Abstract
Cystic echinococcosis (CE) is one of the most important zoonotic diseases in different geographical areas of the world including Iran. The current study aimed to assess the seroprevalence of human cystic echinococcosis (CE) in healthy blood donors in Fars province, southern Iran. A total of 1068 serum samples were collected from blood donors from five blood service centers of Fars province in south of Iran. Antigen B was prepared from sheep hydatid cyst fluid and collected sera were evaluated for anti-hydatid cyst antibodies, using antigen-B ELISA. Demographic features of the participants were also recorded during the sample collection. Anti hydatid cyst antibodies were detected in sera of 60 out of 1068 blood donors corresponding to overall seroprevalence of 5.6% in this population. Rate of seroprevalence was 6.7% in females and 5.5% in males. The highest rate of infection (8.3%) was found in age group of higher than 50years old. There were no significant differences between seropositivity to CE and sex, age or place of residence of the participants (P>0.05). Findings of this study showed that the rate of CE infection in Fars province, southern Iran, is relatively high. Some of these seropositive cases may have active hydatid cyst in their tissues without overt sign or symptoms.
