background and aims: cytomegalovirus (cmv) is a member of herpesviruses. it is one of the most common cause of congenital and prenatal infections. cmv infection of pregnant women, especially in the first trimester may lead to congenital abnormalities in the newborns. the prevalence of cmv infection in developed countries is about 40% and in developing countries may be 100%. because there is no ...
background: retroviruses of human t-lymphotropic viruses (htlv-1 and htlv-2) have been demonstrated to be endemic in the north-eastern region of iran. this study aims to determine htlv-1 and htlv-2 prevalence among healthy individuals in neyshabur city during 2010-2014. methods: a total of 8054 blood samples were collected from healthy participants in neyshabur, north-eastern iran. the blood sa...
The epidemiology of Toxoplasma gondii infection in pregnant women in rural Mexico is largely unknown. The seroepidemiology of T. gondii infection in 439 pregnant women from 9 communities in rural Durango State, Mexico was investigated. Using commercial enzyme-linked immunoassays, sera were tested for T. gondii IgG, IgM, and avidity antibodies. Prevalences of T. gondii IgG antibodies in the comm...
There is a lack of information about the seroepidemiology of T. gondii infection in the general population of Durango City, Mexico. Anti- Toxoplasma gondii IgG and IgM antibodies were sought in 974 inhabitants in Durango City, Mexico with the use of enzyme-linked immunoassays. in total, 59 (6.1%) of 974 participants (mean age 37 ± 16.1 yr) had IgG anti- T. gondii antibodies. Twenty (2.1%) of th...
To inform current and future vaccination strategies, we describe the seroepidemiology of hepatitis B virus (HBV) infection in ten representative European countries using standardized serology that allowed international comparisons. Between 1996 and 2003, national serum banks were compiled by collecting residual sera or by community sampling; sera were then tested by each country using its prefe...
Background and Aims: Some nanoparticles can be used in immunoassays to increase sensitivity. This study aimed to evaluate a novel nano-immunoassay based on bovine serum albumin nanoparticles (BSA NPs). Materials and methods: At first, the nanostructure was synthesized, and then applied as a tag in the nano-immunoassay. Then the concentration of β-subunit of human chorionic gonadotropin ...
