a
Supplemental testing is sometimes needed to resolve overlaps. Susceptibility testing, hydrolysis, or utilization of different carbon substrates may be used. The table was compiled in part with data from previous reports (3, 9, 15).
b
=, negative reactivity; +, positive reactivity; V, variable reactivity.
c
API 20C assimilation.
d
AF, arylsulfatase.
