| clinical and epidemiologic studies of chagas' disease in rural communities of oaxaca, mexico, and an eight-year followup: ii. chila. | a seroepidemiologic survey conducted in 1971 in the rural pacific coastal community of chila in the mexican state of oaxaca showed an unusually high prevalence of antibody against the chagas' disease agent trypanosoma cruzi. further studies were undertaken in 1973 and 1981 to (1) determine the pathologic impact of t. cruzi infection in humans, (2) investigate the natural history of the disease, (3) confirm that serologically positive persons were parasitologically positive, and (4) evaluate whet ... | 1992 | 1600437 |
| 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 |

| [american trypanosomiasis (chagas' disease). a clinico-serological survey in a rural community of oaxaca]. | a survey at a rural community in oaxaca, mexico revealed 30 (29%) out of 104 people tested are carriers of anti-trypanosoma cruzi antibodies. this high prevalence of seropositivity signals an important parasite circulation. we did not studied people under 15 years of age, therefore we can not identify transmission in this area. a concomitant study of 12 lead showed that those who are seropositive had more ekg abnormalities as a group. such findings could indicate the parasitic disease impact on ... | 1993 | 8503716 |
| 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 |
| [chagasic cardiopathy in tehuantepec. preliminary report]. | american trypanosomosis was described in the state of oaxaca, mexico in 1936, and is probably endemic in rural areas. however, there is no information regarding chronic disease in the isthmus of tehuantepec, previous to this report. | 2001 | 11565361 |
| mexican trypanosoma cruzi isolates: in vitro susceptibility of epimastigotes to anti-trypanosoma cruzi drugs and metacyclic forms to complement-mediated lysis. | trypanosoma cruzi has a clonal organization with an ample array of genetic and phenotypic features and probably anaploid constitution. consequently, the biological behavior, biochemistry, and molecular attributes may be distinctive for each parasite strain in different geographical regions. as far as we know, there is no published information on the susceptibility of mexican t. cruzi stocks to anti-t. cruzi drugs such as benznidazole and gentian violet, or on its resistance to complement-mediate ... | 2007 | 17760512 |
| 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 |

| maternal fetal transmission of trypanosoma cruzi: a problem of public health little studied in mexico. | the first case of neonatal chagas was reported in mexico in 1998, but there have been no studies since then. therefore, we investigated the rates of congenital infection of trypanosoma cruzi by examining the seroprevalence among 1448 pregnant women in oaxaca, jalisco and mexico city. we performed elisas to screen for recombinant and total antigens in mothers, and examined the frequency of congenital t. cruzi transmission by pcr with cord blood and antibody testing in children when they reached t ... | 2012 | 22683499 |
