“…Earlier works indicate the presence of at least two serotypes among group A bovine rotaviruses [2,3,9,15,21,26,32,35,36]. While the NCDV and UK strains have long been established as serotype 6 under the unified serotyping scheme, assignment of the bovine serotype 2 strains to a serotype under this scheme has just been taken into consideration.…”

Cross neutralization tests with a panel of rotavirus strains representing previously described nine VP7 (G) serotypes revealed that bovine rotavirus strain KK-3, a prototype Japanese bovine serotype 2, belonged to a new serotype (G10), confirming and extending the recent report of Snodgrass et al. [J. Clin. Microbiol. 28: 504-507 (1990)] which showed that hyperimmune serum to the KK-3 strain neutralized the B223 strain, a proposed type strain of G10. Further antigenic characteristics of the KK-3 strain, as well as the 0510 strain (a G6 strain isolated in Japan), were examined in terms of their VP4 (P) specificity. For the characterization of P types, we employed genetic reassortants that possess VP4 gene for UK and VP7 gene for D (G1), VP4 gene for NCDV and VP7 gene for SA11 (G3), or VP4 gene for SA11 and VP7 gene for NCDV (G6) in the plaque reduction neutralization assay with hyperimmune sera against these two Japanese strains and the prototype bovine rotavirus NCDV strain. While the 0510 strain had UK-like P and NCDV-like G types, the KK-3 strain had a distinct set of P and G types. Thus, at least three P types (NCDV-, UK-, and KK-3-like) and two G types (G6 and G10) are present among bovine rotavirus strains.

“…Serologically they are quite complex: to cite only two mammalian species, five serotypes have been identified among rotaviruses from children (Hoshino et al, 1984;Matsuno et al, 1985), and at least two serotypes have been isolated from calves (Bridget & Brown, 1984;Briissow et al, 1987 a;Ihara et al, 1983;Murakami et al, 1983 ;Ojeh et al, 1984;Woode et al, 1983). Two bovine rotavirus genes coding for two different outer shell proteins cosegregated with virus neutralization specificities (Offit & Blavat, 1986).…”

SUMMARYSingle serotype vaccination of mature cows with nine different strains of bovine, simian and human rotaviruses induced heterotypic milk and serum neutralizing antibodies against two bovine and four human rotavirus serotypes. Immunization with single-shelled simian rotavirus SA11 increased milk and serum neutralization titres fivefold over those of control cows, without inducing antibodies to outer shell polypeptides of rotavirus. Vaccination with double-shelled SA 11 virions also elicited cross-reacting antibodies to the outer shell proteins VP3 and/or VP7 which neutralized rotavirus seven times more efficiently than antisera to single-shelled SAIl virus. A related rotavirus similar to simian rotavirus SA 11, but from a different host, might thus be an attractive vaccine for immunization of pregnant cows to confer passive immunity to calves.

“…Several serotypes have been identified among rotaviruses ti:om children (2,36), calves (5,16,27,30,33,35), foals (13), piglets (3), mice (12) and avian species (26). In calves about 90 per cent of rotavirus isolates belong to one serotype represented by bovine rotavirus (BI~V) UK (33,35).…”

SummaryBovine rotavirus (BRV) V 1005 was characterized by two-way crossneutralization tests as a second serotype of BRV. Virions and inner shell particles of 65 nm and 55 nm diameter respectively, and empty capsids of 65 nm and 55 nm diameter were separated by density gradient centrifugation. Three polypeptides of molecular weight 60,000, 36,000 and 28,000 (minor protein) could be identified in the outer shell of virions and in the larger empty capsids. Inner shell particles contained three polypeptides of molecular weight 105,000, 83,000 and 43,000. Both sizes of empty eapsids showed two polypeptides of molecular weight 75,000 and 55,000 not found in virions. Pulse-labelling of infected cells revealed eight major and three minor intracellular viral polypeptides. Viral polypeptide synthesis started at about 6 hours p.i. and correlated in time with double-stranded RNA synthesis. As soon as viral polypeptide synthesis was detectable, newly synthesized virM polypeptides were incorporated into intracellular viral partieles. Radioactive viral polypeptides appeared without a longer lag period in extraeellular viruses from 6 hours p.i. onwards.
