Polycystic Echinococcosis

Neotropical Echinococcosis: A Review

“…E. vogeli was responsible for causing more than 240 cases of human EP disease in several countries of Latin America [7,22], and even few cases of EP have been diagnosed in the Netherlands from Suriname people who had moved to this European country [22]. The diagnosis of this neotropical echinococcosis originally has been carried out by the morphology of the cestodes shape, size, and length of the large and small rostellar hooks of these two Echinococcus cestodes [7]; however, the diagnosis has been widely improved in the last two decades: first, by the use of immunodiagnostic techniques such as ELISA, Western blot, or immunoeletrophoresis; second by molecular techniques (PCR) [22][23][24][25][26] and third by the use of imagenology equipment, i.e., ecography, including ultrasonography, Computerized Axial Tomography (CAT), Magnetic Resonance Imagenology (MRI), and conventional radiography; all are important for the diagnosis of CE; all these techniques are used not only for classification and identification of cysts, but also for monitoring the responses to treatments [7,[27][28][29][30]; consequently, the number of human cases diagnosed has increased, not only in new cases, but it has also been reported in countries where it had not been diagnosed, i.e., Peru [30,31] and Argentina [32,33]. In addition, in the Peruvian Amazon, a study was carried out in wild pacas looking for EP, and 11.7% of pacas were found to be infected with metacestodes of E. vogeli, thus representing these pacas' potential risks for humans living in that Peruvian region and for rural and urban dogs [3,34].…”

“…Echincoccus vogeli is considered to be the most pathogenic species, responsible for a total of 179 reported human cases in the past four decades (Knapp et al , 2009; Siqueira et al , 2010; Zegarra et al , 2010). Echinococcus vogeli is transmitted between canines, such as bush dogs ( Speothos venaticus ) and domestic dogs ( Canis familiaris ), that harbour the adult tapeworm, and rodents, such as the Agouti paca , that harbour E. vogeli during the larval cestode stage (D'Alessandro & Rausch, 2008).…”
