The 245 kb amplified chromosome of Leishmania (V.) braziliensis contains a biopterin transporter gene

Memorias do Instituto Oswaldo Cruz, 2003
Leishmania (V.) braziliensis M2903 presents a small linear and stable 245 kb chromosome originating from a genomic amplification. Similar amplifications present in other species of Leishmania contain a gene coding for a biopterin transporter.

Mechanisms of Immune Evasion, Dissemination, and Persistence in Leishmania amazonensis Infection

Parasite Immunology, Volume 48, Issue 1, January 2026.
ABSTRACT Leishmania amazonensis is one of the etiological agents of cutaneous leishmaniasis in its localised form. Moreover, this parasite can cause more severe disease conditions, such as diffuse and disseminated cutaneous leishmaniasis. The development of more severe clinical manifestations is associated with the parasite's ability to establish a ...

The use of radionuclide DNA probe technology for epidemiological studies of tegumentary leishmaniasis in Mato Grosso state

Brazilian Archives of Biology and Technology, 2005
DNA hybridisation, using probes labelled with 32P, was used to type Leishmania samples isolated from patients living in endemic areas of Mato Grosso State (Brazil), and clinically diagnosed as having tegumentary leishmaniasis.

Health Benefits and Therapeutic Potential of Quercetin

Journal of Food Biochemistry, Volume 2026, Issue 1, 2026.
Quercetin, a polyphenolic compound prevalent in many fruits, vegetables, and other dietary sources, has attracted considerable interest due to its extensive health benefits. This review examines its diverse biological properties, particularly its antioxidant and anti‐inflammatory effects. The study integrates recent scientific findings to elucidate the

Development of Colombian isolates of Leishmania (Viannia) panamensis, Le. (V.) guyanensis and Le. (V.) braziliensis in the sandfly Lutzomyia intermedia (Lutz & Neiva, 1912) under experimental conditions

Memorias do Instituto Oswaldo Cruz, 1993
The development of Colombian Leishmania species of the subgenus Viannia in Lutzomyia intermedia was similar to that observed with Brazilian Le. (V.) braziliensis: colonization of the pylorus by paramastigotes; promastigotes in the midgut and massive ...

Piplartine as an Innovative Natural Product With Dual Antiparasitic and Immunomodulatory Actions

Journal of Immunology Research, Volume 2026, Issue 1, 2026.
Neglected tropical diseases (NTDs) remain a major global health burden, disproportionately affecting low‐ and middle‐income regions and demanding innovative therapeutic strategies. This review summarizes current evidence on piplartine (piperlongumine), a naturally occurring amide from Piper species with broad antiparasitic and immunomodulatory ...

Identification of the HSP70-II gene in Leishmania braziliensis HSP70 locus: genomic organization and UTRs characterization

Parasites & Vectors, 2011
Background The heat stress suffered by Leishmania sp during its digenetic life-cycle is a key trigger for its stage differentiation. In Leishmania subgenera two classes of HSP70 genes differing in their 3' UTR were described.

Oxidative Stress Modulation and Antileishmanial Activity of Salvinia auriculata

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
Ethanolic extract of Salvinia auriculata showed significant antioxidant and antileishmanial activities. Salviniside II, the major metabolite, was isolated, structurally characterized, and evaluated, but exhibited weaker antiparasitic effects when compared to the whole extract.

Comparative genomic analysis of Leishmania (Viannia) peruviana and Leishmania (Viannia) braziliensis [PDF]

BMC Genomics, 2015
Le complexe Leishmania (Viannia) braziliensis est responsable de la plupart des cas de leishmaniose tégumentaire du Nouveau Monde. Ce complexe comprend deux espèces étroitement apparentées mais avec une distribution géographique et des phénotypes de maladie différents, L. (V.) peruviana et L. (V.) braziliensis.
