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 ...

Leishmania (Viannia) braziliensis Inositol Phosphorylceramide: Distinctive Sphingoid Base Composition [PDF]

Frontiers in Microbiology, 2017
Inositol phosphorylceramide (IPC), the major sphingolipid in the genus Leishmania but not found in mammals, is considered a potentially useful target for chemotherapy against leishmaniasis.

Clonal variation within a mucosal isolate derived from a patient with Leishmania (Viannia) braziliensis infection Variação clonal de um isolado derivado de um paciente com infecção mucosa pela Leishmania (Viannia) braziliensis [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 1991
Three isolates over 5 years from a patient with persistent relapsing mucosal leishmaniasis due to Leishmania (Viannia) braziliensis and 7 clones from one of these isolates were studied by zymodemes and scrodemes analysis.

Effective Genome Editing in Leishmania (Viannia) braziliensis Stably Expressing Cas9 and T7 RNA Polymerase [PDF]

Frontiers in Cellular and Infection Microbiology, 2021
Until 2015, loss-of-function studies to elucidate protein function in Leishmania relied on gene disruption through homologous recombination. Then, the CRISPR/Cas9 revolution reached these protozoan parasites allowing efficient genome editing with one ...

Leishmania (Viannia) braziliensis type 2 as probable etiological agent of canine cutaneous leishmaniasis in Brazilian Amazon. [PDF]

PLoS ONE, 2019
Canine cutaneous leishmaniasis (CCL) is a zoonosis of public health interest, and in the Americas, Leishmania (Viannia) braziliensis has been identified as the main etiological agent. The present study sought to investigate Leishmania spp.

Leishmania (Viannia) braziliensis growth in vitro culture relies more on folic acid availability than Leihsmania (Leishmania) amazonensis [PDF]

Memorias do Instituto Oswaldo Cruz, 2005
We compared the in vitro growth of promastigotes from two Leishmania species in TC-100 and Schneider media. Leishmania (Leishmania) amazonensis replication rates were similar in both tissue culture media and reached maximum rates by 48 h.

An integrated molecular approach for the detection and species-level identification of Leishmania spp. in clinical samples [PDF]

Microbiology Spectrum
Leishmaniases are parasitic diseases transmitted by infected sand flies, present in over 98 countries. Accurate diagnostic tools are critical for prevention and control, especially in non-endemic areas.

Mixed infection with Leishmania (Viannia) braziliensis and Leishmania (Leishmania) chagasi in a naturally infected dog from Rio de Janeiro, Brazil

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2006
We report here the first case of co-infection with Leishmania (Viannia) braziliensis and Leishmania (Leishmania) chagasi in a naturally infected dog from Rio de Janeiro, Brazil. Isoenzyme characterisation identified the parasites isolated in culture from
