Identification of group B rotavirus as an etiological agent in the gastroenteritis outbreak in Maharashtra, India.


ABSTRACT: Acute gastroenteritis outbreak occurred at Pargaon, Maharashtra, India in 1789 cases with an attack rate of 32.5% between November to December 2015. The stool specimens (n = 32) were investigated for different enteric viral agents using conventional methods. Transmission electron microscopy and RNA polyacrylamide gel electrophoresis respectively identified morphologically distinct rotavirus particles in 28% and RNA migration pattern of Group B Rotavirus (GBR) in 72% of the specimens. Reverse transcription polymerase chain reaction and nucleotide sequencing confirmed presence of GBR in 97% of the samples analyzed. The predominance of GBR infections and absence or insignificant presence of other agents confirmed GBR as an etiological agent of the gastroenteritis outbreak occurred in Maharashtra, India.
