Quantitative assessment of hemadsorption by myxoviruses: virus hemadsorption assay.
The standardization and quantitative evaluation of an assay for myxoviruses, based on the enumeration of individual infected clone 1-5C-4 cells manifesting hemadsorption within 24 h of infection, are described. Hemadsorption was detectable earlier than immunofluorescence in infected cells or hemagglutinins in culture medium. The relationship between virus concentration and cells exhibiting hema...
متن کاملQuantitative Assessment of Mycoplasma Hemadsorption Activity by Flow Cytometry
A number of adherent mycoplasmas have developed highly complex polar structures that are involved in diverse aspects of the biology of these microorganisms and play a key role as virulence factors by promoting adhesion to host cells in the first stages of infection. Attachment activity of mycoplasma cells has been traditionally investigated by determining their hemadsorption ability to red bloo...
متن کاملHemadsorption of mumps virus examined by light and electron microscopy.
The hemadsorption (HAD) reaction of chick embryo cells infected with mumps virus was studied by means of light and electron microscopy, with special reference to the plasma membrane of the infected cell. The concomitant observation of membrane-free aggregates of viral nucleocapsid in the cytoplasm and attached red blood cells on the surface of the same cell indicated that only infected cells he...
متن کاملTitration of Newcastle disease virus and its neutralizing antibodies in microplates by a modified hemadsorption and hemadsorption inhibition method.
Using the microtiter system, titration of Newcastle disease virus infectivity and neutralizing antibodies was carried out in chicken embryo fibroblasts grown in "U" or flat-bottomed plates. Infectivity was detected by a combined hemadsorption-hemagglutination method. Inhibition of that reaction indicated the presence of neutralizing antibodies. A 24-h microneutralization test was developed and ...
متن کاملSolid-phase antibody capture hemadsorption assay for detection of hepatitis A virus immunoglobulin M antibodies.
A solid-phase antibody capture hemadsorption (SPACH) assay was developed to detect hepatitis A virus (HAV)-specific immunoglobulin M (IgM) antibodies in sera from humans recently infected with hepatitis. The assay is performed with microtiter plates coated with anti-human IgM antibodies to capture IgM antibodies from the test sera. HAV-specific IgM antibody is detected by the addition of HAV he...
