Abstract

Genotypic analysis of Mycobacterium tuberculosis isolates obtained from human immunodeficiency virus type 1 (HIV-1)-seropositive (n = 80) and -seronegative (n = 25) patients from Lima, Peru, revealed two distinct genotypes correlating with the host immune status. While the level of intrastrain diversity of DNA fingerprints of HIV-seropositive isolates was less pronounced, these isolates showed many clonal groupings.
