Description
A cross-sectional study was conducted during four seasons from October 2009 to October 2010 to assess the status of cystic hydatidosis in the slaughtered camels at Kerman abattoir. Hydatid cyst count and characterization were conducted based on routine meat inspection. Out of the total 217 camels examined visually and manually by palpation and incision, 45 (20.73%) were found harboring hydatid cysts. A significantly higher infection was detected in older camels (P<0.05) than younger ones. Of the total 45 infected, 21 (46.66%) had hydatid cysts only in the lung, nine (20%) in the liver, while the rest 15 (33.33%) had multiple organ infections. Of the 62 viscera harboring hydatid cysts, the highest (58.06%) was the lungs followed by the liver (38.75%), and the spleen (3.22%). Size assessment made on 361 cysts indicated that 140 (38.78%) were small, 128 (35.45%) medium, 33 (9.14%) large, and 60 (16.62%) were calcified. The distribution of characterized cysts in different organs based on their size was found to be statistically significant (P<0.05). In addition, out of the total 361 cysts collected, 58.17% were fertile, 25.20% sterile, and 16.62% calcified or purulent cysts. The rate of cyst calcification was higher in the liver than in the lung .There was a significant difference in fertility of cyst from different organs (P<0.05), those of lung origin being highly fertile. Likewise, out of the 210 fertile cysts subjected for viability test, 120 (57.14%) were viable. The results showed that hydatidosis is one of the major parasitic diseases in the study area. In light of the result obtained and the current situation in Kerman Municipal abattoir and its surrounding, warranting serious attention for its prevention and control.
