intraspecific variation of echinococcus granulosus in livestock from peru.echinococcus granulosus infection is a problem of public health in livestock-rearing regions of latin america, like in peru. this species is characterized by the morphometry of the large and small rostellar hooks in both metacestodes and adult worms. the aim of this work was to study biometrical characteristics of rostellar hooks in hydatid cysts (lung and liver) from some peruvian provinces (arequipa, cuzco, huancavelica, junin and puno). the biometrical analysis was obtained in a digital syste ...200716962710
molecular characterization of echinococcus granulosus from peru by sequencing of the mitochondrial cytochrome c oxidase subunit 1 gene.echinococcus granulosus, the etiologic agent of cystic echinococcosis (ce) in humans and other animal species, is distributed worldwide. ten intra-specific variants, or genotypes (g1-g10), have been defined based on genetic diversity. to determine the genotypes present in endemic areas of peru, samples were collected from cattle (44), sheep (41) and humans (14) from junín, puno huancavelica, cusco, arequipa and ayacucho. dna was extracted from protoscolex and/or germinal layers derived from 99 e ...201020944997
distribution of hydatidosis and cysticercosis in different peruvian populations as demonstrated by an enzyme-linked immunoelectrotransfer blot (eitb) assay. the cysticercosis working group in peru (cwg).a serosurvey for human hydatidosis and cysticercosis was performed in different regions of peru. those regions included a known endemic area for cystic hydatid disease, a cooperative in the central peruvian andes near the city of tarma, department of junin; three areas endemic for cysticercosis in the departments of ancash, cuzco, and san martin, where the status of hydatid disease is not well defined; and an urban shantytown near lima, where neither zoonosis is known to be present. a seropreval ...19947810822
[household factors associated with the presence of human hydatid disease in three rural communities of junin, peru].hydatid disease, a zoonosis caused by the larval stage of the parasite echinococcus granulosus, is a public health problem at national level, especially in those regions dedicated to raising livestock. by now, there are many factors, at individual level, that have been associated to the infection by e. granulosus; nevertheless there is not any previous report that explore the association between household characteristics and the presence of the disease among household members.201021308187
