| [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 |
| colonization of rock pile boundary walls in fields by sylvatic triatomines (hemiptera: reduviidae) in jalisco state, mexico. | granite rocks is a very abundant material in mexico because they are used habitually as borders for fields. the current work established the significance of this ecotype as a colonization site for triatomines of the phyllosoma complex. seven sites, arbitrary selected, in san martin de hidalgo municipality (mexico) were investigated in april 2002 by using 210 mouse bait-traps left during the night in wall hollows. one hundred and seventy-two triatomines of all life stages were collected from the ... | 2004 | 15185954 |
| [chronic chagasic cardiomyopathy at the hospital general de zona no. 24 imss. poza rica, veracruz]. | northern veracruz has conditions, biotic and abiotic, to support triatomine bugs and vectorial transmission of trypanosoma cruzi to human beings. therefore we explore seroprevalence of antibodies to this parasite and the presence of chronic chagasic cardiopathy (ccc) at cardiology ward in a general hospital serving north of veracruz state, and neighbord states hidalgo, puebla san luis potosi and tamaulipas. | 2006 | 17091798 |
| human infection and risk of transmission of chagas disease in hidalgo state, mexico. | new zones with risk of infection for chagas disease were reported in san antonio tezoquipan, caltimacan, and el ahorcado in the hidalgo state of mexico. antibodies to trypanosoma cruzi were detected by enzyme-linked immunosorbent assay and indirect hemagglutination assay in human serum samples. study subjects were also given an electrocardiogram. trypanosoma cruzi was isolated from triatomines collected and its virulence was determined in balb/c mice. seropositive persons were found in the three ... | 2007 | 17297042 |
| natural infection and distribution of triatomines (hemiptera: reduviidae) in the state of querétaro, mexico. | chagas disease is present in mexico but data on the presence of its vectors are not known for all the states. we conducted an epidemiological study to ascertain the presence of bedbugs in 23 communities of seven municipalities in the state of querétaro, mexico. sampling was performed within and outside dwellings, using the technique of one person searching per hour per house. four triatomine species were found: triatoma mexicana (94%), tri. dimidiata (3%), tri. gerstaeckeri (2%) and tri. pallidi ... | 2008 | 18589465 |
| [transmission risk of trypanosoma cruzi in metztitlán municipality from hidalgo state, méxico, by characterization of domiciliary units and their entomologic indexes]. | in order to determine the risk of transmission of trypanosoma cruzi by triatomines in metztitlan municipality, hidalgo state, mexico, entomological indexes were calculated and the characteristics of dwellings were described. a transversal, retrospective, descriptive, and observational study was performed by means of an intentional not probabilistic and expertise sampling from january to december of 2005 in 10 localities in which presence of triatomines were investigated either intra or peridomes ... | 2010 | 21120392 |
