Typing of mecD Islands in Genetically Diverse Methicillin-Resistant Macrococcus caseolyticus Strains from Cattle.

ABSTRACT: Macrococcus caseolyticus belongs to the normal bacterial flora of dairy cows and does not usually cause disease. However, methicillin-resistant M. caseolyticus strains were isolated from bovine mastitis milk. These bacteria had acquired a chromosomal island (McRI _mecD -1 or McRI _mecD -2) carrying the methicillin resistance gene mecD To gain insight into the distribution of McRI _mecD types in M. caseolyticus from cattle, 33 mecD-containing strains from Switzerland were characterized using molecular techniques, including multilocus sequence typing, antibiotic resistance gene identification, and PCR-based McRI _mecD typing. In addition, the same genetic features were analyzed in 27 mec
