Dissemination of Leishmania (Viannia) braziliensis
Journal of Comparative Pathology, 1996Destructive human mucocutaneous leishmaniasis may appear many years after the primary cutaneous infection with Leishmania (Viannia) braziliensis. Hamsters (Mesocricetus auratus) were infected with metacyclic L. braziliensis promastigotes. It was found that secondary metastatic visceral lesions could arise from a primary cutaneous lesion, or secondary ...

Concurrent human infection withLeishmania donovaniandLeishmania braziliensis braziliensis
Annals of Tropical Medicine & Parasitology, 1986In the suburban district of Campo Grande, Municipality of Rio de Janeiro (Brazil) cases of both Leishmania domovani and L. b. braziliensis infections occur. In March 1982 we examined a white male child, five years old, with fever, weight loss and distended abdomen, symptoms said to have started three months before.

Purine metabolism in Leishmania donovani and Leishmania braziliensis
Biochimica et Biophysica Acta (BBA) - General Subjects, 1978We have studied purine metabolism in the culture forms of Leishmania donovani and Leishmania braziliensis. These organisms are incapable of synthesizing purines de novo from glycine, serine, or formate and require an exogenous purine for growth. This requirement is better satisfied by adenosine or hypoxanthine than by guanosine.

Clinical presentations of Leishmania braziliensis braziliensis
Parasitology Today, 1985Leishmania braziliensis braziliensis (Lbb) is probably the most serious, leishmanial infection of the New World. Although epidemiological information is incomplete, its distribution is believed to extend from Belize in Central America to northern Argentina, involving all countries east of the Andes.

Identification of Serine Proteases from Leishmania braziliensis
Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 2007 Leishmania (V.) braziliensis is one of the most important ethiologic agents of the two distinct forms of American tegumentary leishmaniasis (cutaneous and mucosal). The drugs of choice used in leishmaniasis therapy are significantly toxic, expensive and are associated with frequent refractory infections.

Production and secretion of Leishmania braziliensis proteins
Molecular and Biochemical Parasitology, 1980The kinetics of secretion of proteins by Leishmania braziliensis was followed by incorporation of [3H]leucine into macromolecules produced by the cells which are released into the growth medium. About 10% of the total protein synthesized by actively growing cells is secreted.

Leishmania braziliensis: Localization of glycoproteins in promastigotes
Experimental Parasitology, 1986Two species of glycoproteins from Leishmania braziliensis promastigotes of apparent molecular weights of 53,000 (glycoprotein 53) and 47,000 (glycoprotein 47) were localized. Four lectins with different sugar specificities bound to the blotting sheet to which the electrophoretically separated materials were transferred.

The Tree-Buttress Biotope: a Pathobiocenose of Leishmania Braziliensis
The American Journal of Tropical Medicine and Hygiene, 1982A total of 52,033 sandflies, comprising 33 species, was collected in tree buttresses in Panama. Of the 18,025 females collected, 1,592 (8.8%) engorged phlebotomines of 18 species contained sufficient blood for identification of their vertebrate hosts by the microcapillary precipitin method. Lutzomyia ylephiletor and Lu.
