| feeding behavior of triatomines from the southwestern united states: an update on potential risk for transmission of chagas disease. | chagas disease is an emerging infectious disease in north america due to the immigration of individuals from endemic areas. the parasite has been transmitted to patients in non-endemic areas by blood transfusion and organ donation. only six autochthonous cases have been described in humans in the united states yet the parasite is widespread among native mammals and resident triatomines are competent vectors. we attempted to determine if common southwestern triatomines, triatoma protracta and tri ... | 2009 | 19524078 |
| Feeding and defecation behavior of Triatoma rubida (Uhler, 1894) (Hemiptera: Reduviidae) under laboratory conditions, and its potential role as a vector of Chagas disease in Arizona, USA. | Chagas disease is caused by the parasite Trypanosoma cruzi, which is transmitted to humans by blood-sucking triatomine insects. This disease is endemic throughout Mexico and Central and South America, but only a few autochthonous cases have been reported in the United States, despite the fact that infected insects readily invade houses and feed on humans. Competent vectors defecate during or shortly after feeding so that infective feces contact the host. We thus studied the feeding and defecatio ... | 2011 | 21976567 |
| an insight into the sialotranscriptome of triatoma rubida (hemiptera: heteroptera). | the kissing bug triatoma rubida (uhler, 1894) is found in southwestern united states and parts of mexico where it is found infected with trypanosoma cruzi, invades human dwellings and causes allergies from their bites. although the protein salivary composition of several triatomine species is known, not a single salivary protein sequence is known from t. rubida. furthermore, the salivary diversity of related hematophagous arthropods is very large probably because of the immune pressure from thei ... | 0 | 22679863 |
