Abstract
|
|
|
A basic survey of Echinococcus infection in cattle slaughtered at seogipo abattoir, Jeju Island was carried out.
The incidence of hydatid cyst was 0.4% in the native cattle, that is 4 heads out of 993 heads of the slaughtered cattle. The hydatid cysts with or without scolices were found in the liver and lung, and the speciation of them was determined as Echinococcus granulosus granulosus with the morphological and biological characters.
The infection rates of bovine echinococcosis were as high as 6.8% to 27.5% from 1936 to 1940 in Jeju cattle, but it has been found greatly decreased to 0.4% in this survey. The main reason of decrease in the incidence was cleared with the fact that wild dogs were abundant at that times.
