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 ...
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 ...
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. ...
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 ...
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. ...
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 ...
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 ...
