Gardnerella vaginalis bacteremia from pulmonary abscess in a male alcohol abuser.

A case of Gardnerella vaginalis bacteremia is reported. This bacteremia occurred in a male alcohol abuser who developed definite signs of pulmonary abscess and empyema. Streptococcus milleri grew from another blood culture, but Gardnerella vaginalis was also isolated from a bronchoscopic aspirate and pleural drainage sample as part of mixed flora containing anaerobes, Streptococcus species, Neisseria sicca, and a Haemophilus sp. We discuss the possible pathogenic character of G. vaginalis outside the genital tract from a review of the literature.
