Evidence for serotypic variation among bovine rotaviruses.
TLDR
Eight field strains of calf rotavirus from the U.K. were compared by neutralisation tests, using convalescent and hyperimmune antisera, suggesting the existence of other potential serotypes in the calf population.Abstract:
Eight field strains of calf rotavirus from the U.K. were compared by neutralisation tests, using convalescent and hyperimmune antisera. Seven of these strains cross-reacted and were considered to be of one serotype, while the 8th was distinguished by a greater than 20-fold two-way difference in neutralisation titre suggesting a second serotype. Three widely-distributed reference strains (U.K., Northern Ireland and Lincoln) cross-reacted with the strains in the dominant serotype, as did 33 of 42 other field calf rotavirus strains. Nine field strains failed to cross-react with either serotype, suggesting the existence of other potential serotypes in the calf population.read more

Some infectious causes of diarrhea in young farm animals.
TL;DR: This review discusses E. coli, rotavirus, and C. parvum as they relate to enteric disease in calves, lambs, and pigs as well as other microorganisms frequently incriminated as causative agents in diarrheas among neonatal food animals.

TL;DR: Bovine rotaviruses from the United Kingdom, Federal Republic of Germany, and Japan that had been shown previously to be distinct from serotype 6 were compared in neutralization tests with B223, and these viruses proved to be a closely reacting group distinct from all other rotavirus serotypes, justifying the establishment of serotype 10 as the second major type of bovinerotavirus.
Journal ArticleDOI
Isolation and characterization of two distinct human rotavirus strains with G6 specificity.
TL;DR: Two new human rotavirus strains, PA151 and PA169, with subgroup I specificity and a long RNA pattern, yet with a serotype G (VP7) specificity different from those of any of the six well-established HRV serotypes are taken into consideration when deciding strategies for the development of an effective RV vaccine.
Journal ArticleDOI
Comparison of atypical rotaviruses from calves, piglets, lambs and man.
TL;DR: Findings are consistent with the hypothesis that rotaviruses belong to at least four separate groups definable by serology and electrophoretype, and the atypical chicken rotavirus may form a fourth distinct group.
Journal ArticleDOI
Bovine rotavirus serotypes and their significance for immunization
TL;DR: Results were interpreted to indicate that cows will respond heterotypically after monovalent vaccination to all rotav virus serotypes with which they have had experience and, therefore, that single serotype vaccination may be sufficient for rotavirus immunization procedures.

Cleavage of Structural Proteins during the Assembly of the Head of Bacteriophage T4
TL;DR: Using an improved method of gel electrophoresis, many hitherto unknown proteins have been found in bacteriophage T4 and some of these have been identified with specific gene products.

Cleavage of structural proteins during the assemble of the head of bacterio-phage T4
TL;DR: Using an improved method of gel electrophoresis, many hitherto unknown proteins have been found in bacteriophage T4 and some of these have been identified with specific gene products as mentioned in this paper.

Rapid diagnosis of rotavirus infection by direct detection of viral nucleic acid in silver-stained polyacrylamide gels.
TL;DR: A rapid simple technique based on the sensitive detection of rotavirus double-stranded RNA genome segments separated in polyacrylamide gels, which is comparable with that of electron microscopy or enzyme-linked immunosorbent assay.

TL;DR: Using the subgroup monoclones, it is determined that some animal as well as human rotavirus strains carry subgroup 2 specificity and that epizootic diarrhea of infant mice virus and turkeyRotavirus are antigenically distinct from other mammalian rotav virus strains.

TL;DR: In a study conducted at Plum Island Animal Disease Center, antiserum against the three combined agents did not specifically neutralize any serotype of swine vesicular exanthema virus.
