Direct identification of Trypanosoma cruzi natural clones in vectors and mammalian hosts by polymerase chain reaction amplification
(Am. J. Trop. Med. Hyg., 1992)
Abstract. The polymerase chain reaction was used to amplify the highly variable region
of the kinetoplast minicircle of Trypanosoma cruzi directly in biological samples (feces of
infected Triatomine bugs, blood samples ...
Biological and chemical studies of Pera benensis, a Bolivian plant used in folk medicine as a treatment of cutaneous leishmaniasis
(Journal of Ethnopharmacology, 1992)
The stem barks of Pera benensis are employed by the Chimane Indians in the Bolivian Amazonia as treatment of cutaneous leishmaniasis caused by the protozoan Leishmania braziliensis. The chloroform extracts containing ...
Circulation and behaviour of two major clones of Trypanosoma cruzi in Bolivian cycles
(Mem. Inst. Oswaldo Cruz, 1996-11)
On the basis of isoenzyme studies and population genetic interpretation (Tibayrenc et al. Proc. Nat. Acad. Sci. USA, 83 : 115-119, 1986), we have previously designed a molecular identification tool of two major clones of ...
PCR-based diagnosis for Chagas' disease in Bolivian children living in an active transmission area : comparison with conventional serological and parasitological diagnosis
(Parasitology, 1997)
Abstract.
A large field study has been performed in the Cochabamba region of Bolivia with the aim of comparing the polymerase chain reaction (PCR) with other diagnostic methods for Chagas' disease. The amplification of ...
Field application of polymerase chain reaction diagnosis and strain typing of Trypanosoma cruzi in Bolivian triatomines
(Am. J. Trop. Med. Hyg., 1995)
Abstract.
A new approach for direct identification and characterization of Trypanosoma cruzi stocks in biological samples was tested for field applicability on an extensive sample of feces collected from triatomine vectors ...
Serodiagnóstico de la Trypanosomiasis americana en una población infantil : análisis epidemiológico
(BIOFARBO, 1997)
La enfermedad de Chagas, ha sido reconocida como un problema mayor de Salud Pública estos últimos años. En Bolivia, la población infantil presenta un alto riesgo de infección por Trypanosoma cruzi en zonas endémicas. En ...
In vitro activity and mutagenicity of bisbenzylisoquinolines and quinones against Trypanosoma cruzi Tripomastigotes
(PHYTOTHERAPY RESEARCH, 1994)
Abstract. The accidental transmission of Chagas' disease by donor blood is recognized as a serious problem in the Latin America. This paper describes the screening of natural products as possible new chemoprophylactic ...
Estudio de la interacción entre hibridos de macrófagos humanos y Trypanosoma cruzi
(RADMENT, 1994)
Resumen. Trypanosoma cruzi causa inmunosupresión durante la infección mediante mecanismos que no están totalmente esclarecidos. Dado que fagocitos mononucleares son las principales células en la Trypanosomiasis, nosotros ...
Evaluación de la respuesta humoral de pacientes con lesiones diversas asociadas a la enfermedad de Chagas frente a diferentes antígenos de T. cruzi
(Cuadernos, 1995)
RESUMEN.
Con el fin de encontrar mejores antígenos de T. cruzi, y posibles marcadores inmunológicos, para el diagnóstico de las diferentes formas clínicas del mal de Chagas, se probaron amastigotes y la fracción ...
Population structure of Andean Triatoma infestans : allozyme frequencies and their epidemiological relevance
(Medical and Veterinary Entomology, 1998)
Abstract. Triatoma infestans (Hemiptera: Reduviidae) from 22 Andean localities in Bolivia (n = 968) and Peru (n=37) were analysed by multi-locus enzyme electrophoresis. Among 12 gene-enzyme systems analysed, GPD, 6GPD and ...
