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 ...
An isoenzyme study of naturally occurring clones of Trypanosoma cruzi isolated from both sides of the West Andes highland
(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 ...
Antigenic specificity of the 72-kilodalton major surface glycoprotein of Leishmania braziliensis braziliensis
(Journal of Clinical Microbiology, 1991)
We examined the expression and the antigenicity of the major surface polypeptides of Leishmania braziliensis braziliensis and Leishmania donovani chagasi, parasites which commonly coexist in the same endemic areas of ...
Isolement et synthese de l'espintanol, nouveau monoterpene antiparasitaire
(Journal of Natural Products, 1991)
Abstract. The in vitro leishmanicidal and trypanocidal activities of a petroleum ether
extract of Oxandra espintana have been investigated. Four aromatic monoterpenes were isolated, of which two are novel: espintanol ...
Matrix remodelling and fibroblast phenotype in early lesions of human cutaneous Leishmaniasis
(Path. Res. Pract., 1991)
SUMMARY.
The connective matrix participates directly in early pathological events observed in the
cutaneous lesion of leishmaniasis, due to Leishmania braziliensis guyanensis. A sample of
19 skin biopsies was examined ...
Propositon of a standard description for phlebotomine sandflies
(Parassitologia, 1991)
Abstract. In order to be comparable, and efficient, the descriptions need to be as complete as possible and realized according to the same parameters. In this respect, we present the standard description of Phlebotomine ...
Morphometrie alaire et caracterisation specifique des phlebotomes
(Parasitología, 1991)
Abstract.
We study the information included in sandfly wings in order to test this organ as a source for the specific discrimination. The cartesian coordinates of the vein intersections are collected using a microscope ...
Binding of the specific ligand to Fc receptors on Trypasonoma cruzi increases the infective capacity of the parasite
(Immunology, 1991)
Summary.
The infective capacity of Trypanosoma cruzi was significantly increased after treatment with monoclonal IgG1 antibodies, whether or not specific for the parasite; minimal or no change in infectivity was seen after ...
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
(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 ...
Évaluation du coût socio-économique de la leishmaniose cutanée en Guyane française
(Rev. Epidém. et Santé Publ., 1991)
Le coût socio-économique de la leishmaniose en Guyane française a été évalué par une
enquête rétrospective ayant porté sur une période d'une année: 1979-80. Les éléments de
coût chiffrables pris en compte ont été les ...
