Epidemiology of Nontuberculous Mycobacteria in Patients without HIV Infection, New York City
|NTM species*||No. positive cultures||Adequate data to assess case status†||No. patients with disease (%)‡|
|All species||505||375||119 (32)|
|Mycobacterium avium (MAC) complex||422||297||79 (27)|
|Rapidly growing mycobacteria‡||45||41||25 (61)|
|M. abscessus||14||13||11 (85)|
|M. chelonae||15||13||4 (31)|
|M. fortuitum||16||15||10 (67)|
|M. kansasii ‡||12||10||7 (70)|
|M. marinum ‡||4||4||4 (100)|
|M. xenopi||13||9||5 (56)|
*M. flavescens, M. gastri, M. haemophilum, and M. neoaurum were isolated once each.
†Patients with adequate clinical, radiographic, and mycobacteriologic data to assess case status.
‡Greater proportion of rapidly growing mycobacteria, M. kansasii, and M. marinum caused nontuberculous mycobacteria (NTM) disease when compared with MAC (p<0.01).
