“…Triatoma rubida eggs had ornamentation similar to those in T. tibiamaculata (Obara et al 2007b) with variability in polygon type and surface texture. The major difference between the species was the opercular border, which was thick in T. tibiamaculata eggs compared with those of T. rubida .…”

“…Obara et al (2007b) studied six species in the genus Triatoma and concluded that morphological characteristics of eggs compose a new parameter that may aid in creating future dichotomous keys and support the determination of a role for each vector species. For the species studied, the surface of the exochorion or egg bodies has a polygonal cell‐based ornamentation.…”

We describe and compare the morphology and morphometry of the egg exochorion for five species and two morphotypes of Mexican triatomines with scanning electron microscopy. The results show differences in egg ornamentation for each species, including between morphotypes. Polygonal ornamentation was observed in each species, including pentagons, octagons and, in certain cases, a majority of hexagons. We observed small perforations in T. protracta protracta, small spheres on the T. lecticularia polygons, a crown with festoons in T. barberi, and less complex ornamentation in T. mexicana. Through morphometric analysis, significant differences in egg dimensions were determined for the studied species. Journal of Vector Ecology 38 (1): 90-96. 2013.

“…2,3 The genus Triatoma is of epidemiological importance because most vector species transferring T. cruzi to humans belong to this genus, an example is Triatoma infestans, considered the main domiciled species. 4,5 In Latin American countries, Chagas disease is considered an important cause of death and affects between six and seven million people. 6 Vector-borne transmission of T. cruzi may occur through one of the 148 triatomine species.…”

Chagas disease affects between six and seven million people. Its etiological agent, , is classified into six discrete typing units (DTUs). The biological study of 11 strains presented here included four parameters: growth kinetics, parasitemia curves, rate of macrophage infection, and serology to evaluate IgM, total IgG, IgG1, IgG2a, and IgG3. Sequencing of small subunit of ribosomal RNA (SSU rRNA)was performed and the strains were classified into three DTUs. When their growth in liver infusion tryptose medium was represented in curves, differences among the strains could be noted. The parasitemia profile varied among the strains from the TcI, TcII, and TcIII groups, and the 11 strains produced distinct parasitemia levels in infected BALB/c. The TcI group presented the highest rate of macrophage infection by amastigotes, followed by TcII and TcIII. Reactivity to immunoglobulins was observed in the TcI, TcII, and TcIII; all the animals infected with the different strains of showed anti- antibodies. The molecular study presented here resulted in the classification of the strains into the TcI (Bolivia, T lenti, Tm, SC90); TcII (Famema, SC96, SI8, Y); and TcIII (QMM3, QMM5, SI5) groups. These biological and molecular results from 11 strains clarified the factors involved in the biology of the parasite and its hosts. The collection of triatomine (vector) species, and the study of geographic distribution, as well as biological and molecular characterization of the parasite, will contribute to the reporting and surveillance measures in Brazilian states.
