Micro diffusion precipitin tests for enteroviruses and influenza B virus
Abstract:
Middleton, G. K., Jr. (Bowman Gray School of Medicine, Winston-Salem, N.C.), H. G. Cramblett, H. L. Moffet, J. P. Black, and H. Shulenberger. Micro diffusion precipitin tests for enteroviruses and influenza B virus. J. Bacteriol. 87:1171-1176. 1964.-A simple micro precipitin gel diffusion test has been adapted to the study of viral antigens. As far as is known from a review of recent literature, this is the first use of the ECHO viruses in precipitin tests and the first attempt to demonstrate by the gel diffusion technique precipitins in a patient's serum after natural virus infection rather than artificial immunization. The principal value of this technique in virology is the rapid identification or qualitative analysis of viral antigen preparations by use of pooled or specific hyperimmune sera. Virus concentrations of 10(7)tcid(50) per 0.1 ml are required for reliable results, but only 0.015 ml of serum is necessary for each test. Virus-serum precipitin reactions were type-specific except for reciprocal precipitation of ECHO 1 and ECHO 8 by their hyperimmune sera. No viral antigens have been found common to two or more virus types among those tested. Precipitins for viral antigens occur frequently in serum of patients after a viral infection and are readily detected by micro precipitin gel diffusion tests. However, this precipitin test remains at present a tool for virus and antigen identification and offers an approach for research appraisal of host response to infections.
Insights
This study introduces a micro precipitin gel diffusion test for identifying viral antigens, including ECHO viruses. The test rapidly detects viral precipitins in patient serum after natural infections.
Area of Science:
- Virology
- Immunology
- Microbiology
Background:
- Viral antigen identification is crucial for diagnostics and research.
- Traditional methods for detecting viral precipitins can be time-consuming.
- The need for rapid and sensitive techniques for viral analysis is ongoing.
Purpose of the Study:
- To adapt and evaluate a micro precipitin gel diffusion test for studying viral antigens.
- To assess the utility of this technique for identifying enteroviruses and influenza B virus.
- To investigate the detection of precipitins in serum following natural viral infections.
Main Methods:
- A simple micro precipitin gel diffusion test was employed.
- The test was used to study viral antigens from enteroviruses (including ECHO viruses) and influenza B virus.
- Serum samples from patients with natural viral infections were analyzed.
Main Results:
- The micro precipitin gel diffusion test demonstrated type-specific reactions for most viruses tested.
- Reciprocal precipitation was observed between ECHO 1 and ECHO 8 viruses.
- Precipitins for viral antigens were frequently detected in patient serum after infection.
