[Serotyping of cytopathic rotavirus strains isolated from calves].

Antistrain sera were obtained against cytopathic rotavirus strains isolated from calves as well as against reference rotavirus strains, belonging to I and II serotype of the bovine rotaviruses with which cross antigenic studies were carried out. It was found that the isolated DS 39/82 and TR 248/82 strains belonged to I serotype of the bovine rotaviruses. Data was obtained speaking of some minor antigenic differences between strain TR 248/82 and strain DS 39/82 as well as between strain TR 248/82 and the reference rotavirus strain Lincoln (I serotype), which showed that there existed serologic variants between the strains of this serotype.
