[Detection of an agent similar to rotavirus in infantile gastroenteritis]
Abstract:
The etiology of nonbacterial enterovirus infections in children was studied in autumn and winter under conditions of focal outbreaks in Moscow hospitals. Electron microscopy revealed a reovirus-like agent in concentrated suspensions of feces collected in the acute period of the disease from children suffering from diarrhea. Examinations of paired sera from the patients by the CF test with the antigen of Nebraska calf disease virus established significant rises in antibody titers in 68.3% of cases. The results permit a conclusion that in this country a virus of acute gastroenteritis of children (viral gastroenteritis A) is circulating, causing outbreaks of the disease. The virus belongs to the genus Rotavirus of the Reoviridae family.
Insights
A reovirus-like agent, identified as rotavirus, was found to cause viral gastroenteritis outbreaks in Moscow children. This discovery confirmed the circulation of a significant pediatric enteric pathogen.
Area of Science:
- Virology
- Pediatrics
- Infectious Diseases
Context:
- Investigated nonbacterial enterovirus infections in children during hospital outbreaks in Moscow.
- Focused on cases occurring in autumn and winter seasons.
Purpose:
- To determine the etiology of acute gastroenteritis in children.
- To identify the causative agent responsible for outbreaks of viral gastroenteritis A.
Summary:
- Electron microscopy identified a reovirus-like agent in fecal samples from children with diarrhea.
- Complement fixation (CF) tests showed significant antibody titer increases against Nebraska calf disease virus in 68.3% of patients.
- The identified agent was classified as belonging to the genus Rotavirus, family Reoviridae.
Impact:
- Confirmed the circulation of a specific rotavirus strain causing pediatric gastroenteritis outbreaks in the region.
- Provided etiological insights into viral gastroenteritis in children, aiding in understanding disease transmission and control.
