ABSTRACT
OBJECTIVES: The present study was performed to determine the seroprevalence of Toxocara in children ≤ 10 years old, from rural and urban areas of Ilam. METHODS: Serum samples from 383 children ≤ 10 years old, were selected randomly from rural and urban areas of Ilam province and surveyed using enzyme-linked immunosorbent assays. RESULTS: The total rate of infection with Toxocara was 22% (31% with a history of contact with dogs and cats, and 14% without a history of contact). Of those infected, 23% were male and 18% were female, 36% lived a rural life and 20% had an urban life. A significant correlation was found between the incidence of disease, and urban and rural life, as well as exposure to dogs and cats. There was no correlation between prevalence and gender or age. CONCLUSION: Given the high prevalence of infection with Toxocara amongst children in Ilam province, preventive work in the community such as education in risk management and periodic treatment with anti-parasitic drugs and elimination of stray dogs and cats is an appropriate measure.

OBJECTIVE@#To immunize rabbits with 12 and 16 kDa recombinant subunits of antigen B from Echinococcus granulosus (E. granulosus) and measuring polyclonal antibody and humoral immune response using ELISA and gel diffusion.@*METHODS@#Two mentioned antigens were cloned and expressed in expression vector and purified by affinity chromatography. Four young rabbits were selected and challenged intradermally with yielded recombinant antigens. Rabbits' sera were collected post infection and were tested using ELISA and gel diffusion for polyclonal antibody detection 10 days after last injection.@*RESULTS@#The specific antibody against the recombinant peptides was efficiently produced within 4 weeks post infection.@*CONCLUSIONS@#Produced recombinants proteins could induce the immune response of the rabbits successfully. This process might improve the clarification of diagnosis and vaccination as regards hydatidosis.
