Key result
Serological testing of 151 dromedary camels grazing with FMDV-positive ruminants yielded 0% positive results, indicating FMDV was not transmitted to the camels.
Why the study?
The potential role of camels in the epidemiology of foot and mouth disease in Oman required investigation.
Cross-Sectional (n=151)
Dromedary camels do not appear to be infected by or transmit foot and mouth disease virus even when grazing with infected ruminants.
No FMDV transmission to dromedaries detected; supports species barrier hypothesis but leaves open prospective validation in endemic settings.
The potential role of camels in the epidemiology of foot and mouth disease in Oman was investigated. Sera from local dromedaries (n = 151) that graze with animals (cattle and small ruminants) positive for foot and mouth disease virus (FMDV) non-structural protein antibody (NSP-Ab) were tested for the detection of FMDV NSP-Ab. The samples were tested using a commercial competitive enzyme-linked immunosorbent assay (cELISA) , a rapid immunochromatographic assay and a solid-phase cELISA for the detection of antibodies specific to FMDV serotype O. The results from all three assays were negative when tested with dromedary sera. This indicates that FMDV was not transmitted to dromedary camels kept with FMDV NSP-Ab-positive ruminants.

H. et al. (2020) conducted a cross-sectional in Foot and mouth disease virus (FMDV) (n=151). Grazing with FMDV-positive ruminants was evaluated on Detection of FMDV NSP-Ab and antibodies specific to FMDV serotype O. Serological testing of 151 dromedary camels grazing with FMDV-positive ruminants yielded 0% positive results, indicating FMDV was not transmitted to the camels.
