New tests for characterization of mumps virus antibodies: hemolysis inhibition, single radial immunodiffusion with immobilized virions, and mixed hemadsorption.

Comparison of Micro Neutralization Test with Hemadsorption-Inhibition Test, and Immunoflrorescence Technique for Detecting Mumps Antibodies

Hemolysis-in-gel and neutralization tests for determination of antibodies to mumps virus.

A hemolysis-in-gel test for the demonstration of antibodies to mumps virus is described. The results were compared with those of neutralization tests using a modified microtechnique. In the neutralization test viral replication was demonstrated by the hemadsorption of guinea pig erythrocytes, the visibility of which could be further enhanced by the use of o-tolidine. Good correlation was found ...

Udk 619:616.988.73:636.5 Examination of the Activity of Hn and F Glycoprotein Antigens of the Outer Envelope of Newcastle Disease Virus by Using Fusional, Hemolytic, Hemagglutination and Hemadsorption Tests, in Vitro

The objective of our study was to examine fusional, hemolytic, hemagglutination and hemadsorption activities of the surface glycoprotein HN and F antigens of Newcastle disease (ND) virus, in vitro. The samples of activated ND virions, induced Vero cell fusion after 6h, 12h, 24h and 48h. After 24h of treatment of the inoculated Vero cells with dilutions of the specific immune sera against ND vir...

Comparison of antibodies against different viruses in cerebrospinal fluid and serum samples from patients with multiple sclerosis.

The occurrence of a local production in the central nervous system (CNS) of antibodies against different selected viruses was analyzed by comparison of titers in serum and cerebrospinal fluid samples from groups of 50 patients with multiple sclerosis from Finland, Norway, and Sweden. Measles antibodies were determined in hemagglutination inhibition, hemolysis inhibition, and nucleocapsid comple...

Comparative measurement of equine influenza virus antibodies in horse sera by single radial hemolysis, neutralization, and hemagglutination inhibition tests.

Single radial hemolysis (SRH), neutralization (NT), and hemagglutination inhibition (HI) tests were carried out on sera from horses immunized against the Prague and Miami strains of equine influenza virus. The HI and NT tests demonstrated good sensitivity; the sensitivity of the SRH test was somewhat lower. The NT titers of individual sera were correlated very closely with the HI titers, althou...
