Prevalencia de la infección por Trypanosoma Cruzi en bancos de sangre de siete departamentos de Bolivia
(Papiro, 1990)Abstract Trypanosoma cruzi infection was studied in 1,298 sera samples of blood banks from 7 capital departments of Bolivia, using the immunofluorescence test (IFI) and Enzyme Linked Immunosorbent Assay (ELISA). The ... -
Présence en Bolivie de sept nouveaux variants isoenzymatiques de Trypanosoma cruzi. Considérations taxonomiques et épidémiologiques. Discussion sur la valeur antigénique potentielle de certaines isoenzymes
(Cah. O.R.S.T.O.M., 1983)Abastract. Les auteurs décrivent la variabilité génétique de 45 isolats boliviens de Trypanosoma cruzi à l’aide de 12 loci isoenzymatiques. Ils montrent la présence de deux groupes principaux, avec cependant une importante ... -
Résultats préliminaires en faveur d'une relation faible ou inexistante entre les formes cliniques de la maladie de Chagas et les souches isoenzymatiques de Trypanosoma cruzi
(C.R. Acad. Sc., 1985)MEDICINE AND THERAPEUTICS. Preliminary results in favour of a weak or non-existent relationship between the clinical forms of Chagas'disease and Trypanosoma cruzi isozymic strains. Trypanosoma cruzi stains obtained by ... -

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 ... -
Sur le statut taxonomique et médical des souches isoenzymatiques de Trypanosoma cruzi. Considérations sur la valeur systématique et immunogénique des différentes isoenzymes
(C.R. Acad. Sc., 1983)Resumme. Les calculs de distances génétique pour 45 isolats boliviens de Trypanosoma cruzi montrent l’absence de continuum parmi eux et permettent de distinguer deux groupes principaux, dont l’origine est peut-être une ... -
Sylvatic triatomines (Hemiptera: Reduviidae) in Bolivia : trends toward domesticity and possibleinfection with Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae)
(Journal of Medical Entomology, 1995)ABSTRACT The risk of domestic transmission of Trypanosoma cruzi (Chagas) by sylvatic triatomines was assessed in an isolated area of the subandean region of Bolivia. None of the 390 residents examined had serological ... -
The 70-kDa heat-shock protein is a major antigenic determinant in human Trypanosoma cruzi/Leishmania braziliensis braziliensis mixed infection
(Immunology Letters, 1991)Summary. Five sera from Bolivian individuals chronically infected by Trypanosoma cruzi, and suffering an active Leishmania braziliensis braziliensis metastasic mucocutaneous lesion were characterized. They reacted with ... -
The interest of immunoprecipitation tests in the immunological diagnosis of Chagas'disease
(Ann. Soc. Belge Med. Trop., 1985)Summary. lmmunoelectrophoresis (lEP) and a double diffusion microtest (MD) were evaluated for ¡mmunological diagnosis of Chagas' d¡sease, using 527 sera from Bolivian patients. The specificity of, the tests was given ... -
The microdistribution of isoenzymic strains of Trypanosoma cruzi in southern Bolivia; new isoenzyme profiles and further arguments against Mendelian sexuality
(Transactions of The Royal Society of Tropical Medicine and Hygiene, 1984)Abstract. 132 Trypanosoma cruzi stocks were collected in southern Bolivia (99 stocks in Tupiza, 33 in Tarija), and were characterized using five enzymes (six loci). From these 132 stocks, a sample of 21 was studied using ... -
The presence in Bolivia of two distinct zymodemes of Trypanosoma cruzi, circulating sympatrically in a domestic transmission cycle
(Transactions of The Royal Society of Tropical Medicine and Hygiene, 1983)Abstract. The enzyme profiles of 109 Bolivian stocks of Trypanosoma cruzi were determined by cellulose acetate electrophoresis using the four enzymes: malate dehydrogenase (oxaloacetate decarboxylating) (NADP+) (E.C.1.1.1.40, ... -
Trypanosoma cruzi : a pharmacological comparison of some Bolivian isoenzymic strains
(Ann. Soc. Belge Med. Trop., 1983)Summary . The drug susceptibility of 3 isoenzymic strains of Trypanosoma cruzi was studied. Two drugs (SQ 18, 506 and Ro 7-1051) and 6 stocks were used. The drug test was carried out on epimastigote cultures. Significant ... -
Trypanosoma cruzi : expression of antigenic component 5 among 35 laboratory clones obtained from 18 different isozymic variants
(Rev. Inst. Méd. Trop., 1987)Summary. Two monoclonal antibodies anti-component 5 of Trypanosoma cruzi (I-35/115 and II-190/30) were tested in IFA and ELISA respectively against 35 T. cruzi laboratory clones. Among the 35 clones tested, 18 different ... -
Trypanosoma cruzi : measurement of DNA quantity in different isoenzymic strains. Inferences on the ploidy of these strains
(Ann. Soc. Belge Med. Trop., 1983)Summary. The DNA quantity in different isoenzymic strains of Trypanosoma cruzi appears to be the same among these strains. This seems to indicate that these strains have the same ploidy. Genetic distances may be used for ... -
Trypanosoma cruzi : study of the distribution of two widespread clonal genetypes in Bolivian Triatoma infestans vectors shows a high frequency of mixed infestions
(Experimental Parasitology, 1996)Abstract. The detection of two widespread Trypanosoma cruzi clonal genotypes (20 and 39) in feces of Bolivian specimens of the vector Triatoma infestans was performed by a combination of polymerase chain reaction and ... -
Trypanosoma cruzi populations : more clonal than sexual
(Parasitology Today, 1987-06)The ancient guestion of trypanosome sexuality has recently been reactivated in view of important observations in the African species Trypanosoma brucie, in which Mendelian sexuality has been proposed as o working hypothesis ... -
