Approximately five million live ruminants are imported annually into Saudi Arabia. The majority of these animals are imported shortly before the pilgrimage season from Sudan and the Horn of Africa, where foot and mouth disease (FMD) is known to be enzootic. This study was designed to investigate the impact of the importation of these live ruminants on the epizootiology of FMD in Saudi Arabia.

Swine vesicular disease (SVD) is a contagious viral disease of swine. It causes vesicular lesions indistinguishable from those observed of foot-and-mouth disease. Infection with SVD virus (SVDV) can lead to viraemia within 1 day and can produce clinical signs 2 days after a pig has come into contact with infected pigs or a virus-contaminated environment.

A description of the clinical signs, differential diagnosis, epizootiology and laboratory diagnosis of foot-and-mouth disease in ruminants and pigs is given. Clinical signs are most easily recognised in cattle and pigs. Sheep and goats with foot-and-mouth disease do not show distinct clinical signs and can easily be missed.

We report on a lifelong 'carrier' state of non-cytopathic bovine virus diarrhoea virus (BVDV) in an otherwise healthy pig. Three out of 13 pigs of a litter congenitally infected with BVDV survived for more than 3 months. One pig was BVDV seropositive at 1 month, the second seroconverted between 6 and 8 months, and the third remained viraemic and BVDV-immunotolerant until slaughter at 26 months.

Saudi Arabia imports annually more than 6 millions live ruminants for slaughter. The majority of these animals are imported from countries where foot-and-mouth disease (FMD) is enzootic. Serotypes of FMD virus not incorporated in the vaccine currently used in Saudi Arabia (e.
