The article describes the geography, way of life, manners and customs, health education, and other characteristics of the population in the “Sierra” of Peru. We report a human case of polycystic hidatidosis due to Echinococcus vogeli from (Department of Loreto) village located in the central jungle of Peru. To determine the genotypes present in endemic areas of Peru, samples were .. Proyecto de control de hidatidosis en el Perú por vigilancia epidemiológica.

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 frompatients presenting presumptive clinical and radiological diagnosis of CE group 1were tested for antibodies against Echinococcus granulosus metacestode using Arc-5 hidaridosis diffusion assay DD5immunoelectrophoresis IEFand immunoelectrotransfer blot EITB techniques.

Serum samples n18 from patients presenting other parasite infections paragonomiasis, cysticercosis, and fascioliasis or healthy blood donors n15were designated as control groups. Only patients from group 1 were seropositive for CE.

Epidemiology of Echinococcus granulosus infection in the central Peruvian Andes.

Polypeptides of 21, 31, and 48 kDa were considered positive for CE. Echinococcus granulosus -cystic echinococcosis – human cases – Peru. Recently, a new transmission area was reported in the coastal region of Peru Moro et al. In this study, sera were tested for antibodies against Echinococcus granulosus metacestode in 50 individuals 29 females and 21 malespresenting presumptive clinical and radiological diagnosis for CE group 1.

The two controls groups were 18 serum samples from patients with other helminths Paragonimus sp. Hydatid cyst fluid HCF was obtained from lung and liver fertile cysts of sheep from abattoirs in Lima.


For the DD5 test, a titer of 1: Demographic and clinical data were obtained from each individual. The patients were from the departments Figure located in the coastal area of Peru: The informed consent was obtained prior to subject enrollment. Seropositivity for CE was only detected among serum samples from patients of group 1, and all patients who underwent surgery were seropositive.

The immunoblot assay revealed molecular masses of 21, 31, and 48 kDa bands, which are specific for the genus Echinococcus Romani Demographic information and clinical data hivatidosis summarized in the Table.

In despite of the importance of the enzyme-linked immunoelectrotransfer blot for the diagnosis of CE due to its high sensitivity, this study confirmed that the DD5 test is also hieatidosis due to its easy performance, low cost, and high specificity Verastegui et al.

The topography of Peru is highly varied, ranging from narrow coastal desert to high altitude sierra to Amazonian basin jungle, with gradations of intervening climatic zones Moro et al. Consequently, the epidemiology of cystic echinococcosis varies among endemic areas. The first coastal autochthonous cases of CE were recently reported hiadtidosis Chincha, a city located south of Lima Moro et al. In contrast to general findings that CE transmission enrolls agricultural and farming activities, in this study most seropositive patients were teachers, students, housewives, workmen, and civil hidaidosis.

The human migration process has health implication influencing the pattern of transmission into a new environment. Cystic echinococcosis is classified as rural disease, but its occurrence in urban areas has become significant due to hudatidosis introduction of E. An earlier survey demonstrated that the prevalence of canine infection ranges 3. Probably, other epidemiological risk factors as cohabiting with a great number of infected-dogs during the first years of life and using undrinkable water should also be stressed Larrieu et al.


The present results confirm that the cystic echinococcosis is a common infection in Peru; it seems that transmission also occurs in other coastal cities than Lima and Chincha.
