Abstract
The World Organization for Animal Health (OIE) Code chapter on FMD includes camelids as being susceptible species to FMD similar to cattle, sheep, goats and pigs. A total of 376 field camel sera, collected from different regions of Riyadh and AlQassim Province in the Kingdom of Saudi Arabia, were screened for the presence of antibodies produced against 3ABC non® structural proteins (NSP) of FMDV using a commercially available kit , PrioCHECK FMDV NS. Sera that tested positive on NSP were screened for serotype-specific antibodies towards the seven serotypes of FMD virus using liquid phase blocking ELISA. Only 24 out of 376 (6.3%) serum samples were positive for antibodies against NSP. All sera that tested positive on NSP and screened for antibodies against all the seven FMDV serotypes (O, A, C, Asia 1, SAT 1, SAT 2 and SAT 3) were found positive for antibodies against serotype O.

Foot-and-mouth disease (FMD) is a highly contagious disease affecting domestic and wild cloven hooved animals (Artiodactyla)
All sera that tested positive on nonstructural proteins (NSP) and screened for antibodies against all the seven foot and- mouth disease virus (FMDV) serotypes (O, A, C, Asia 1, SAT 1, SAT 2 and SAT 3) were found positive for antibodies against serotype O. This lower seroprevalence of (6.3%) reveals that dromedaries appear as being susceptible to infection with FMDV serotype O, but they are unlikely to play any significant role in the natural epidemiology of FMD
Kumar et al(1983) described isolation of FMDV serotype O from one of two randomly selected dromedaries in India and Moussa et al (1987) in Egypt have described a strain of type O FMD virus was isolated in Giza from a camel with vesicular, ulcerative stomatitis and they suggested that dromedaries are susceptible to natural FMD
Summary
Foot-and-mouth disease (FMD) is a highly contagious disease affecting domestic and wild cloven hooved animals (Artiodactyla). It remains the single most difficult animal viral disease to control and causes severe economic losses to the livestock industry (Alexandersen et al 2003; Alexandersen and Mowat, 2005). Bactrian camels can relatively be infected with FMDV under experimental conditions and develop frank clinical disease (Larska et al 2009), while Several investigations appear to indicate that dromedaries are of low susceptibility to inoculation with FMD virus serotype O but that they do not present a risk in transmitting FMD to susceptible animals (Wernery and Kaaden, 2004; Alexandersen et al 2008). Kumar et al(1983) described isolation of FMDV serotype O from one of two randomly selected dromedaries in India and Moussa et al (1987) in Egypt have described a strain of type O FMD virus was isolated in Giza from a camel with vesicular, ulcerative stomatitis and they suggested that dromedaries are susceptible to natural FMD
