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
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
first molecular evidence of new bartonella spp. in fleas and a tick from peru.fleas, lice, and ticks collected in peru in a suburban area of cusco in november 1998 were tested by polymerase chain reaction for the presence of bartonella dna using primers amplifying a fragment of the intergenic spacer region (its) gene. three new bartonella genotypes were detected in pulex fleas self-collected from the beds and clothes of schoolchildren and adults. a fourth new genotype was also detected from a tick found on a sheep in the same area. one of the genotypes is closely related ...200212389935
