[biotic and abiotic determinants of seroprevalence of antibodies against trypanosoma cruzi in palmar de bravo, puebla, mexico].to establish the relationship between seroprevalence for antibodies against trypanosoma cruzi and its relationship with biotic and abiotic factors.200415053395
[heterogeneous distribution of the prevalence of anti-trypanosoma cruzi antibodies among blood donors in the state of puebla, mexico].to determine the seroprevalence and associated factors, of antibodies against trypanosoma cruzi (t. cruzi ab) among blood donors living in rural and suburban areas and risk regions.200515889637
clinical forms of trypanosoma cruzi infected individuals in the chronic phase of chagas disease in puebla, mexico.in mexico, despite the relatively high seroprevalence of trypanosoma cruzi infection in humans in some areas, reported morbidity of chagas disease is not clear. we determined clinical stage in 71 individuals seropositive to t. cruzi in the state of puebla, mexico, an area endemic for chagas disease with a reported seroprevalence of 7.7%. diagnosis of chagas disease was made by two standardized serological tests (elisa, iha). individuals were stratified according to clinical studies. all patients ...200617160280
high prevalence anti-trypanosoma cruzi antibodies, among blood donors in the state of puebla, a non-endemic area of mexico.blood transfusion is the second most common transmission route of chagas disease in many latin american countries. in mexico, the prevalence of chagas disease and impact of transfusion of trypanosoma cruzi-contaminated blood is not clear. we determined the seropositivity to t. cruzi in a representative random sample, of 2,140 blood donors (1,423 men and 647 women, aged 19-65 years), from a non-endemic state of almost 5 millions of inhabitants by the indirect hemagglutination (iha) and enzyme lin ...200212471419
lethal effects of a mexican beauveria bassiana (balsamo) strain against meccus pallidipennis (stal).the entomopathogenic fungus beauveria bassiana (balsamo 1835) vuillemin is an effective alternative control agent against some agricultural pests and biological vectors of important diseases such as chagas disease. in this work we studied an isolate of beauveria bassiana from of the town of san antonio rayón, puebla, mexico and its entomopathogenic effects on meccus pallidipennis (stal 1872). phylogenetic analysis using molecular comparison of the its and ef1α genes, showed that the resulting cl ...201425242941
[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.200617091798
predicting geographic and ecological distributions of triatomine species in the southern mexican state of puebla using ecological niche modeling.we analyzed the geographic distribution using ecological niche modeling of three species of triatomines distributed in the mexican state of puebla. punctual records were gathered for a period of 5 yr of fieldwork sampling. we used the genetic algorithm for rule-set production (garp) to achieve the potential distribution of the ecological niche of triatomines. the models showed that triatoma barberi and meccus pallidipennis are sympatric and widely distributed in the central-southern part of the ...200818533450
