Direct MALDI-TOF MS identification results for 329 anaerobic bacteria according to nine most frequently identified genera in both monomicrobial (n = 250) and polymicrobial (n = 79) cultures. Not shown are results for Cutibacterium bacteria (n = 71), which were isolated only from monomicrobial cultures. Gray bars indicate percentages of bacterial identification (no. identified/no. tested) ranging from 13.3% to 97.1% in monomicrobial (light gray) and polymicrobial (dark gray) cultures, whereas white bars indicate no identification for the tested bacteria in polymicrobial cultures.
