The frequency of chromosomal aberrations and sister chromatid exchanges (SCEs) were estimated in the lymphocytes of 95 untreated tuberculosis patients to evaluate the chromosomal damage with reference to bacterial invasion. The frequency of chromosomal aberrations was significantly higher in tuberculosis patients compared to controls (p < 0.001) while the SCE frequency did not show any statistically significant differences. These findings indicate that the basic mechanism of formation of chromosomal aberrations and SCE are different and they suggest that the tubercle bacillus might be capable of inducing chromosome damage.
