Factors Associated With the Emergence and Spread of Visceral Leishmaniasis in the State of São Paulo, Brazil

Zoonoses and Public Health, Volume 73, Issue 4, Page 348-357, June 2026.
ABSTRACT Introduction Visceral leishmaniasis (VL), once considered a rural disease in Brazil, has progressively urbanised, particularly in the state of São Paulo (SSP), where the first urban cases emerged after the detection of the vector Lutzomyia longipalpis in 1997.

The Leishmania donovani complex: genotypes of five metabolic enzymes (ICD, ME, MPI, G6PDH, and FH), new targets for multilocus sequence typing.

, 2007
Flagellates of the Leishmania donovani complex are causative agents of human cutaneous and visceral leishmaniasis. The complex is comprised of L. donovani, Leishmania infantum and Leishmania archibaldi, although the latter is not now considered to be a ...

Proteophosophoglycans regurgitated by Leishmania-infected sand flies target the L-arginine metabolism of host macrophages to promote parasite survival [PDF]

, 2009
All natural Leishmania infections start in the skin; however, little is known of the contribution made by the sand fly vector to the earliest events in mammalian infection, especially in inflamed skin that can rapidly kill invading parasites.

Elevated baseline expression of seven virulence factor RNA transcripts in visceralizing species of : a preliminary quantitative PCR study

Therapeutic Advances in Infectious Disease, 2022
Introduction: Leishmaniasis is a neglected tropical disease that manifests as three major disease phenotypes: cutaneous, mucocutaneous, and visceral. In this preliminary study, we quantified virulence factor (VF) RNA transcript expression in Leishmania ...

Lipophosphoglycan 3 From Binds Heparin With Micromolar Affinity

Bioinformatics and Biology Insights, 2018
Leishmania infantum chagasi is an intracellular protozoan parasite responsible for visceral leishmaniasis, a fatal disease in humans. Heparin-binding proteins (HBPs) are proteins that bind to carbohydrates present in glycoproteins or glycolipids ...

Impact of LbSapSal Vaccine in Canine Immunological and Parasitological Features before and after Leishmania chagasi-Challenge.

PLoS ONE, 2016
Dogs represent the most important domestic reservoir of L. chagasi (syn. L. infantum). A vaccine against canine visceral leishmaniasis (CVL) would be an important tool for decreasing the anxiety related to possible L.

Macrophage Polarization in the Skin Lesion Caused by Neotropical Species of Leishmania sp

Journal of Immunology Research, 2021
Macrophages play important roles in the innate and acquired immune responses against Leishmania parasites. Depending on the subset and activation status, macrophages may eliminate intracellular parasites; however, these host cells also can offer a safe ...

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
