molecular identification of echinococcus isolates from peru.genetic variations in tapeworms causing cystic echinococcosis in peru were investigated. seventy one larval isolates collected from different intermediate hosts and geographic regions were identified by the dna sequencing of genes for mitochondrial cytochrome c oxidase subunit 1 (cox1) and nuclear elongation factor 1 alpha (ef1a). the g7 genotype (e. canadensis pig strain) was found for the first time in pigs reared in the city of lima. echinococcus granulosus sensu stricto (sheep strain or g1) ...200919567235

notes on human cases of cystic echinococcosis in peru.cystic echinococcosis (ce) is a high prevalent zoonosis in the central and southern peruvian andes. serum samples (n50)from patients presenting presumptive clinical and radiological diagnosis of ce (group 1), were tested for antibodies against echinococcus granulosus metacestode using arc-5 double diffusion assay (dd5), immunoelectrophoresis (ief), and immunoelectrotransfer blot (eitb) techniques. serum samples (n18) from patients presenting other parasite infections (paragonomiasis, cysticercos ...200616862333
short report: endemic focus of cystic echinococcosis in a coastal city of evidence of echinococcus granulosus infection has been described in the coastal region of peru, with the exception of the capital city of lima. anecdotal evidence suggests the existence of a focus of echinococcosis in the coastal city of chincha, located south of lima. we conducted a preliminary epidemiologic study in chincha, which included an ultrasound, chest radiography, and serologic survey of abattoir workers, a review of medical records from local hospitals, and examination of the inte ...200415381815
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
human and canine echinococcosis infection in informal, unlicensed abattoirs in lima, peru.echinococcus granulosus infections are a major public health problem in livestock-raising regions around the world. the life cycle of this tapeworm is sustained between dogs (definitive host, canine echinococcosis), and herbivores (intermediary host, cystic hydatid disease). humans may also develop cystic hydatid disease. echinococcosis is endemic in rural areas of peru; nevertheless, its presence or the extension of the problem in urban areas is basically unknown. migration into lima, an 8-mill ...201222509413
