S. Gunasena et al., RELATIVE FREQUENCY OF VP4 GENE ALLELES AMONG HUMAN ROTAVIRUSES RECOVERED OVER A 10-YEAR PERIOD (1982-1991) FROM JAPANESE CHILDREN WITH DIARRHEA, Journal of clinical microbiology, 31(8), 1993, pp. 2195-2197
The relative frequencies of the Wa (corresponding to serotype P1A), DS
-1 (P1B), M37 (P2), and AU-1 (P3) alleles of the VP4 gene from rotavir
uses collected from the stools of individuals in Japan between 1982 an
d 1991 were determined to be 83.1, 15.6, 0, and 1.3%, respectively, by
a polymerase chain reaction-based typing assay.
