test and removal procedures vs vaccination for control and eradication of pseudorabies in missouri. | 1979 | 233388 | |
field evaluation of test-and-removal and vaccination as control measures for pseudorabies in missouri swine. | eighteen missouri swine herds were serologically monitored to determine the efficiency of two methods for the control of pseudorabies. a serum neutralization test-and-removal procedure was effective in ten of ten herds using this method. vaccination procedures were less reliable. virus still circulated in five of eight vaccinated herds and a thorough epidemiological evaluation of herd status was impossible. titers caused by vaccination could not be distinguished from those by natural infection. ... | 1982 | 6293689 |
evaluation of field isolates of pseudorabies (aujeszky's disease) virus as determined by restriction endonuclease analysis and hybridization. | sixty-seven isolates of pseudorabies virus (prv) from 13 states were cleaved with 4 restriction endonucleases (re), and after electrophoresis in agarose, their banding patterns were photographed and evaluated. the deoxyribonucleic acid (dna) cleavage fragments were designated into regions specified by molecular weight ranges based on lambda phage dna as a size marker. the 67 prv isolates were evaluated according to the total number of cleavage fragments, by the number of fragments within designa ... | 1984 | 6093637 |
