Microbiological Description -- Oligoarthritis and Localized Swellings


The direct acid fast stain on the wrist tissue was negative, however the culture from left wrist and left distal ulna grew acid-fast bacilli, which were identified as Mycobacterium Tuberculosis. Susceptibility testing demonstrated susceptibility to Streptomycin, Isoniazid, Rifampin, Ethambutol, and Pyrazinamide. No other microorganisms were isolated from the specimens. Sputum cultures were negative for mycobacteria. When the results of the cultures of the wrist were known, a urine culture was performed. The urine culture also grew Mycobacterium Tuberculosis. At the time of orchiectomy the testicular lesion was thought to be malignant in origin and was not submitted for culture.
