A STUDY OF POPULATION GENETICS IN THE EUROPEAN LOBSTER, HOMARUS GAMMARUS (DECAPODA, NEPHROPIDAE)
By means of an RAPD analysis, the degree of genetic variation in the European lobster, Homarus gammarus, was assessed. We focused our attention on the Helgoland population, which is isolated by its geographical location. By comparison with seven other European lobster populations we demonstrated that the Helgoland lobster is genetically widely separated from other European lobster stocks. However, all populations investigated showed high values of genetic distance, indicating that genetic exchange among European populations of Homarus gammarus may be restricted. The European lobster populations appeared to be isolated by distance since the pattern of genetic relationships reflects their geo…
Overview of the second international workshop to define swine cluster of differentiation (CD) antigens
The aim of the Second International Swine Cluster of Differentiation (CD) Workshop, supported by the Veterinary Immunology Committee (VIC) of the International Union of Immunological Societies (IUIS), was to standardize the assignment of monoclonal antibodies (mAb) reactive with porcine leukocyte differentiation antigens and to define new antibody clusters. At the summary meeting of the workshop in July, 1995, revisions in the existing nomenclature for the Swine CD were approved, so that the rules are now in accord with those for human and ruminant CD. Swine CD numbers will now be given to clusters of mAb to swine orthologues of human CD molecules when homology is proven by (1) suitable tis…
