Abstract

We investigated the possibilities of the MALDI-TOF MS for species identification of anaerobic gram-negative cocci isolated from clinical specimens of cancer patients. A total 70 Veillonella clinical isolates and one Acidaminococcus intestini isolate were analysed by the Bruker Microflex MALDI-TOF instrument with the Biotyper 3, 0 software. All isolates were identified to the species level with a scores greater than 1.9. The most common species were V. parvula (37 strains), then followed by decreasing the frequency V. dispar (16), V. atypica (16) and V. denticariosi (1). Susceptibilities of the isolates were determined by the E-test methodology. All Veillonella isolates were susceptible to imipenem, whereas a high resistance rates were observed for penicillin G, amoxicillin/clavulanate and metronidazole. The proportion of intermediate/resistant isolates of V. parvula, V. dispar and V. atypica to penicillin (MIC ≥ 1 µg/ml) was 86%, 85% and 100%, respectively. The resistance to amoxicillin/clavulanate (MIC 16 - 32 µg/ml) was observed in about 28,6% V. parvula isolates, 23,1% V. dispar isolates and 6,7% V. atypica isolates. According to EUCAST criteria, resistance to metronidazole (MIC ≥ 8 µg/ml) of V. parvula, V. dispar and V. atypica was 88,6%, 53,8% and 40%, respectively.
