Group B Rotavirus Infections in Mymensingh, 2015.

Rotaviruses are the most important etiological agents of severe diarrheal illness in infants, children, and adults throughout the world. Group A rotavirus causes approximately 40% of hospitalization for diarrhea among under 5 years children. The prevalence of Group B rotaviruses is not as high as that of Group A. ICDDRB, in 2008 reported Group B rotaviruses as 2.4%. Polyacrylamide gel electrophoresis (PAGE) and silver staining was applied to detect rotavirus dsRNA from acute diarrheic stool of 364 hospitalized adult patients with mild to severe diarrhea. The study was conducted in Mymensingh district, Bangladesh from January 2013 to December 2014. Among 364 stool specimens tested 14(3.9%) were positive in adult by PAGE. Males were slightly higher than females and infection rate was more in winter. PAGE technique could be applied as an excellent method for studying different groups of rotavirus including Group B rotaviruses.
