Intestinal helminthiases in Ecuador: the relatíonship between prevalence, genetic, and socioeconomic factors

Prevalence of infection with the intestinal helminths, Ascaris lumbricoides, Trichuris trichiura, Ancylostoma duodenale and Strongyloides stercoralis was examinedin 632 residents of communities in Esmeraldas province of Ecuador. These communities were divided into two groups according to area of habitation which reflected different socioeconomic circumstances. Attempts were made to correlate infection status with race and ABO blood group phenotype. The racial groups included blacks, Chachi amerindians, and mixed-race mestizos. Greater prevalences of infection were seen in the area oflower socioeconomic status. No racial or blood group associations with helminth infection were seen controlling for socioeconomic status.

Severe digestive pathology associated with chronic Chaga's disease in Ecuador: report of two cases

DNA extracted from peripheral blood of two Ecuadorian patients showing severe digestive pathology was amplified by the polymerase chain reaction using a Trypanosoma cruzi specific oligonucleotide primers derived from the primary sequence of a cDNA encoding for a 24 kDa excretory/secretory protein. The positive PCR results together with the clinical findings confirmed that both patients had a digestive pathology due to Chagas' disease. This pathology could be more frequent than previously described in the chagasic endemic regions of Andean countries.

Control of intestinal helminths in schoolchildren in Low-Napo, Ecuador: impact of a two-year chemotherapy program

A school-based control program of intestinal helminths was undertaken among schoolchildren in the Low-Napo region, north-eastern Ecuador. Forty-eight percent of children were infected with one or more helminths at the first examination. The prevalence at the baseline was Ascaris 33.2% followed by hookworm 24.1% and Trichuris 6.5%. Sex was found to be a significant factor influencing the prevalence of hookworm and Trichuris. Prevalence was compared 9 months and 18 months after treatment. After 9 months, Ascaris and Trichuris prevalence had decreased but not hookworm. All of them increased after 18 months. The findings suggest that only a course of mebendazol had a minor effect on the control of helminth infections.

Andes ardientes. Etnia, conflicto y tramado institucional en Bolivia, Perú y Ecuador

La vuelta de la democracia ha permitido visibilizar a numerosos grupos étnicos que se encontraban oprimidos por las élites en el poder. Éstas, que han tradicionalmente cooptado el concepto de nación, mantienen un enfrentamiento con los grupos indígenas, con recientes accesos al poder. Este conflicto se ha manifestado en diferentes grados a lo largo de los años, yendo desde huelgas hasta conatos de guerra civil. Desde esta perspectiva, el presente proyecto se abocará a discernir las relaciones existentes entre identidad, emergencia étnica y conflicto en la región andina
