Abstract
Foot and mouth disease (FMD) sub-clinically
infected animals, are always a threat to
susceptible herds. During Hajj season 2009 (1431
Hijri) the kingdom of Saudi Arabia (KSA) imported
about 204,583 sheep from FMD free areas from
Republic of Georgia through Jeddah Islamic
seaport. The animals were clinically free from FMD
and authorized as not been previously vaccinated.
However, but during the routine laboratory
examination of serum samples using FMD-3ABC ELISA
some sheep consignments exhibited positivness for
FMD anti-bodies. The liquid phase blocking ELISA
(LPBE) was performed as a confirmatory test which
revealed antibodies against FMD serotype O, the
suggesting that animals may be susceptible to FMD
infection from any endemic countries passed
through during overseas transportation. This study
will contribute towards the development of an
appropriate strategy for FMD control, including
the choice of countries of the animal importation,
as well as assist to improve our understanding of
the epidemiology of FMD.
