Figure

Slow-growing, scotochromogenic Mycobacterium gordonea, showing smooth, yellow-orange pigmented colonies. The sample was cultured aerobically on 8 mL of solid Löwenstein–Jensen media for 14 days at 37°C without exposure to light. This opportunistic nontuberculous mycobacterium was isolated repeatedly from the sputum of an immunocompromised, HIV-positive patient, who had an absolute CD4 count of 1. Sample processing and culture were performed at the National Health Laboratory Service, Green Point TB-laboratory, Cape Town, South Africa. Vial size is 28 mL. Photograph courtesy of the author.
