[An analysis of the gene coding for the basic neutralizing antigen VP7 of human rotavirus isolate 1407].

A procedure based on polymerase chain reaction was developed for the study of rotaviruses. A full-length cDNA copy of the gene coding for major neutralizing glycoprotein VP7 of a human rotavirus isolate 1407 with the "long" electrophoretype (classified as the first electrophoretype) was cloned and sequenced. The primary structure of glycoprotein VP7 of isolate 1407 in A and C antigenic regions was found to be similar to that of serotype 1 virus.
