PREVALENCE AND HISTOPATHOLOGICAL STUDIES OF HYDATID CYST IN CAMELS SLAUGHTERED AT AL-MUTHANNA PROVINCE

The aim of this study was to determine the prevalence and incidence of cystic echinococcosis among the camels slaughtered. Also, our study includes investigate the viability of protoscoleces and histopathological change evaluation. The result of current study revealed that only 29 out of 432 examined camels were infected with hydatid cyst at infection rate of (6.71%). There were a relationship between the climatic conditions and the incidence of Hydatidosis with a highest (14.03%) and lower (2.7%) percentages of infection in February and May respectively. Additionally, the highest (9.35%) and the lowest (3.37%) percentages of infection were recorded in 6-9 years, and 1-3 years respectively. According to sex, infection percentages were (10.69 %) and (4.39%) for female and male respectively. In addition, out of 73 cysts examined, 23 (31.5%) were sterile, 28 (38.3%) calcified and 22(30.1%) fertile out of which 8 (36.3.4%, 8/22) were viable cysts. on the other side, the result of histopathological examination were observed the changes in the lungs which include cellular infiltration lymphocytes and plasma cells, alveolar edema, mild congestion and slight spot hemorrhage and compression of bronchioles adjacent the cyst wall. Also, the histopathological changes in the liver were observed atrophy and mild hepatocellular degeneration in the liver tissue of around the capsule, leucocyte infiltration and hyperplasia of the bile ducts and dilatation in the sinusoids
