Abstract

Hydatid cyst infected lung and liver specimens (60 and 10 respectively) of camel calves (about 12-18 months old) were collected from Kerdasa abattoir, Giza governorate during the period from January to August 2004. These specimens were subjected to parasitological and pathological examinations. Blood sample was also taken from each camel calf for serological study. Parasitological results revealed that, the infection rate with hydatid cysts in lungs was more than liver and the fertility of these cysts was 75% in lungs and 60% in liver. Serological results proved that, there were variable degrees of positivity that parallel correlate with gross findings of infected lungs ‘and liver with hydatid cysts indicating different stages of parasitic infection. Pathological findings showed a significant host tissue response in the form of mononuclear cell infiltration and fibroblastic proliferation (medium sized cysts). In addition, the tissue surrounds the fertile cysts revealed hyalinization.
The study concluded that, histopathological and serological examinations must be applied in hydatid cyst control programmes particularly in young animals.
