Gordona terrae central nervous system infection in an immunocompetent patient

The bacterial genus Gordona includes seven species of mycolic acid-containing actinomycetes which are cultured from environmental sources and rarely from clinical samples. They have been implicated in primary pulmonary diseases, nosocomial wound infections, and central nervous system infections in two immunocompromised patients. We isolated Gordona terrae from the cerebrospinal fluid sample of an immunocompetent patient with meningitis and multiple brain abscesses and detected Gordona terrae DNA in the abscesses. The outcome was good at the 4-year follow-up, after prolonged treatment with trimethoprim-sulfamethoxazole. Phenotypic identification of this isolate was confirmed by analysis of the 16S rRNA gene sequence, which shared 100% homology with that of G. terrae reference strains. Physicians and clinical microbiologists must be aware of the occurrence of Gordona species infection not only among immunocompromised patients but among all patients. Accurate identification of Gordona species may be accomplished by molecular techniques.
