Electrophoretic Patterns of Human Rotavirus Strain Prevailing Among Children

Area of Science:

• Virology
• Pediatrics
• Public Health

Background:

• Rotavirus gastroenteritis is a leading cause of severe dehydrating diarrhea in children globally.
• Group A rotavirus accounts for a substantial proportion of childhood diarrhea hospitalizations.

Purpose of the Study:

• To detect and characterize rotavirus strains in hospitalized children in Bangladesh using PAGE.
• To investigate the genomic variations and epidemiological patterns of rotavirus infections in the study population.

Main Methods:

• Polyacrylamide gel electrophoresis (PAGE) and silver staining were employed to detect rotavirus double-stranded RNA (dsRNA).
• Stool specimens from 776 hospitalized children under five years old in Mymensingh, Bangladesh, were analyzed.
• Electropherotyping was used to classify viral RNA profiles into long and short patterns.

Main Results:

• A rotavirus prevalence of 47.4% (368/776) was detected using PAGE.
• Of the positive samples, 92.5% (341/368) allowed for electropherotype classification.
• The highest infection rates were observed in children aged 7-12 months, with a higher incidence during winter. Long RNA patterns (48%) and short RNA patterns (52%) were identified, along with 2% mixed electropherotypes.

Conclusions:

• PAGE is an effective method for studying rotavirus genomic variation and identifying mixed or atypical infections.
• The findings highlight the importance of rotavirus surveillance and provide insights into its epidemiology in Bangladesh.
