Veillonella parvula is a strictly anaerobic, Gram-negative, coccus-shaped bacterium in the genus Veillonella.[2] It is a normal part of the oral flora but can be associated with diseases such as periodontitis and dental caries as well as various systemic infections, including meningitis and osteomyelitis.[3] It has also been isolated from women with bacterial vaginosis and has been associated with hypertension together with Campylobacter rectus and Prevotella melaninogenica.[4]

V. parvula is unable to feed on carbohydrates, but can feed on lactate provided by Streptococcus species also found in the oral cavity.[5] Specifically, Streptococcus mutans and V. parvula can form multispecies biofilms that lead to a lower susceptibility to antimicrobial treatments, resulting in periodontitis and dental caries.[6]

Antimicrobial susceptibility

V. parvula bacteria are susceptible to and typically treated with metronidazole and penicillin in clinical reports.[7][8][9][10] Other antibiotics that have been shown to be active against V. parvula include cephalosporin, clindamycin, and chloramphenicol.[7]

Antibiotic resistance

There have been several reports of antibiotic resistance in V. parvula isolates in different countries.[11][12][13] In Greece, V. parvula isolates were found to be somewhat resistant to penicillin, ampicillin, piperacillin/tazobactam, clindamycin, and moxifloxacin, with no reported resistance to metronidazole.[13][14] In Taiwan, V. parvula isolates were found to be resistant against metronidazole.[15] These findings represent the growing issue of antibiotic resistance worldwide.[citation needed]
