| equine markers genes. polymorphism for group-specific component (gc). | polymorphism of equine gc protein was demonstrated by immunofixation electrophoresis with a goat anti-human gc antibody. three different phenotypes, f, fs and s, were found. family data supported the genetic theory of two autosomal codominant alleles, gcf and gcs. both alleles occurred in standardbred, thoroughbred and arabian horses and in shetland ponies. a frequency of 0.23 for gcs in the american standardbred horse indicates the system should be useful for problems of identification and pare ... | 1978 | 84540 |
| solid phase indirect radioimmunoassays for the rapid diagnosis of sindbis virus antigen. | indirect radioimmunoassays have been developed for the rapid detection of sindbis virus. dilutions of sindbis virus from tissue culture fluids have been immobilized and allowed to react with rabbit anti-sindbis virus antibodies. the bound antibodies were assayed either by 125i-labelled anti-rabbit igg-antibodies or alternatively by addition of human complement and 125i-labelled anti-human c1q antibodies or 125i-labelled protein a. | 1978 | 84855 |
| observations on the m-wave and the cnv in the squirrel monkey. | a typical cnv paradigm, with food as reward, evokes in the squirrel monkey's post-arcuate and post-central cortices both m-waves in response to the cues and what appears to be a cnv in the interstimulus interval. both wave forms appear to be generated locally in cortex and to be more closely related temporally to the cues than to the animal's behavioral response. the cnv, like the m-wave, appears to reflect the animal's level of interest in obtaining the reward. it is smaller when the animal mis ... | 1979 | 85525 |

| identification of haemophilus aphrophilus and actinobacillus actinomycetemcomitans by dna-dna hybridization and genetic transformation. | dna-dna hybridization was used to identify clinical isolates as haemophilus aphrophilus or actinobacillus actinomycetemcomitans. some of the isolates were naturally competent for genetic transformation and were also used as dna recipients for identification of other isolates. the results obtained by hybridization were supported by interstrain-to-intrastrain transformation ratios. distinction between the closely related species h. aphrophilus and a. actinomycetemcomitans was generally clear-cut b ... | 1990 | 2229383 |
| haemophilus aphrophilus isolated from blood. | h. aphrophilus was isolated from 11 successively cultivated blood samples of a male (72) with a fatal atypical endocarditis. identification and differential diagnosis from actinobacillus (haemophilus) actinomycetemcomitans was done on the basis of phenotypic characters of the microorganism. | 1990 | 2248686 |
