The caliciviruses were included in Picornaviridae family, and only in 1979 they were classified as Caliciviridae members. There are four genera included in this family: Vesivirus, Lagovirus, Norovirus and Sapovirus. Its genome consists of a single-stranded poly-adenylated RNA molecule with positive polarity. The Vesivirus genus includes viruses that cause vesicular disease in feline (FCV), swine (VESV) and cetacean and piniped (SMSV). Lagoviruses include the European brown hare syndrome virus (EBHSV) and Rabbit hemorrhagic disease virus (RHDV) which infects hare and rabbits causing hepatic disease. The noroviruses, previously named, Norwalk-like virus, are the main cause of nonbacterial human gastroenteritis in some European countries, United States and Japan. The natural hosts of this virus are the man, bovine, swine, and rats. Sapovirus infects human and swine, especially the young. In human the infection is normally a mild diarrhea. In swine it has been described intestinal villous atrophy and diarrhea in experimental infected piglets. Despite the high genetic variability of sapoviruses, recombination between strains from different genogroups or genotypes was already verified, which suggests the zoonotic potential of the disease.
