Genome Analysis of Triploid Hybrid Leishmania Parasite from the Neotropics

Emerging Infectious Diseases, 2023
We discovered a hybrid Leishmania parasite in Costa Rica that is genetically similar to hybrids from Panama. Genome analyses demonstrated the hybrid is triploid and identified L. braziliensis and L. guyanensis–related strains as parents.

Plasticity of gp63 gene organization in Leishmania (Viannia) braziliensis and Leishmania (Viannia) peruviana

Parasitology, 1995
SUMMARYThe genomic organization of gp63 genes in 4 and 7 isolates of Leishmania braziliensis and L. peruviana, respectively was studied by RFLP analysis with 3 restriction enzymes (Bgl I, Sal I and Apa I). Our results showed a marked polymorphism among isolates. Some characters were specific to L. braziliensis or to L. peruviana, and others specific to

Susceptibility to Miltefosine in Brazilian Clinical Isolates of Leishmania (Viannia) braziliensis [PDF]

The American Society of Tropical Medicine and Hygiene, 2017
Leishmania (Viannia) braziliensis is the main causative species of tegumentary leishmaniasis in Brazil. In this study, we evaluated the susceptibility of 16 clinical isolates of L. (V.) braziliensis from different regions of Brazil to miltefosine in vitro.

Multiple hybrid genotypes of Leishmania (viannia) in a focus of mucocutaneous Leishmaniasis. [PDF]

, 2007
The principal agent of mucocutaneous leishmaniasis (MCL) is the South American protozoan parasite Leishmania (Viannia) braziliensis. This organism is generally considered to be clonal, that is, it does not to undergo genetic exchange.

Energetic metabolism of axenic promastigotes of Leishmania (Viannia) braziliensis

Experimental Parasitology, 2011
Leishmania spp are protozoans capable of carbohydrates degradation and as energy source they can use glucose, aminoacids or lipids from the environment. The products of the metabolic pathways such as organic acids may be used as an index of their energetic metabolic profile.
