Specific humoral depression in chronic patients infected by Trypanosoma cruzi
(Rev. Inst. Méd. Trop., 1984)
SUMMARY.
We performed a comparative study between xenodiagnosis and serological
tests for Chagas’disease. 150 Patients from several endemic areas were studied.
Four of them appeared to have a peculiar status with positive ...
Genetic variability and microdistribution of Triatoma infestans genotypes and Trypanosoma cruzi clones in Arequipa región (Peru)
(Mem. Inst. Oswaldo Cruz, 1997)
The genetic variability of Triatoma infestans and Trypanosoma cruzi populations was studied by isoenzyme analysis in two distinct areas of Arequipa province (Peru); one, Santa Rita de Siguas, being an endemic area for ...
Immune response to Trypanosoma cruzi shed acute phase antigen in children from an endemic area for Chagas'disease in Bolivia
(Mem. Inst. Oswaldo Cruz, 1997)
A field study of the immune response to the shed acute phase antigen (SAPA) of Trypanosoma cruzi was carried out in the locality of Mizque, Cochabamba department, Bolivia. Schoolchildren (266), with an average of 8.6 ± 3.6 ...
Enzymatic variability and phylogenetic relatedness among Triatoma infestans, T. platensis, T. delpontei and T. rubrovaria
(Heredity, 1996)
Four congeneric species of triatomine bugs, Triatoma platensis, T. delpontei, T. rubrovaria and T. infestans, were examined by multilocus enzyme electrophoresis. These four species are distributed sympatrically throughout ...
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 ...
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 ...
The origin of Rhodnius prolixus in Central America
(Medical and Veterinary Entomology, 1998)
Rhodnius prolixus Stal (Hemiptera, Reduviidae) is the main domestic vector of Chagas disease in Venezuela and Colombia, and also in parts of Central América (El Salvador, Guatemala, Honduras and Nicaragua). In Central ...
Inter-relation of sylvatic and domestic transmission of Trypanosoma cruzi in areas with and without domestic vectorial transmission in Minas Gerais, Brazil
(Mem. Inst. Oswaldo Cruz, 1995)
During the period 1980-1986, we captured triatomine bugs and mammalian reservoir hosts from sylvatic and domestic situations in different municipalities of the State of Minas Gerais. Trypanosoma cruzi was isolated from ...
