| genetic variation, population structure, and phylogenetic relationships of triatoma rubida and t. recurva (hemiptera: reduviidae: triatominae) from the sonoran desert, insect vectors of the chagas' disease parasite trypanosoma cruzi. | nucleotide and amino acid sequence data from the mitochondrial cytochrome b (cytb) and cytochrome c oxidase subunit i (coi) gene segments were used to gain insights into the population biology and phylogenetic relationships of two species of hematophagous kissing bugs (hemiptera: reduviidae: triatominae) from the sonoran desert of northwestern mexico and southern arizona, usa, triatoma rubida (uhler, 1894) and t. recurva (stål, 1868), both of which are vectors of the protozoan parasite trypanoso ... | 2006 | 16934496 |
| infection rates in dipetalogaster maximus (reduviidae: triatominae) by trypanosoma cruzi in the cape region, baja california sur, méxico. | infection rates of trypanosoma cruzi chagas (in the blood-sucking bug dipetalogaster maximus [uhler]) were determined from specimens collected at 12 localities in the cape region of baja california sur, mexico. eight collection sites were located in the tropical dry forest, two in desert shrub, and two in the ecotone between these two communities. of the 245 d. maximus collected, 65% were first and second instar nymphs; 32.6% were third, fourth, and fifth instar nymphs; and 2.4% were adults. the ... | 2003 | 12597648 |
| [seroepidemiology of chagas disease in mexico]. | the lack of information about chagas disease in mexico, as well as the controversy concerning its importance, was the basis for the seroprevalence study of trypanosoma cruzi in the national seroepidemiology survey (nss). this information was representative of the national situation with regard to disease prevalences and other factors related to the nation's health. unfortunately the nss was not a very good information source for the study of trypanosomiasis americana, because its coverage in the ... | 1992 | 1631732 |
