[Diptera of Calliphora genus, potential carriers and spreaders of swine vesicular disease virus].

Swine Vesicular Disease virus ingested by the adult fly Calliphora persists several days in the digestive tract of the insect and is eliminated in feces. The virus ingested by the insect at larval stage has been recovered from the digestive tract and feces of adult flies. Thus, the dissemination of the virus, even in a limited fashion, seems to be possible and attention is chiefly centered on the second process.
