Electropherotypes, serotypes, and subgroups of equine rotaviruses isolated in Japan.

Abstract: Electropherotypes (ET), serotypes, and subgroups of equine rotaviruses isolated from foals in Japan were determined. The ETs of 136 isolates from 1981 through to 1991 were divided into six groups: ET-A-ET-F. The ET-A, -B, -C, -D, -E, and -F were present in 3, 1, 121, 9, 1, and 1 strains, respectively. Representative viruses of ET-A, -B, -C, and -D were identified as serotype G3. Viruses of ET-E and -F were identified as serotypes G 10 and G 5, respectively. The four representative viruses of serotype G 3 did not belong to either subgroup I or II. The two viruses of serotypes G 5 and G 10 belonged to subgroup I. Serotype G 3 strains possessing ET-C were prevalent among the foals throughout the study period.

The research article discusses the categorization of various equine rotaviruses found in foals in Japan based on electropherotypes, serotypes, and subgroups. It identifies that the common serotype G3 associated with electropherotypes A to D was predominant throughout the study period.

Research Overview

  • The core aim of this research was to determine the electropherotypes (ET), serotypes, and subgroups of equine rotaviruses isolated from foals in Japan. This categorization was based on the structural difference of these viruses.
  • The classification was carried out over a decade-long period, from 1981 to 1991.

Classification of Viruses

  • Broadly, the 136 rotavirus isolates were divided into six electropherotype groups: ET-A through ET-F.
  • However, these groups were unevenly distributed amongst the isolates. A vast majority of isolates, 121, belonged to ET-C. The remaining ET groups A, B, D, E, and F accounted for 3, 1, 9, 1 and 1 strains, respectively.

Serotype Identification

  • The study identified representative viruses for each electropherotype. It found that representative viruses of ET-A, -B, -C, and -D were all categorized as serotype G3.
  • On the other hand, viruses of the less common ET-E and -F were identified as serotypes G 10 and G 5, respectively.

Subgroup Identification

  • No representative virus of the dominant serotype G3 was found to belong to either subgroup I or II. This suggests a certain distinctiveness of this serotype.
  • Conversely, the two viruses of serotypes G 5 and G 10 were found to belong to subgroup I, indicating a common characteristic.

Prevalence of Serotype G 3

  • Despite the lack of a clear subgroup, the study found serotype G 3 strains possessing ET-C to be prevalent among the foals throughout the study period. This indicates a significant role played by this particular serotype in the rotaviruses affecting the foals in Japan over the observed period.
