Abstract

ABSTRACT: N/A Laboratory culture results, dating back to 1960, were reviewed at the Veterans Administration Medical Center in Oklahoma City. Nontuberculous mycobacterial incidence increased substantially during the 21-year period as tuberculosis incidence decreased. Nontuberculous mycobacteria were found to represent 13.7% of all mycobacterial isolates, with Mycobacterium kansasii and M intracellulare-avium complex the predominant species. When the dates of first positive cultures were evaluated, a significant month-to-month variation was found in M tuberculosis but not nontuberculous mycobacteria, suggesting a different mode of transmission for the two. There was no significant difference in the racial distribution or age of individuals with nontuberculous mycobacteria.
