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 ...

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.

Extreme inbreeding in Leishmania braziliensis [PDF]

Proceedings of the National Academy of Sciences, 2009
Leishmania species of the subgenus Viannia and especially Leishmania braziliensis are responsible for a large proportion of New World leishmaniasis cases. The reproductive mode of Leishmania species has often been assumed to be predominantly clonal, but ...

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.

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

Comparative expression profiling of Leishmania: modulation in gene expression between species and in different host genetic backgrounds. [PDF]

, 2009
Genome sequencing of Leishmania species that give rise to a range of disease phenotypes in the host has revealed highly conserved gene content and synteny across the genus.
