Research Interests

Mark Holmes leads a research group whose current focus of research follows their discovery of a new livestock-associated MRSA harboring a mecA homologue (now named mecC). The new MRSA was discovered during an epidemiological project milking.pnglooking at the transmission of S. aureus in dairy cows by one of our PhD students, Laura Garcia Alvarez. The original isolate was whole genome sequenced and analysed in collaboration with the Wellcome Trust Sanger Institute by Matt Holden and colleagues. We subsequently obtained funding from Defra and the MRC to investigate the discovery further. We are now undertaking studies to establish the prevalence and diversity of the new MRSA using whole genome sequencing and other techniques. In collaboration with Prof Alexander Tomasz’s lab at Rockefeller University we have recently published the results of a study into the function of the PBP2a produced by the mecC gene.

This work is funded by the BBSRC, Defra, and the MRC.

Mark Holmes is also part of a collaboration with Fernando Constantino-Casas and Murray Corke developing new evidence-based animal welfare indicators to provide a better understanding of the impact of diseases in sheep on animal welfare. This project is part of the EU funded AWIN programme which includes 10 institutes in 8 European countries, Brazil and the USA.

Mark Holmes also has interests in clinical research (including animal welfare) and evidence-based veterinary medicine and has published a number of papers and books in these areas.
