Research Group Coordinator – Isabel Couto
The main aim of the THOP Research Group is the analysis of the molecular epidemiology, drug-resistance mechanisms and the development of new drugs and diagnostic methods for tuberculosis, HIV and opportunistic diseases, in a Global Health context.
In 2023 we continued our work on the analysis of resistance to antibacterials and antiretrovirals as well as the molecular characterization of the main lineages of opportunistic, emerging and reemerging pathogens. We enlarged our studies and efforts on establishing antimicrobial susceptibility testing breakpoints for mycobacteria, now focusing on non-tuberculous mycobacteria. We also continued the recently established research on drug repositioning for multidrug resistant infections, metavirome analysis of wastewaters and study of SARS-CoV-2 variants to advance response to epidemics. Other areas of work include resistance to antiretrovirals and the molecular epidemiology of several opportunistic pathogens.
