Serotypes of bovine rotaviruses distinguished by serum neutralization.
Fourteen cytopathic bovine rotaviruses isolated from naturally affected calves were characterized serologically by serum neutralization. Antisera were prepared in guinea pigs against the three isolates and the Lincoln strain of bovine rotavirus. These four rotaviruses were segregated into at least two distinct serotypes (designated types 1 and 2) by serum neutralization. The remaining 11 isolat...
متن کاملAntigenic relationships among some bovine rotaviruses: serum neutralization and cross-protection in gnotobiotic calves.
A method was further developed to screen non-tissue-culture-adapted bovine rotaviruses for serotype, using a neutralization test with infectious fecal rotavirus. One of those rotaviruses (B223) which was not blocked by antiserum to the neonatal calf diarrhea virus (NCDV) serotype was then adapted to cell culture in the presence of the antiserum for two or more passages and hyperimmune antiserum...
متن کاملMolecular and antigenic analyses of serotypes 8 and 10 of bovine rotaviruses in Thailand.
Antigenic and genomic properties of non-serotype 6 bovine rotaviruses isolated in Thailand and Japan were studied by cross-neutralization tests, nucleotide sequence determination of the VP7 gene, and RNA-RNA hybridization. Two Thai strains (61A and A44) were serologically related to a Japanese isolate KK3 which has been assigned to serotype 10. In contrast, strain A5 was found to be antigenical...
متن کاملIdentification of bovine herpesvirus-1 polypeptides involved in serum neutralization.
Bovine herpesvirus (infectious bovine rhinotracheitis virus)-infected cell antigens were solubilized with Nonidet P-40. The crude antigen extract was separated by reaction with bovine hyperimmune serum in line immunoelectrophoresis; individual immunoprecipitates were used to immunize rabbits. Rabbit sera possessing serum neutralizing activity were analyzed by reaction with crude antigen extract...
متن کاملResponse of mice to rotaviruses of bovine or primate origin assessed by radioimmunoassay, radioimmunoprecipitation, and plaque reduction neutralization.
Sera from (i) gnotobiotic BALB/c, CD-1, and CFW mice and (ii) conventional BALB/c mice were evaluated by radioimmunoassay, radioimmunoprecipitation, and plaque reduction neutralization, using the Wa, SA-11, and WC-3 (bovine) strains of rotavirus as the detecting antigens. The gnotobiotic mice had no antirotavirus antibody detectable by radioimmunoprecipitation and no neutralizing antibody at a ...
