Total Ortholog Median Matrix as an alternative unsupervised approach for phylogenomics based on evolutionary distance between protein coding genes

Scientific Reports, 2021
The increasing number of available genomic data allowed the development of phylogenomic analytical tools. Current methods compile information from single gene phylogenies, whether based on topologies or multiple sequence alignments.

Glutathione reductase-catalyzed cascade of redox reactions to bioactivate potent antimalarial 1,4-naphthoquinones--a new strategy to combat malarial parasites. [PDF]

, 2011
Our work on targeting redox equilibria of malarial parasites propagating in red blood cells has led to the selection of six 1,4-naphthoquinones, which are active at nanomolar concentrations against the human pathogen Plasmodium falciparum in culture and ...

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).

Serosurveillance of Leishmania infantum in Zoo‐Kept Animals in Spain

Zoonoses and Public Health, Volume 73, Issue 1, Page 65-73, February 2026.
ABSTRACT Introduction Leishmaniosis is a sand fly‐borne zoonosis mainly caused by Leishmania infantum in Europe. Exposure to this protozoan has been widely reported in many domestic and wild species. However, epidemiological surveys evaluating the circulation of L. infantum in zoo‐kept animals remain limited. This large‐scale study aims to evaluate the

Vectors of Trypanosomatids (Kinetoplastida: Trypanosomatidae) in Tabatinga, Amazonas, Brazil

Acta Brasiliensis, 2017
The sand flies transmit diseases to humans and animals, such as arboviruses and bartonellosis, besides the leishmaniasis. The objective of this research was identified potential vectors of this disease in the municipality of Tabatinga.

Genome sequencing project has begun on two plant trypanosomatids (Phytomonas) [PDF]

, 2010
Some trypanosomatids are responsible for wilt in tropical crops, such as hartrot disease in the coconut palm. They have a major economic impact in Latin America and the Caribbean.

Identification of internalin-A-like virulent proteins in Leishmania donovani [PDF]

, 2016
Background An active immune surveillance and a range of barriers to infection allow the host to effectively eliminate microbial pathogens. However, pathogens may use diverse strategies to subdue such host defences. For instance, one such mechanism is the

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
