Aggiornamenti epidemiologici sull’echinococcosi animale in Italia

Cystic Echinococcosis (CE) is one of the
most widespread parasitoses in the Mediterranean Region (MR). This is due to various factors, the most important being the close association between man, sheep and dogs in areas where open farming is practised.
Although this disease has been known for several years and many studies have been carried out, nowadays in Italy there are no complete epidemiological data on its diffusion and distribution. The available data show that CE is mainly diffused in those districts where the sheep-dog cycle can be perpetuated, such
as central and southern Italy, and the islands. Furthermore, no data are available on biomolecular characterisation
of the strains ofEchinococcus granulosusin Italy, apart form those in Sardinia, where the G1
(sheep-dog) and G7 (pig-dog) strains were recently isolated. One of the reasons why CE is a problem with
no easy solution is undoubtedly the difficulty of making a certain diagnosis in the dog, the principal definitive
host ofE. granulosus.
