Enzyme immunoassays (ELISA) have been developed for the detection of BK virus IgG- and IgM-antibodies. Specific IgG is detected by an antigen-coated solid phase test; IgM by an antibody capture method. These methods have been used to study the age-distribution of BK virus antibodies in Tromsø county in Northern Norway. The serum panels tested were: 60 sera from paediatric patients aged 0-1 year...

The microfabrication of electrochemical immunosensors for the simultaneous detection of two protein analytes is described. The sensors consisted of two iridium oxide electrodes (1-mm diameter) patterned on a glass substrate. Capture antibodies were immobilized on the porous iridium oxide electrodes by covalent attachment using (3-aminopropyl)triethoxysilane and glutaraldehyde. The spatial separ...

background and aims: toxoplasmosis is a parasitic disease which may cause some laboratory symptoms in infected individuals. one of the main ways of transmition this organism is placenta to fetus pathway. if this transmission occurs in the 3th month of pregnancy, the abortion, central nerve system and ocular disorder will happen. because of this issue, the precise technique for detection of toxo...

Study objective — assessment of the humoral and cell-mediated immunity features in COVID-19 convalescents three months after their discharge from hospital. Material Methods The study involved 78 who, depending on profile specific IgM IgG antibodies to SARS-CoV-2, were divided into groups. control group consisted 50 volunteers. Detection blood serum was performed by ELISA. Determination CRP conc...

In the present study, an enzyme-linked immunosorbent assay (ELISA) standardized with vesicular fluid of Taenia solium cysticerci was used to screen for IgG (total and subclasses) and IgE antibodies in cerebrospinal fluid (CSF) samples from patients with neurocysticercosis showing intrathecal production of specific IgG antibodies and patients with other neurological disorders. The following resu...

Early definitive diagnosis of dengue virus infection may help in the timely management of dengue virus infection. We evaluated the Standard Diagnostics (SD, South Korea) dengue virus nonstructural protein NS1 antigen enzyme-linked immunosorbent assay (SD dengue NS1 Ag ELISA) for the detection of dengue virus NS1 antigen in patients' sera, using a total of 399 serum samples in a comparison with ...

Taenia solium causes human neurocysticercosis and is endemic in underdeveloped countries where backyard pig keeping is common. Microscopic fecal diagnostic methods for human T. solium taeniasis are not very sensitive, and Taenia saginata and Taenia solium eggs are indistinguishable under the light microscope. Coproantigen (CoAg) ELISA methods are very sensitive, but currently only genus (Taenia...
