Infantile gastroenteritis virus
Abstract:
The authors demonstrated presence of virus particles of 55--75 nm manifesting morphological properties of the virus of infantile gastroenteritis (rotavirus, orbivirus, reo-like virus) by means of the electron microscopy, when investigating samples of stools of children sufferring from non-bacterial diarrheal diseases. Stool extracts were incubated with commercial gamma globulins or with convalescent sera provoking formation of extensive immunocomplexes. The complexes do not form when stool extracts are incubated with sera obtained from initial stages of the disease. This finding is an evidence of the presence of the virus in question among our population.
Insights
Researchers detected infantile gastroenteritis virus particles in children's stool samples using electron microscopy. This confirms the virus
Area of Science:
- Virology
- Pediatrics
- Immunology
Background:
- Non-bacterial diarrheal diseases are a significant concern in pediatric populations.
- Identifying the causative agents of infantile gastroenteritis is crucial for public health.
Purpose of the Study:
- To investigate the presence of virus particles associated with infantile gastroenteritis in children with non-bacterial diarrhea.
- To characterize the morphology of detected virus particles.
Main Methods:
- Electron microscopy was used to examine stool samples from children with non-bacterial diarrhea.
- Stool extracts were incubated with gamma globulins and convalescent sera to detect immunocomplex formation.
Main Results:
- Virus particles, 55-75 nm in size, with morphological characteristics of rotavirus, orbivirus, or reo-like viruses were identified.
- Incubation with convalescent sera and gamma globulins led to the formation of extensive immunocomplexes.
- No immunocomplexes formed when stool extracts were incubated with sera from the early stages of the disease.
Conclusions:
- The findings provide evidence for the presence of infantile gastroenteritis viruses within the studied population.
- Immunocomplex formation serves as a diagnostic indicator for the presence of these viruses.
