| further studies on bluetongue and bluetongue-related orbiviruses in the sudan. | the seasonal incidence of bluetongue virus (btv) in central sudan is related primarily to fluctuations in the prevalence of the vector, culicoides imicola. population densities of this midge begin to rise with the onset of precipitation and peak during october, before falling sharply at the end of the rainy season in november. these are also the months of btv transmission. populations of c. schultzei, the commonest midge in central sudan, are also related to the rainy season but this species doe ... | 1990 | 2174372 |
| application of molecular biological techniques for detection of epizootic hemorrhagic disease virus (ehdv-318) recovered from a sentinel calf in central sudan. | epizootic hemorrhagic disease virus (ehdv), isolate 318 (ehdv-318), an untyped virus recovered from a sentinel calf herd at the khartoum university farm in central sudan, was characterized using molecular biological techniques. with dot blot hybridization technique, a cdna probe derived from genome segment 6 of ehdv-2 (alberta strain) hybridized with rna from ehdv-318. application of serogroup-specific ehdv polymerase chain reaction (pcr) to ehdv-318 rna resulted in specific amplification of a 3 ... | 1996 | 8972046 |
| serogrouping and topotyping of sudanese and united states strains of epizootic hemorrhagic disease virus using pcr. | 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 ehd ... | 1997 | 9280388 |
