Quantitative phenetics and taxonomy of some phlebotomine taxa [PDF]

Memórias do Instituto Oswaldo Cruz, 1999
Elucidating the evolution of Phlebotominae is important not only to revise their taxonomy, but also to help understand the origin of the genus Leishmania and its relationship with humans. Our study is a phenetic portrayal of this history based on the genetic relationships among some New Word and Old Word taxa.

Synthesis and Evaluation of the First Generation of Glycosylated Nucleoside Analogues as Potential Inhibitors of the Base J Metabolism in Kinetoplastid Parasites

Chemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
Novel analogues of the kinetoplastid‐specific DNA base J unlock a new way to target parasite epigenetic regulation. Some compounds selectively inhibit Leishmania and Trypanosoma species without harming human cells, revealing a promising route toward innovative antiparasitic therapies.

Assessment of Leishmania exposure in blood donors from a non‐endemic urban area: A study in São Paulo

Vox Sanguinis, Volume 121, Issue 2, Page 160-168, February 2026.
Abstract Background and Objectives According to the World Health Organization, more than 1 billion people are at risk of leishmaniasis in over 89 countries. Environmental changes such as deforestation, urban expansion and climate change facilitate the spread of sand fly vectors and reservoirs, increasing disease transmission.
