Abstract:
Objective: To determine the prevalence of hydatidosis in dromedaries.Methods:2011. The relationship between host age and the mean number of hydatid cysts, and prevalence and fertility rates was analyzed using chi-square test.Results:438 dromedaries were examined in five regions of Iran from 20 March, 2010 to 19 March, Echinococcus granulosus. Number of cysts was 700 with 72.5% lung cyst. The highest rate of infection was that 54 (40%) of camels was found in the Khorasan Razavi region (in the north-east part of Iran) while the lowest 6 (4.4%) of camels was found in Semnan province. Infection was higher in >15 years age group. The most commonly infected organs were lungs (72.5%) followed by liver (12.6%). Both liver and lungs together constituted 14.8% of infection. A comparison found that hydatid cysts of liver had a higher fertility rate (32.57%) than that of lung (19%); while most of cysts of lung were calcified (24.42%). The mean number of protoscoleces per mL in the lung fertile cysts was higher than that of liver cysts. Fertile or sterile might be due to the different species or genotypes. The mean number of cysts in infected liver and lungs was 1-5 cysts. The intensity of infection increased with age.Conclusions:The results of current study can make a background data for implementing hydatid One hundred and thirty five out of 438 (30.82%) camels harboured hydatid cysts of control programs and warrant the importance of camel in public health.
