Methicillin-Resistant Macrococcus bohemicus Encoding a Divergent SCCmecB Element
A methicillin-resistant Macrococcus isolate from canine otitis, H889678/16/1, was whole-genome sequenced using HiSeq technology to identify the species, antimicrobial resistance determinates and their genomic context. H889678/16/1 belonged to the newly described species Macrococcus bohemicus. It enc...

description | A methicillin-resistant Macrococcus isolate from canine otitis, H889678/16/1, was whole-genome sequenced using HiSeq technology to identify the species, antimicrobial resistance determinates and their genomic context. H889678/16/1 belonged to the newly described species Macrococcus bohemicus. It encoded mecB within a novel SCCmec element most similar to that of Macrococcus canis KM45013(T). This SCCmec(H889678/16/1) element also encoded blaZ(m) and fusC, but no other resistance determinates were found in the H889678/16/1 genome. The ccrA and ccrB recombinase genes within SCCmec(H889678/16/1) were distinct from those previously described in staphylococci and macrococci and therefore designated here as ccrAm3 and ccrBm3. Our study represents, to the best of our knowledge, the first description of mecB being encoded by M. bohemicus and of methicillin resistance in this species. Furthermore, the SCCmec described here is highly dissimilar to other such elements and encodes novel ccr genes. Our report demonstrates a wider distribution of mecB among Macrococcus species and expands the genomic context in which mecB may be found. The potential for dissemination of mec genes from Macrococcus to related but more pathogenic Staphylococcus species highlights the need to understand the epidemiology of these genes in macrococci. |
