Lutzomyia whitmani(Diptera: Psychodidae) as vector ofLeishmania (V.) braziliensisin Paraná state, southern Brazil

Annals of Tropical Medicine & Parasitology, 2000
The phlebotomine sandflies in the northern areas of the state of Paraná, Brazil, particularly those in the '16a' health region, were investigated over a 3-year period. Using CDC light traps (with and without hamster bait) and Shannon traps (with lights and horse or human bait), 16 species were collected from seven municipal districts which were known ...

Leishmania ( V .) braziliensis infecting bats from Pantanal wetland, Brazil: First records for Platyrrhinus lineatus and Artibeus planirostris

Acta Tropica, 2017
(Uploaded by Plazi for the Bat Literature Project) In the New World genus Leishmania parasites are etiological agents of neglected zoonoses known as leishmaniasis. Its epidemiology is very complex due to the participation of several species of sand fly vectors and mammalian hosts, and man is an accidental host.

AIM2 inflammasome is associated with disease severity in tegumentary leishmaniasis caused by Leishmania (V.) braziliensis

Parasite Immunology, 2017
SummaryThe inflammasome is a multiprotein signalling platform involved in the pathogenesis of various inflammatory skin diseases. Herein, we investigated gene and protein expression of the inflammasome molecules AIM2 and NLRP3 in active lesions from patients with L.

Antileishmanial activity evaluation of a natural amide and its synthetic analogs against Leishmania (V.) braziliensis: an integrated approach in vitro and in silico

Parasitology Research, 2021
Leishmaniasis is considered a neglected disease, which makes it an unattractive market for the pharmaceutical industry; hence, efforts in the search for biologically active substances are hampered by this lack of financial motivation. Thus, in the present study, we report the leishmanicidal activity and the possible mechanisms of action of compounds ...

Immunopathogenic competences ofLeishmania(V.)braziliensisandL.(L.)amazonensisin American cutaneous leishmaniasis

Parasite Immunology, 2009
SummaryThe immunopathogenic competences ofLeishmania (V.) braziliensisandL. (L.) amazonensiswere reviewed in the light of more recent features found in the clinical and immunopathological spectrum of American cutaneous leishmaniasis. It was shown a dichotomy in the interaction between theseLeishmaniaspecies and human T‐cell immune response; whileL. (V.)

Leishmania in phlebotomid sandflies V. The nature and significance of infections of the pylorus and ileum of the sandfly by leishmaniae of the braziliensis complex

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1977
A study of two isolates of Leishmania braziliensis braziliensis in the hindgut of experimentally infected Lutzomyia longipalpis was made with the light and electron microscopes. Infections were always heavier in the pylorus than the ileum, and no parasites were found in the rectum.

Intralesional therapy of American cutaneous leishmaniasis with pentavalent antimony in Rio de Janeiro, Brazil – an area of Leishmania (V.) braziliensis transmission

International Journal of Dermatology, 1997
Abstract Background The drug of choice for leishmaniasis is pentavalent antimony and different regimens are under continuous evaluation. The ideal therapy should be simple, effective, and with no or minor side‐effects, in this paper we have studied the efficacy of intralesionally applied antimony in New World cutaneous leishmaniasis.

Comparison of cutaneous leishmaniasis due to Leishmania (Viannia) braziliensis and L. (V.) guyanensis in Brazil: therapeutic response to meglumine antimoniate.

The American journal of tropical medicine and hygiene, 2001
We conducted a quasi-experimental study to compare the response to meglumine antimoniate in patients with localized cutaneous leishmaniasis from two endemic areas of Brazil that were infected by two Leishmania species. Sixty-one were infected by Leishmania (Viannia) braziliensis (group B) and 57 by L. (V.) guyanensis (group G).

Leishmania (V.) braziliensis and L. (L.) amazonensis promote differential expression of dendritic cells and cellular immune response in murine model

Parasite Immunology, 2012
SummaryThe expression of Langerhans cell (LC) and dermal dendritic cell (dDC) as well as T CD4+ and CD8+ immune responses was evaluated in the skin of BALB/c mice experimentally infected by L. (L.) amazonensis (La) and L. (V.) braziliensis (Lb). At 4th and 8th weeks post infection (PI), skin biopsies were collected to determine the parasite load and ...
