Copy number differences in the 195 BP repeated satellite DNA from Trypanosoma cruzi and Trypanosoma rangeli : potential use for epidemiologic surveys
(Mem. Inst. Oswaldo Cruz, 1993)
Trypanosoma cruzi, the agent of Chagas' disease, and the apparently non-pathogenic species Trypanosoma rangeli can be both encountered in human and in the same mammiferous hosts. On fresh isolates, the discrimination between ...
Population genetics of Trypanosoma cruzi and Trypanosoma rangeli : taxonomical and epidemiological purpose
(Biol Res, 1993)
A genetic analysis of a set of Trypanosoma cruzi and Trypanosoma rangeli stocks was performed by two combined approaches, namely mutilocus enzyme electrophoresis (MLEE) and labeling by DNA probes. A considerable genetic ...
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 ...
Direct identification of Trypanosoma cruzi natural clones in vectors and mammalian hosts by polymerase chain reaction amplification
(Am. J. Trop. Med. Hyg., 1992)
Abstract. The polymerase chain reaction was used to amplify the highly variable region
of the kinetoplast minicircle of Trypanosoma cruzi directly in biological samples (feces of
infected Triatomine bugs, blood samples ...
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 ...
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 ...
