Recovery of Leishmania (Viannia) braziliensis from Inoculated Hamsters
The Journal of Parasitology, 1988Leishmania (Viannia) braziliensis has never been isolated from wild animals although it is apparently capable of inducing infections in man, dogs, and donkeys. An analysis of the standard hamster culture system for analyzing infectivity of Leishmania sp. was undertaken. Results indicate that for L.

Immunological selection forLeishmania(Viannia)braziliensisantigens
Annals of Tropical Medicine & Parasitology, 2001Comparative ELISA and selective immunoblotting procedures were used in attempts to identify differential serological indicators of infection with the Leishmania (Viannia) braziliensis complex, infection with the L. braziliensis species, and therapeutic cure of localized or mucocutaneous leishmaniasis (LCL or MCL).

American tegumentary leishmaniasis (ATL) in Peru is mainly associated with Leishmania (Viannia) peruviana and L. (V.) braziliensis. These parasites are genetically related, and their characterization as distinct species is controversial. Despite their genetic similarity, each species is associated with different clinical manifestations of ATL; L.

The antibody response against Leishmania (Leishmania) amazonensis crude antigen was measured through the indirect immunofluorescent assay (IFA) and the immunoenzymatic assay (ELISA) in 114 patients with cutaneous leishmaniasis (CL) in Brazil. Fifty-four patients were infected by Leishmania (Viannia) braziliensis, and 60 patients had L.

Clinical complexity of Leishmania (Viannia) braziliensis infections amongst travelers
European Journal of Dermatology, 2013The protozoan parasite Leishmania (Viannia) braziliensis is one of the main causes of cutaneous and mucocutaneous leishmaniasis in South America. Here, we describe three cases of L. (V.) braziliensis infection which were acquired during travelling in Bolivia, Peru or Paraguay and illustrate the phenotypic heterogeneity and therapeutic complexity of the

Leishmania (Viannia) braziliensis identification by PCR in the state of Para, Brazil
Transactions of the Royal Society of Tropical Medicine and Hygiene, 2011The incidence of cutaneous leishmaniasis (CL) is increasing and there is limited surveillance of Leishmania species throughout the world. We identified the species associated with CL in a region of Amazonia, an area recognized for its Leishmania species variability.

In vitro selection of ketoconazole-pentamidine-resistant Leishmania (Viannia) braziliensis strains
Experimental Parasitology, 2022The use of ketoconazole (KTZ) plus pentamidine (PMD) could be an interesting treatment option for New World cutaneous leishmaniasis. The aim of this work was to generate KTZ- and PMD-resistant strains and to determine some characteristics of the selection process and the resulting parasites.

Heparin binding proteins from Leishmania (Viannia) braziliensis promastigotes
Veterinary Parasitology, 2007We have examined the heparin binding proteins from Leishmania (Viannia) braziliensis promastigotes (HBP-Lb) by chromatography assays. The proposed strategy to isolate an enriched fraction of the HBP-Lb consisted of an association of the Triton X-114 method with affinity chromatography in heparin-Sepharose 4B column.

Azithromycin, an azalide antibiotic, is highly concentrated within different phagocytic cells, especially macrophages. The potential antileishmanial activity of azithromycin against three species of Leishmania from the New World was assessed using in vitro models.

Galleria mellonella hemocytes: A novel phagocytic assay for Leishmania (Viannia) braziliensis
Journal of Microbiological Methods, 2016Galleria mellonella is an excellent invertebrate model for the study of diseases that involve interactions with cells from the innate immune system, since they have an innate immune system capable of recognizing the pathogens. Here we present for the first time, an alternative model for an in vitro phagocytic assay using hemocytes of G.
