a
Vagina, vaginal-rectal sample.
b
Subsequent MALDI-TOF MS identification scores of all available S. pseudoporcinus isolates (except isolates 1, 7, 8, and 33) were improved with the addition of more MSP entries to the library database.
c
NA, isolate not available; NP, not performed.
d
STN, Streptococcus nontypeable.
e
S, susceptible; R, resistant.
