| identification and biochemical characterization of leishmania strains isolated in peru, mexico, and spain. | eight leishmania promastigotes were isolated from different geographical areas: three (lp1, lp2, and lp3) from the provincial department la libertad and the fourth (lp4) from the department of cajamarca (northern peru); another three (lm1, lm2, and lm3) in the province of campeche (mexico); and the last (ls1) from a clinical case of a dog in madrid (spain). the isolates were characterized by carbohydrate cell-surface residues using agglutinations with four purified lectins, by isoenzyme analysis ... | 2006 | 16289175 |
| [indicators of infestation, colonization and infection of triatoma dimidiata (latreille) (hemiptera: reduviidae) in campeche, méxico]. | triatoma dimidiata (latreille) is considered to be one of the primary vectors of chagas disease in southern mexico and central america. the objective of the present study was to obtain ecological information on t. dimidiata in two rural communities of campeche, mexico, where the vector is poorly studied. our work consisted of monthly samplings carried out during one-year time at three levels: sylvatic, peridomestic and intradomestic, in order to estimate the population abundance of this species ... | 2010 | 21271074 |
| higher seroprevalence of trypanosoma cruzi infection in dogs than in humans in an urban area of campeche, mexico. | abstract the reservoir capacity of dogs for trypanosoma cruzi infection was analyzed in the city of campeche, an urban town located in the yucatan peninsula in mexico. the city is inhabited by ∼96,000 dogs and ∼168,000 humans; triatoma dimidiata is the only recognized vector. in the present study, we sampled 262 dogs (148 stray dogs and 114 pet dogs) and 2800 young people (ranging in age between 15 and 20 years old) and tested for t. cruzi antibodies by enzyme-linked immunosorbent assay, indirec ... | 2010 | 21028957 |
