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 ...
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 ...
Enzymatic variability and phylogenetic relatedness among Triatoma infestans, T. platensis, T. delpontei and T. rubrovaria
(Heredity, 1996)
Four congeneric species of triatomine bugs, Triatoma platensis, T. delpontei, T. rubrovaria and T. infestans, were examined by multilocus enzyme electrophoresis. These four species are distributed sympatrically throughout ...
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 ...
Isoenzymes as a tool for the identification of Rhodnius species (Hemiptera: reduviidae: Triatominae)
(Research and Reviews in Parasitology, 1996)
ABSTRACT.
Some species of Rhodnius prove difficult to separate on overt morphological characters. leading to difficulties in determining the current distribution of several of the most epidemiologically significant species. ...
Metric differences between silvatic and domestic Triatoma infestans (Heteroptera: Reduviidae) in Bolivia
(Med Entomol, 1997)
Abstract.
One hundred and fifty-seven specimens of Bolivian Triatoma infestans (Klug 1834), including 44 from the silvatic focus at Cochabamba (Bolivia), were compared using morphometric characters of the head capsule. ...
Cryptic speciation in Lutzomyia (Nyssomyia) Trapidoi (Fairchild & Hertic) (Diptera: Psychodidae) detected by multilocus enzyme electrophoresis
(Am. J. Trop Med. Hyg., 1996)
Abstract
Lutzomyia trapidoi is the major vector of cutaneous leishmaniasis in Ecuador. In the framework of an epidemiologic study, female Lu. trapidoi sand flies were captured on human bait in La Tablada and Paraiso ...
