Novel Antibiotic Resistance gene in Milk
(WorldNews Switzerland)

Macrococcus caseolyticus is a harmless bacterium naturally found on the skin of dairy cows which can spread to milk during the milking process. It can also be present in dairy products made from raw milk like e.g. cheese. Researchers of the Institute of Veterinary Bacteriology of the University of Bern have identified a new methicillin resistance gene in strains of M. caseolyticus isolated from milk. Transfer of the gene to Staphylococcus aureus, a bacteria found on the skin and mucosa of animals and humans, would have dramatic consequences for public health. This methicillin resistance gene would turn this bacteria into a hazardous...
