| 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 ... | 2007 | 16962710 |
| 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 ... | 2010 | 20944997 |
| echinococcus granulosus genotypes circulating in alpacas (lama pacos) and pigs (sus scrofa) from an endemic region in peru. | the identification of the genotypes of echinococcus granulosus present in livestock and wild animals within regions endemic for cystic echinococcosis (ce) is epidemiologically important. individual strains display different biological characteristics that contribute to outbreaks of ce and that must be taken into account in the design of intervention programs. in this study, samples of hydatid cysts due to e. granulosus were collected from alpacas (4) in puno and pigs (8) in ayacucho in peru, an ... | 2012 | 22415269 |
