[Development of test systems of immunoenzyme analysis for the rapid diagnosis of rotavirus infection]

Area of Science:

• Virology
• Immunology
• Pediatrics

Background:

• Rotavirus is a common cause of acute gastroenteritis in children worldwide.
• Accurate and rapid diagnostic methods are crucial for effective patient management and epidemiological studies.
• Enzyme immunoassay (EIA) offers a sensitive platform for detecting viral antigens.

Purpose of the Study:

• To develop and evaluate a direct enzyme immunoassay (EIA) for detecting rotavirus antigen.
• To assess the prevalence of rotavirus antigen in stool specimens from children with acute enteric infections.

Main Methods:

• Development of a direct enzyme immunoassay (EIA) using simian rotavirus SA-11 and rabbit antiserum.
• Testing of stool specimens from 289 children with acute enteric infections and 56 healthy children.
• Analysis of antigen detection rates in relation to disease duration and clinical presentation.

Main Results:

• Rotavirus antigen was detected in 22.1% of children with acute enteric infections.
• Antigen was found in 3.5% of normal children, suggesting potential carrier states.
• Detection rates were highest within the first 3 days of illness and in cases of gastroenteritis.

Conclusions:

• The developed direct EIA is a viable method for detecting rotavirus antigen in pediatric stool samples.
• The findings highlight the significant role of rotavirus in acute childhood gastroenteritis.
• Further investigation into rotavirus carrier states and mixed infections is warranted.
