Karyotype and spermatogenesis in Triatoma lenti (Hemiptera: Triatominae), a potential Chagas vector
(Genetics and Molecular Research, 2012-01-01) [Artigo]
All species of Triatominae are susceptible to infection by Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae) and consequently, potential insect vectors of Chagas disease. Currently, there are 140 known species of ...
ABO blood groups and Helicobacter pylori cagA infection: evidence of an association
(Journal of Venomous Animals and Toxins Including Tropical Diseases, 2010-01-01) [Artigo]
Diseases resulting from Helicobacter pylori infection appear to be dependent on a host of genetic traits and virulence factors possessed by this microorganism. This paper aimed to investigate the association between the ...
Cytogenetic and morphologic approaches of hybrids from experimental crosses between Triatoma lenti Sherlock & Serafim, 1967 and T. sherlocki Papa et al., 2002 (Hemiptera: Reduviidae)
(Infection Genetics And Evolution, 2014-08-01) [Artigo]
The reproductive capacity between Triatoma lenti and Triatoma sherlocki was observed in order to verify the fertility and viability of the offspring. Cytogenetic, morphological and morphometric approaches were used to ...
Spermatogenesis in Triatoma melanocephala (Hemiptera: Triatominae)
(Genetics and Molecular Research, 2013-01-01) [Artigo]
Triatoma melanocephala is a rare species of Hemiptera. It belonged to the Brasiliensis subcomplex and presents morphological characteristics very close to those of Triatoma vitticeps. We investigated spermatogenesis of T. ...
Origin and distribution of AT-rich repetitive DNA families in Triatoma infestans (Heteroptera)
(Infection, Genetics and Evolution, 2014-04-01) [Artigo]
Triatoma infestans, one of the most important vectors of Trypanosoma cruzi, is very interesting model, because it shows large interpopulation variation in the amount and distribution of heterochromatin. This polymorphism ...
Heteropyknotic filament in spermatids of Triatoma melanocephala and T. vitticeps (Hemiptera, Triatominae)
(Invertebrate Reproduction & Development, 2014-01-01) [Artigo]
The species Triatoma melanocephala and T. vitticeps are vectors of Chagas disease in Brazil. An analysis of the number of chromosomes has led to the proposal of the exclusion of both these species and T. tibiamaculata from ...
