Abstract

The potential use of the recently reported polymerase chain reaction (PCR) protocol for detection of United States epizootic hemorrhagic disease virus (EHDV) serotype 1 (EHDV-1) and serotype 2 (EHDV-2) ribonucleic acid in cell culture and clinical specimens was evaluated for detection of Sudanese EHDV strains. EHDV serotype 5 (EHDV-5) and EHDV, isolate 318 (untyped) designated (EHDV-318), recovered from sentinel calves at the Khartoum University farm (Sudan) were studied. RNA from EHDV-5 and EHDV-318 and a number of EHDV held isolates, propagated in cell cultures, were detected by the described PCR-based assay. The specific 387 bp PCR products were visualized on ethidium-bromide stained agarose gel. Specificity of the PCR products was confirmed by chemiluminescent hybridization with non-radiolabeled internal probe. Amplification product was not detected when the PCR-based assay was applied to RNA from bluetongue virus (BTV) prototypes serotypes 2, 10, 11, 13, 16 and 17; total nucleic acid extracts from uninfected BHK-21 cells. The results of this study indicated that the previously described EHDV-PCR assay could be applied for detection of Sudanese as well as United States strains of EHDV serogroup. In addition, the described EHDV-PCR assay could be used as a supportive diagnostic assay to the current conventional virus isolation procedures used for detection of EHDV infection in susceptible ruminants.
