Conventional and molecular epidemiology of tuberculosis in Manitoba.

Background: To describe the demographic and geographic distribution of tuberculosis (TB) in Manitoba, thus determining risk factors associated with clustering and higher incidence rates in distinct subpopulations.

Methods: Data from the Manitoba TB Registry was compiled to generate a database on 855 patients with tuberculosis and their contacts from 1992-1999. Recovered isolates of M.

Epidemiology and clinical spectrum of blastomycosis diagnosed at Manitoba hospitals.
