Between 1986 and 1993, 72% of rotavirus strains isolated from newborns
at five hospitals in New Delhi, India, had long electropherotypes, su
bgroup II VP6 antigens, and G and P genotypes (G(9)P(11)) identical to
those of prototype strain 116E. A novel strain with a G(9)P(6) genoty
pe, representing 13% of the isolates, was identified. These results de
monstrate that G(9)P(11) and G(9)P(6) rotavirus strains are common in
nurseries in New Delhi.
