The following question was posted:
"I would like to know if S.aureus belongs to any serumtype.
I think that the question is negative, but I'm not sure.
I will be very pleased if anyone have information."
The short answer is yes, S. aureus strains do have serotypes. For
example most (about 75-80%) nosocomial MRSA strains are type 5 or
type 8 (based on their capsular polysaccharides). Serotypes have
also been defined for different lysogenic bacteriophage, and
different exopropteins (like the exfoliative toxins).
