ABSTRACT
Real-time amplificationtechniques are currently used to determine the viral nucleic acid (NA) in clinical samples for diagnostic purposes. In disease management contexts, until now, a little have been described for the molecular detection of camel pox virus (CPV). This study reports the development of a Real-time polymerase chain reaction (RT-PCR) for detection of CPV using SYBR green I chemistry. A total of 15 specimens from camels suspected of being infected with CPV were collected from Riyadh Province during 2009 and submitted for virological investigation at the Central Veterinary Diagnostic Lab. (CVDL), Riyadh, Ministry of Agriculture; KSA. In solution; detection and identification of CPV was achieved in 10 samples by conventional polymerase chain reaction (PCR). During further studies performed, it was shown that CPV was isolated in Chorio-allantoic membranes (CAMs) and in Vero cell as well as demonstration of pock lesions and cytopathic effect (CPE) due to CPV were observed while CPV virus antigen was detected and identified by indirect immune-fluorescent assay (IFAT) in Vero cells. A trial for development of a simple and rapid qualitative Real-time polymerase chain reaction (RT-PCR) was applied using primer site belongs to Capripowirus to detect CPV load in prepared tissue samples comparing to inoculated
