Identification, typing, ecology and epidemiology of coagulase negative staphylococci associated with ruminants

• Various molecular methods for identification and typing of ruminant coagulase negative staphylococci (CNS) are now available. • Five CNS species cause the majority of CNS intramammary infections (IMI) in cows. • In an ecological framework, some CNS species can be environmental and others host-adapted. • In an epidemiological framework, some CNS IMI can be contagious and others opportunistic. • Much is yet to be learned about the ecology and...
