Evaluation of a Multilocus Sequence Typing (MLST) scheme for Leishmania (Viannia) braziliensis and Leishmania (Viannia) panamensis in Colombia

Parasites & Vectors, 2017
Leishmaniases are parasitic vector-borne diseases affecting more than 12 million people in 98 countries. In Colombia, leishmaniasis is widespread and the most common clinical manifestation is cutaneous, mainly caused by L. panamensis and L. braziliensis. Currently, the genetic diversity of these species in Colombia is unknown.

Canine Leishmaniasis in Rio de Janeiro, Brazil (2000–2015): Taxonomic Characterisation of Etiological Agents and Geospatial Case Analysis

Zoonoses and Public Health, Volume 73, Issue 4, Page 314-325, June 2026.
ABSTRACT Introduction Canine Leishmaniasis is a vector‐borne zoonotic disease caused by several species of protozoa of the genus Leishmania. In the state of Rio de Janeiro (RJ), Leishmania braziliensis is the most prevalent species causing tegumentary leishmaniasis (TL) and Leishmania infantum is the main causative agent of visceral leishmaniasis (VL).

Tegumentary Leishmaniasis Associated With Immune Reconstitution in an HIV Patient—A Case Report

Parasite Immunology, Volume 48, Issue 5, May 2026.
ABSTRACT HIV‐associated Immune Reconstitution Inflammatory Syndrome (IRIS) may significantly alter the immunopathological presentation of American Tegumentary Leishmaniasis (ATL), occasionally causing paradoxical clinical exacerbations. We report the long‐term follow‐up of a 39‐year‐old female coinfected with HIV and disseminated mucocutaneous ...

Sex in Immune Cells and Parasitic Diseases — A Complex Relationship

Immunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Epidemiological studies consistently show that many parasitic diseases affect males more frequently than females. These disparities are multifactorial, arising partly from gender‐specific behaviors that influence exposure risk and health‐seeking practices, especially in low‐ and middle‐income countries. Increasing evidence also highlights that

Experimental infection with Leishmania (Viannia) braziliensis, and Leishmania (Leishmania) amazonensis in the marmoset, Callithrix penicillata (Primates: Callithricidae) [PDF]

Memórias do Instituto Oswaldo Cruz, 1990
Fourteen marmosets (Callithrix penicillata) were inoculated intradermally with promastigotes and/or amastigotes of Leishmania (Viannia) braziliensis (L. (V) b.) strains MHOM/BR/83/LTB-300 MHOM/BR/85/LTB-12 MHOM/BR/81/LTB-179 and MHOM/BR/82/LTB-250. The evolution of subsequent lesions was studied for 15 to 75 weeks post-inoculation (PI).

Leishmaniasis Transmission Risk at the Forest‐Peridomestic Interface in an Area of Southern Sinaloa, Mexico: Entomological, Molecular, and Climatic Evidence

Journal of Parasitology Research, Volume 2026, Issue 1, 2026.
Leishmaniasis, caused by Leishmania spp. and transmitted by phlebotomine sand flies, affects almost 1,000,000 people annually across more than 90 countries. In Mexico, growing evidence of locally acquired transmission in northwestern states makes ecoepidemiological work increasingly urgent.

Evidence Gaps and Global Patterns in Leishmaniasis Control: A Scoping Review of Clinical, Diagnostic, and Treatment Strategies

Journal of Parasitology Research, Volume 2026, Issue 1, 2026.
Background Leishmaniasis is a neglected tropical disease with diverse clinical forms, heterogeneous geographical distribution, and persistent diagnostic and treatment challenges. Although substantial primary research exists, evidence remains fragmented, limiting integrated and context‐specific control strategies.
