Sapovirus, a member of the family Caliciviridae, is anetiologic agent of gastroenteritis in humans and pigs.Analyses of the complete genome sequences led us toidentify the first sapovirus intergenogroup recombinantstrain. Phylogenetic analysis of the nonstructural region(i.e., genome start to capsid start) grouped this strain intogenogroup II, whereas the structural region (i.e., capsidstart to genome end) grouped this strain into genogroup IV.We found that a recombination event occurred at the poly-merase and capsid junction. This is the first report ofintergenogroup recombination for any calicivirus and high-lights a possible route of zoonoses because sapovirusstrains that infect pig species belong to genogroup III
