Abstract

 Background and objective: Cystic Echinococcosis (CE) is a cosmopolitan and prevalent zoonosis in the world. It caused by larva of Echinococcus genusspecies. CE is medically and economically one of the important parasitic zoonoses in Iran especially Moghan Plain. So far no survey was conducted to determine the rate of CE in this region.

 Method: The subjects of this descriptive- analytic study were people of the Moghan plain. The prevalence of the disease was determined with serologic examination using ELISA test. ELISA was carried out using HCF-Ag that obtained from a diseased sheep. Household information was recorded in questionnaires before collecting serum samples. The results were analyzed by SPSS using statistical tests.

 Result: Out of 2008 samples, 1267 were female and 734 were male. At all 9.2 % (184) of sera were found to be positive.

 Conclusion: This survey determined more prevalence of Cystic Echinococcosis in women (%10) than men (%7.9) and infection is more in places that keep much Dogs.

Abstract

Background & objectives: Alveolar and cystic echinococcosis (CE and AE) are caused by the larval stages of Echinococcus multilocularis and Echinococcus granolosus, respectively. This study was conducted to determine the spread of human AE and CE diseases among the tribes and livestock breeders and farmers in the Moghan plain. The prevalence of infection (CE and AE) significantly increases with a rise in age.
Methods: In this study, using ELISA and HCF-Ag (raw liquid antigen of hydatid cyst) was used for the first time to perform screening, and then the prevalence of cystic echinococcosis and alveolar echinococcosis was evaluated by specific anti-genes Ag-5 and EM2+, respectively. A total of 2003 serum samples were collected randomly from normal populations of five different areas of Moghan plain. In the first stage, serum screening was tested using an enzyme-linked immunosorbent assay and HCF-Ag. After that, the serology of all sera was evaluated by ELISA and specific antigens for alveolar and cystic Echinococcus.
Results: From 2003 samples, 24 serum samples were (1.19%) AE-positive. Infection was higher in men than women (2.1% vs. 0.6%). The age group of 5-19years had the lowest infection rate and the age group 40- 59 years had the highest infection rate (2%). In the case of cystic ecinococcosis, 164 serum samples were positive for Ag-5 specific antigen, i.e. 7.6% infection, and 156 serum samples were positive for Ag-B-specific antigen.
Conclusion: The findings showed that the highest infection rate was found in the Boran and Eivazlou (Palanglou) regions of Moghan plain and the lowest level of human infection was reported in Parsabad region (Nadar-kandi and Agh-ghabagh). In areas with higher contamination, the risk factor associated with CE and AE were the type of water used, the method of washing edible and wild vegetables, occupation and having or not having knowledge of hydatid disease. The infection of Moghan region dogs is one of the main indicators and potential risk factors for human infection.
