in this report, a seroepidemiological survey was performed to determine the prevalence of rubella immunity and antibody titer in 11-16 year old girls in urban and rural areas of tonkabon district in northern iran. the results and conclusion are presented.

A cultivable human rotavirus, Wa, was propagated in MA-104 cells and used as an antigen in immune adherence hemagglutination (IAHA) and complement fixation (CF) tests. IAHA antibody titers of sera from normal humans were found to be eightfold higher than CF antibody titers. The IAHA antibody determination with the Wa antigen is considered to be especially useful for the seroepidemiological stud...

Background & Aims: Hydatidosis as a parasitic zoonotic infection is endemic in Iran, but systematic information about the exact rate of hydatidosis prevalence in different regions of the country is very limited. Because of the importance of disease this study was undertaken in East-azarbaijan province to determine the prevalence rate of hydatidosis by ELISA method. Methods: Totally, 1500 serum ...

A seroepidemiological survey in coastal Croatia detected antibodies reactive with Rickettsia conorii in 4.2% of sera by immunofluorescence assay and in 5.0% of sera by enzyme immunoassay. Western immunoblotting demonstrated antibodies to the 120-kDa surface protein in all 20 positive serum samples examined and to rickettsial lipopolysaccharide in 3 of these serum samples. Humans in this area ar...
