Prevalence and Histopathological Studies of Hydatid Cyst in camels slaughtered at Al-Muthanna Province

Abstract

The goal of this research was to evaluate the frequency and incidence of cystic echinococcosis among the camels slaughtered. Also, our study includes investigating the viability of protoscoleces and histopathological change evaluation. The result of the current study recorded only 29 of the 432 slaughtered camels were infected with hydatid cyst (6.71%). Occurrence of Hydatidosis was connected to climatic conditions, with a highest (14.03%) and lower (2.7%) proportion of infection in February and May respectively. In addition, the highest (9.35%) and the lowest (3.37%) proportions of infection were found in 6-9 years, and 1-3 years respectively. Infection rates were 10.69% for females and 4.39% for males, respectively, based on sex. Besides, 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. Furthermore, the histopathological examination was revealed alterations in the lungs, including  infiltration of plasma cells and lymphocytes, also alveolar edema, mild congestion, slight spot hemorrhage.  while, hyperplasia of  the bile ducts and leucocyte infiltration, as well as dilatation in the sinusoids, were seen as histological changes in liver. Also, these changes included atrophy and mild hepatocellular degeneration in liver around the capsule.
