Canine Leishmaniasis in Rio de Janeiro, Brazil (2000-2015): Taxonomic Characterisation of Etiological Agents and Geospatial Case Analysis. [PDF]

Zoonoses Public Health
ABSTRACT Introduction Canine Leishmaniasis is a vector‐borne zoonotic disease caused by several species of protozoa of the genus Leishmania. In the state of Rio de Janeiro (RJ), Leishmania braziliensis is the most prevalent species causing tegumentary leishmaniasis (TL) and Leishmania infantum is the main causative agent of visceral leishmaniasis (VL).

The Role of Nitric Oxide and Reactive Oxygen Species in the Killing of Leishmania braziliensis by Monocytes from Patients with Cutaneous Leishmaniasis. [PDF]

PLoS ONE, 2016
Human cutaneous leishmaniasis (CL) caused by Leishmania braziliensis, presents an exaggerated Th1 response that is associated with ulcer development. Macrophages are the primary cells infected by Leishmania parasites and both reactive oxygen species (ROS)

Exposure to Leishmania braziliensis triggers neutrophil activation and apoptosis. [PDF]

PLoS Neglected Tropical Diseases, 2015
BACKGROUND: Neutrophils are the first line of defense against invading pathogens and are rapidly recruited to the sites of Leishmania inoculation. During Leishmania braziliensis infection, depletion of inflammatory cells significantly increases the ...

Observations on the sandfly (Diptera: Psychodidae) fauna of Além Paraíba state of Minas Gerais, Brazil, and the isolation of a parasite of the Leishmania braziliensis complex from Psychodopygus hirsuta hirsuta

Memorias do Instituto Oswaldo Cruz, 1985
Dissection of 765 sandflies captured in Além Paraíba (the type locality of Leishmania braziliensis) resulted in the isolation, from Psychodopygus hirsuta hirsuta, of a parasite of the Le. braziliensis complex.Foram dissecados 765 flebótomos capturados em

Minor temperature shifts do not affect chromosomal ploidy but cause transcriptomic changes in Leishmania braziliensis promastigotes in vitro [PDF]

Memorias do Instituto Oswaldo Cruz, 2020
BACKGROUND The leishmaniases are complex neglected diseases caused by protozoan parasites of the genus Leishmania. Leishmania braziliensis is the main etiological agent of cutaneous leishmaniasis in the New World. In recent studies, genomic changes such

Analysis of the specificity of human antibodies to antigens of Leishmania braziliensis braziliensis [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 1989
The antigenicity of promastigotes of Leishmania braziliensis braziliensis (L. b.braziliensis) treated with 1% sodium desoxycholate in 10 mM Tris-Hcl pH 8.2 was analysed by immunoblot using as probes sera from American cutaneous leishmaniasis (ACL), American visceral leishmaniasis (AVL), schistosomiasis, malaria and Chagas' disease. The ACL sera reacted

Unveiling the Leishmanicidal Mechanism of 4-Nerolidylcatechol Isolated From Piper peltatum Against Leishmania infantum. [PDF]

Chem Biodivers
ABSTRACT The present study assessed the leishmanicidal activity of 4‐nerolidylcatechol (4‐NC) (1) isolated from Piper peltatum leaves against promastigotes and amastigotes of Leishmania amazonensis, L. braziliensis, and L. infantum. The plant was fractionated, leading to the isolation and chemical identification of 4‐NC (1). Biochemical techniques were
