| sylvatic focus of chagas' disease in oaxaca, mexico. | during three field trips to the community of 'la humedad', municipality of santiago jamiltepec, oaxaca (a state in the southern part of the mexican republic), live specimens of triatoma mazzottii usinger (hemiptera: reduviidae) were found infected with trypanosoma cruzi. the insects were captured in only one of the dwellings inspected in the locality, and in four small caves where bats and other mammals live. these findings suggest the need for further studies on the existence of a sylvatic cycl ... | 1989 | 2513783 |
| distribution of domestic triatominae and stratification of chagas disease transmission in oaxaca, mexico. | mexico has 18 species of triatomine bugs (hemiptera: reduviidae) reported to be vectors of trypanosoma cruzi. chagas disease is widespread in mexico, with up to 3.5% seropositivity of human transfusion blood. the state of oaxaca has the longest history of endemic chagas disease, based on acute and chronic case reports, and of entomological surveys in the country. however, the state health care services need more information on current risks of vector transmission. in order to identify and charac ... | 2000 | 10759308 |
| cuticular hydrocarbon variability among triatoma dimidiata (hemiptera: reduviidae) populations from mexico and guatemala. | the geographic variation in the cuticular hydrocarbon pattern among 11 populations of triatoma dimidiata latreille (hemiptera: reduviidae: triatominae) from different regions of mexico and guatemala, was studied using capillary gas chromatography. t. dimidiata populations were differentiated based on the relative amounts of 71 hydrocarbon components. insect population classification was mostly in agreement with their geographical vicinity; mexican populations from the yucatan peninsula grouped t ... | 2005 | 16363161 |
| entomological indices, feeding sources, and molecular identification of triatoma phyllosoma (hemiptera: reduviidae) one of the main vectors of chagas disease in the istmo de tehuantepec, oaxaca, mexico. | the purpose of this study was to conduct an entomological analysis, determination of feeding sources, and molecular identification of triatomines in five communities of the istmo de tehuantepec, oaxaca. the only found species in two of five searched communities (san mateo del mar and tehuantepec city) was triatoma phyllosoma. colonization indices were high in both communities. in san mateo del mar, the insects were found indoors and in tehuantepec city in peridomestic areas. the trypanosoma cruz ... | 2011 | 21896810 |
