Molecular epidemiology studies on reinfection versus reactivation, prevalence of multiple M. tuberculosis infections, and transmission rates among MDR and non-MDR TB
Drug-resistance studies on its prevalence and incidence various geographic regions, rapid detection of drug resistance by molecular tools, development of drug-resistance, resistance to second-line drugs, and alternative ways for TB treatment
Studies on the zoonotic aspect of bovine TB
Studies investigating social aspects of TB
These projects were conducted in collaboration with Belgian and international universities and research centers, as well as some non-governmental organizations.
