Antigen Detection in the Diagnosis of Viral Infections

Scandinavian Journal of Infectious Diseases, 1988
The value of viral antigen detection from nasopharyngeal secretion (NPS) by enzyme immunoassay (EIA) in everyday clinical practice was evaluated in 570 children hospitalized because of infections. NPS-EIA gave a positive result in 32% of all cases.

Relationship of hepatitis A antigen to viral hepatitis

The American Journal of the Medical Sciences, 1975
Progress in research on hepatitis type A has begun to accelerate because of the recent discovery of an antigen associated specifically with hepatitis type A infection and the development of tests for antibody to the antigen. Hepatitis A antigen is associated with 27 nm virus-like particles found in the liver and stool of animals experimentally infected

Antibody Response to Viral Antigens

1973
Publisher Summary This chapter focuses on humoral antibody response. It describes the general nature of viral antigens, what is being determined by seriological procedures applied to virus systems, the appraisal of such data for diagnostic and vaccine evaluation purposes, and the nature of the antibody response and some potential implications to ...

Australia Antigen, an Antigen Associated with Viral Hepatitis

1972
The long history of epidemic jaundice and the outbreaks of hepatitis which followed the introduction of large-scale parenteral therapy in venereal disease clinics, diabetic clinics, tuberculosis sanatoria and immunization centres, and hepatitis associated with the transfusion of blood and blood products, have recently been reviewed (Zuckerman, 1970a ...

Immunolabeling of Viral Antigens in Infected Cells

1991
Since its introduction in 1971 [2], labeling of antigens with gold particles to facilitate the detection of these antigens in thin sections of infected tissue by electron microscopy has proven to be a powerful technique. Also in plant pathology and especially in plant virology [4], this detection system has been applied frequently, enabling studies ...

Viral Hepatitis and the Australia-SH Antigen

Nature, 1969
Recent work has shed new light on an old disease. Australia antigen seems to be associated with small spherical particles which could be the agents of hepatitis.

Detection of Hepatitis a Viral Antigen by Radioimmunoassay

The Journal of Immunology, 1975
Abstract In 1973, Feinstone et al. (1), with the technique of immune electron microscopy (IEM)2 (2), detected virus particles in acute-phase stool suspensions obtained from patients with type A hepatitis. This technique was useful in further characterizing hepatitis A virus, but required the expertise of a skilled electron microscopist ...

Pathogenesis of viral encephalitis: Demonstration of viral antigen(s) in the brain endothelium

Acta Neuropathologica, 1983
One of the enigmas in the pathogenesis of inflammation is why the white cells adhere to the endothelium. In trying to define the pathogenic mechanism, we carried out experiments on ferrets infected with an SSPE strain of measles virus. Using immunoperoxidase labeling techniques, viral antigens were demonstrated on the luminal surface and in the ...

Viral diagnosis by antigen detection techniques

Clinical and Diagnostic Virology, 1996
Diagnosis of viral infections can be obtained in the early stages of a disease by detection of viral antigens directly in the clinical specimen. This has become an important tool for rapid virus diagnosis.Antigens produced during virus infections can be detected either in cells collected from the site of infection by immunohistological investigation or

Australia Antigen and Viral Hepatitis in Drug Abusers

Archives of Internal Medicine, 1971
Much evidence supports the hypothesis that Australia antigen (Au[1]) causes viral hepatitis. We found Au(1) in 30 of 43 drug abusers with hepatitis (69.8%), a similar frequency to posttransfusion hepatitis (56.3%), but different from infectious hepatitis (30.1%). There were no distinctive histologic features in liver biopsies from drug abusers.
