An isoenzyme study of naturally occurring clones of Trypanosoma cruzi isolated from both sides of the West Andes highland
Brenière, Simone Frédérique; Braquemond, Paul; Solari, Aldo; Agnèse, Jean François; Tibayrenc, Michel (Transantions of The Royal Society of Tropical Medicine and Hygiene, 1991)Abstract. Seventy-two stocks of Tripanosoma cruzi isolated from both sides of the West Andes Highland (Bolivia, Chile and Peru) were analysed by isoenzyme electrophoresis at 12 loci. The data, which were interpreted in ... -
High correlation between Chagas' disease serology and PCR-based detection of Trypanosoma cruzi kinetoplast DNA in Bolivian children living in an endemic area
Wincker, Patrick; Bosseno, Marie-France; Britto, Constança; Yaksic, Nina; Cardoso, María Angélica; Médicis Morel, Carlos; Brenière, Simone Frédérique (FEMS Microbiology Letters, 1994)Abstract. The detection of Trypanosoma cruzi kinetoplast DNA by polymerase chain reaction (PCR) amplification is a potentially powerful tool for the parasitological diagnosis of Chagas’ disease. We have applied this technique ... -
Identification of a major 72 kilodalton surface antigen in twelve isolates of Leishmania braziliensis braziliensis
Legrand, Dominique; Desjeux, Philippe; Le Pont, François; Brenière, Simone Frédérique; Lemesre, Jean-Loup; Santoro, Ferrucio; Capron, André (Molecular and Biochemical Parsitology, 1987)The study of the surface antigens of Leishmania braziliensis braziliensis revealed a great homogeneity among ten strains isolated from Bolivia and two reference strains from Brazil and Belize. A 72 kDa major protein, ... -
Identification of Trypanosoma brucei gambiense group I by a specific kinetoplast DNA probe
Mathieu-Daude, François; Bicart-See, Alain; Bosseno, Marie-France; Brenière, Simone Frédérique; Tibayrenc, Michel (Am J Trop. Med. Hyg., 1994)Abstract. A set of 26 Tripanosoma brucei stocks from various African countries, previously characterized by multilocus enzyme electrophoresis (MLEE) for l8 polymorphic loci, have been selected to be representative of the ... -
Immune response to Trypanosoma cruzi shed acute phase antigen in children from an endemic area for Chagas'disease in Bolivia
Brenière, Simone Frédérique; Yaksic, Nina; Telleria, Jenny; Bosseno, Marie France; Noireau, François; Wincker, Patrick; Sánchez, Daniel (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 ... -
L'analyse SDS-PAGE des protéines et antigènes de surface révèle une forte hétérogénéité chez les clones naturels de Trypanosoma cruzi, corrélée à la variabilité isoenzymatique
Brenière, Simone Frédérique; Araniki, Ivan; Le Ray, Dominique; Tibayrenc, Michel (C.R. Acad. Sci., 1991)Résumé. Les profils des protéines de Surface et des antigènes de surface de 19 clones de laboratoire de Trypasonoma cruzi, représentant 17 profils isoenzymatiques differents (zymodémes), ont été comparés par analyse ... -
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
Brenière, Simone Frédérique; Tibayrenc, Michel; Antezana, Gerardo; Pabón, Javier; Carrasco, Roxana; Selaes, Hugo; Desjeux, Philippe (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 ... -
Résultats préliminaires en faveur de l'existence d'un antigène majeur de surface, spècifique de Leishmania braziliensis braziliensis
Legrand, Dominique; Desjeux, Philippe; Prina, Eric; Le Pont, François; Brenière, Simone Frédérique (C.R. Acad. Sc., 1986)L'étude comparative des antigénes de surface de l0 souches boliviennes clonées et d'une souche brésilienne de référence de la sous-espèce L. b. braziliensis a permis de mettre en évidence une grande homogénéité au sein de ... -
Specific humoral depression in chronic patients infected by Trypanosoma cruzi
Brenière, Simone Frédérique; Poch, Olivier; Selaes, Hugo; Tibayrenc, Michel; Lemesre, Jean-Loup; Antezana, Gerardo; Desjeux, Philippe (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 ... -
Transmission transplacentaire des anticorps anti-Trypanosoma cruzi
Brenière, Simone Frédérique; Bailly, Martine; Carrasco, Roxana; Carlier, Yves (Cah. O.R.S.T.O.M., 1983)Résumé. La transmission transplacentaire des anticorps anti-Trypanosoma crtzi a été étudiée chez 38 mères chagasiques. Les taux des anticorps anti-T. cruzi sont semblables dans le sérum de la mère et celuid du cordon. ... -
Trypanosoma cruzi : study of the distribution of two widespread clonal genetypes in Bolivian Triatoma infestans vectors shows a high frequency of mixed infestions
Bosseno, Marie-France; Telleria, Jenny; Vargas, Fernando; Yaksic, Nina; Noireau, François; Morin, Annie; Brenière, Simone Frédérique (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 ...
