wales was used for the study, conducted in 2017-18, testing bulk tank milk samples for the presence of mecC MRSA using high salt broth enrichment and chromogenic MRSA agar selection. All putative MRSA isolates were screened by PCR for the presence of mecA and mecC genes and subjected to antimicrobial susceptibility testing using both the disc diffusion method and VITEK^® 2. MRSA isolates were also sequenced for genomic characterization.

Results

mecC MRSA were detected on 4 out of 697 dairy farms in England
