A genetic comparison between Brazilian and Bolivian zymodemes of Trypanosoma cruzi
(Transactions of The Royal Society of Tropical Medicine and Hygiene, 1983)
Abstract.
The enzyme profiles of three major Brazilian Trypanosoma cruzi zymodemes (Brazilian Z1, Brazilian Z2, Brazilian Z3) and of two principal Bolivian zymodemes were compared. Relationships were assessed both ...
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 ...
General classification of the isoenzymic strains of Trypanosoma (Schizotrypanum) cruzi and comparison with T. (S.) C. Marinkellei and T. (Herpetosoma) rangeli
(Ann. Soc. Belge Med. Trop., 1984)
Summary.
Thirteen laboratory reference stocks of Trypanosoma (Schizottypanum) cruzi were classified according to genetic distance by enzyme analysis of 14 loci. Three principal isoenzymic strains were recognized together ...
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 ...
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 ...
New electrophoretic evidence of genetic variation and diploidy in Trypanosoma cruzi, the causative agent of Chagas' disease
(Genética, 1985)
Abstract.
By changing clcctrophoretic conditions additional genetic variability was observed in both previously and newly analysed enzymatic systemes in Trypanosoma cruzi . Inferences the quaternary structure of enzymes ...
Isozymic studies and epidemiological data of Trypanosoma cruzi from Arequipa (Perú), Pacific side
(Ann. Soc. Belge Med. Trop., 1985)
Summary.
The authors present some epidemiological data (infestation rates for houses and triatomine vectors) concerning Chagas' disease in Arequipa region (Peru).
lsoenzymic analysis of 39 Trypanosoma cruzi stocks from ...
Isozymic variability of Trypanosoma cruzi : biological and epidemiological significance
(Ann. Soc. Belge Med. Trop., 1985)
Summary.
Genetic interpretation of. T. cruzi zymograms has led to various hypotheses which are reviewed.
Addional data on Trypanosoma cruzi isozymic strains encountered in Bolivian domestic transmission cycles
(Transantions of The Royal Society of Tropical Medicine and Hygiene, 1986)
Abstract.
We have collected in Bolivia 212 stocks of Trypanosoma cruzi from domestic transmission cycles and have assayed for nine enzyme systems (11 gene loci). Only a few different isozyme profiles exist,
without ...
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 ...
