Impact of collaborative actions of Leishmania (Viannia) braziliensis subpopulations on the infection profile. [PDF]

Parasitology, 2022
Abstract This study focuses on the role of the population structure of Leishmania spp. on the adaptive capacity of the parasite. Herein, we investigate the contribution of subpopulations of the L. (V.) braziliensis Thor strain (Thor03, Thor10 and Thor22)
