Antibodies in human sera reacting with an insect pathogenic virus
Intervirology
|January 1, 1979
Abstract:
Precipitating antibodies to an insect pathogenic RNA virus of Darna trima from East Malaysia have been found in a small percentage of human sera from several different groups of persons in West Malaysia and the United Kingdom. No associated illness was identified. The results suggest that an antigenically related virus or viruses are present in the environment that may be associated with symptomless or inapparent infections in man.
Insights
Antibodies to an insect virus were detected in human blood samples from Malaysia and the UK. These findings suggest widespread, symptomless infections from related viruses in the environment.
Area of Science:
- Virology
- Immunology
- Epidemiology
Background:
- Insect pathogenic viruses can potentially cross species barriers.
- Darna trima is an insect pest found in East Malaysia.
Purpose of the Study:
- To investigate the presence of antibodies to an insect pathogenic RNA virus (Darna trima) in human populations.
- To explore potential human exposure to antigenically related viruses.
Main Methods:
- Precipitin antibody testing was performed on human serum samples.
- Sera were collected from individuals in West Malaysia and the United Kingdom.
Main Results:
- Precipitating antibodies to the Darna trima virus were found in a small percentage of human sera.
- Antibody prevalence was observed in both Malaysian and UK populations.
- No specific illness was associated with the presence of these antibodies.
Conclusions:
- The study suggests the circulation of antigenically related viruses in the environment.
- These viruses may cause inapparent or asymptomatic infections in humans.
- Further research is needed to identify the specific viruses and understand their public health implications.
