A cavitary pneumonia caused by leptotrichia species in an immunocompetent patient

Tze Shien Lo. Infect Dis Rep. .

Abstract

Leptotrichia species (LS) is an anaerobic Gram negative bacillus in the Bacteroidaceae family and part of the normal human oral flora. It is rarely pathogenic, but occasionally causes diseases in immunocompromised hosts. I am reporting a case of cavitary pneumonia caused by LS in an immunocompetent host.

Keywords: Leptotrichia sp; cavitary pneumonia; immunocompetent patient..
