A laboratory miniature Siberian pig "Minisibs"--a new laboratory animal in USSR is characterized by a very wide immunogenetic polymorphism for all the blood group systems studied, significantly differing in this respect from all the wild and domestic pigs. When "Minisibs" were compared with American, West-German and Japanese miniature pigs in relation to the blood group systems E, F, G and L, the considerable distinction was demonstrated. These immunogenetic peculiarities indicate adequately the complicated phylogenesis of "Minisibs" and the rovel of different European and Asian domestic pig breeds and wild boars in it. "Minisibs" are to be used mainly as a medical and biological model. Besides, they could be of great use in studies of selection and genetics for modelling microevolutionary processes as well as for obtaining monospecific antisera-reagents which detect a wide spectra of erythrocyte and sera antigens. A prerequisite for this is a well studied immunogenetic polymorphism. |
