a
Isolates that were typeable by coagglutination tests with typing sera but nontypeable (NT) by cps typing PCR assays.
b
Nonserotypeable isolates, include autoagglutinating, multiagglutinating, and nonagglutinating strains.
c
Isolates that were typeable by cps typing PCR assays but not by the coagglutination test.
d
Isolates that were nontypeable by either coagglutination tests or cps typing PCR assays.
