Two key biological features distinguish Trypanosoma evansi from the T. brucei group: independence from the tsetse fly as obligatory vector, and independence from the need for functional mitochondrial DNA (kinetoplast or kDNA). In an effort to better understand the molecular causes and consequences of these differences, we sequenced the genome of an akinetoplastic T. evansi strain from China and...
OBJECTIVES To evaluate the effects of benznidazole on Chagas' disease cardiac prognosis using an experimental dog model of infection. METHODS A total of 28 dogs were divided into three groups: 10 were infected with Trypanosoma cruzi and treated benznidazole during the chronic phase, 10 were infected but untreated, and 8 were non-infected/healthy. The trypanocidal efficacy was measured by para...
BACKGROUND Cutaneous leishmaniasis is a chronic, infectious disease caused by protozoa of the genus leishmania. The incidence of this disease is high in Brazil, with 19,746 new cases having been detected in 2008. The presence of amastigotes in the cytoplasm of histiocytes constitutes diagnosis of the disease; however, their presence is rarely found in late lesions, making histological diagnosis...
The structure of the kinetoplast DNA of Trypanosoma equiperdum has been studied and compared to the structure of the circular mitochondrial DNA extracted from a dyskinetoplastic strain of T. equiperdum. In T. equiperdum wild type, the kinetoplast DNA constitutes approximately 6% of the total cellular DNA and is composed of approximately 3,000 supercoiled minicircles of 6.4 x 10(5) daltons and a...
BACKGROUND We evaluated kDNA PCR/hybridization and quantitative real-time PCR (qPCR) targeting the gene of DNA polymerase of Leishmania infantum for CVL diagnosis and assessment of parasite load in clinical samples obtained invasively and non-invasively. METHODOLOGY/PRINCIPAL FINDINGS Eighty naturally infected dogs from an endemic urban area in Brazil were used. Animals were divided into two ...
BACKGROUND Leishmania donovani is the etiological agent of visceral leishmaniasis (VL) in the Indian subcontinent. However, it is also known to cause cutaneous leishmaniasis (CL) in Sri Lanka. Sri Lankan L. donovani differs from other L. donovani strains, both at the molecular and biochemical level. To investigate the different species or strain-specific differences of L. donovani in Sri Lanka ...
