A recent study revealed that migratory birds may be responsible for the global spread of avian rotavirus A (RVA), yet little is known about the types of RVAs they carry. In this study, a genetic analysis of an RVA strain from a gull species showed that all 11 genes were classified as new genotypes, indicating a greater genetic diversity of avian RVAs. This emphasizes the importance of investigating RVA strains in migratory birds, including gulls.
A recent study demonstrated the possibility that migratory birds are responsible for the global spread of avian rotavirus A (RVA). However, little is known about what types of RVAs are retained in migratory birds. In this study, to obtain information on RVA strains in migratory birds, we characterised an RVA strain, Ho374, that was detected in a faecal sample from a gull species (Larus sp.). Genetic analysis revealed that all 11 genes of this strain were classified as new genotypes (G28-P[39]-I21 -R14 C14 M13 A24 N14 T16 E21 H16). This clearly indicates that the genetic diversity of avian RVAs is greater than previously recognised. Our findings highlight the need for investigations of RVA strains retained in migratory birds, including gulls.
