| trajectory analysis of winds and vesicular stomatitis in north america, 1982-5. | outbreaks of vesicular stomatitis, serotype new jersey, during epidemics in the united states and northern mexico, 1982-5, were examined by backward trajectories of winds to investigate spread and possible sources. the outbreaks selected for analysis did not involve introduction of disease by infected animals. the findings indicate that wind could have been responsible for carrying infection from northern mexico to arizona and new mexico and thence to colorado and utah and on to wyoming, idaho a ... | 1990 | 2157606 |
| genetic variation of bluetongue virus serotype 11 isolated from host (sheep) and vector (culicoides variipennis) at the same site. | genetic relatedness of 2 strains of bluetongue virus (btv) serotype 11 that were isolated from the same geographic site--one from host (sheep) and the other from the vector culicoides variipennis during an enzootic of bluetongue at bruneau, idaho, in august 1973--was determined by comparing the oligonucleotide fingerprint analyses of the individual double-stranded rna segments of the genomes. it was observed that the 2 strains of btv-11 exhibit considerable differences in their genotypes, the pe ... | 1983 | 6307090 |
