Coagulase positive staphylococci. Enumeration in foods.
Coagulase positive staphylococci (CPS) are enumerated by
surface inoculation of decimal dilutions of a specified quantity
of the food sample on the selective agar-medium Baird-
Parker (BP) and/or Baird-Parker agar with a Rabbit-plasma
fibrinogen supplement (BP+RPF). After incubation, typical and
atypical colonies are counted. By the use of BP, a selection of
colonies must be confirmed by the coagulase test.
