ABSTRACT

Objective: To estimate the prevalence of resistance of Mycobacterium tuberculosis to first-line antituberculosis drugs in Canada.

Methods: M. tuberculosis isolates from one third of all culture-positive tuberculosis (TB) cases diagnosed between February 1, 1993 to January 31, 1994 in Canada were collected prospectively. Proportion of drug-resistant isolates and the factors related to drug resistance were measured.

Results: Of 458 study cases, 40 (8.7%) had resistance to at least one first=line antituberculosis drug, of which 5.9% had mono-resistance, 0.7% had multidrug-resistance ...
