Persistent Infections by Leishmania (Viannia) braziliensis [PDF]

Memorias do Instituto Oswaldo Cruz, 1997
Here we review the phenomenon of persistency in Leishmania (Viannia) braziliensis infections. In other Leishmania species where appropriate animal models exist, considerable advances in the understanding of basic immunologic mechanisms of persistency ...

Protection and Pathology in Leishmania braziliensis Infection. [PDF]

Pathogens, 2022
Leishmania killing is mediated by IFN-γ-activated macrophages, but IFN-γ production and macrophage activation are insufficient to control L. braziliensis infection. In American tegumentary leishmaniasis (ATL), pathology results from an exaggerated inflammatory response.

Histone post-translational modifications of Leishmania braziliensis. [PDF]

Sci Data
Histone post-translational modifications (hPTMs) constitute an epigenetic mechanism that plays a fundamental role in the regulation of gene expression in eukaryotic cells. In trypanosomatid parasites, such as Trypanosoma brucei, T. cruzi and Leishmania spp., gene regulation occurs mainly at the post-transcriptional level.

Experimental canine mucocutaneous leishmaniasis (Leishmania braziliensis braziliensis) [PDF]

Memórias do Instituto Oswaldo Cruz, 1988
Four mongrel dogs were intradermically inoculated with 3 x 10**6 Leishmania braziliensis braziliensis promastigotes. Three out of the four animals developed cutaneous lesions respectively 4, 7, and 8 months after. The fourth dog did not develop lesion at the inoculation site, but a mucosal ulcer was seen 16 months after the inoculum.

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
