Serological Comparison of Type Strains of Porcine, Bovine, and Ovine Mycoplasmas with Atypical Colony Morphology
Serologisk sammenligning af typestammerne for porcine, bovine og ovine mykoplasmer med atypisk kolonimorfologi.
Acta Veterinaria Scandinavica volume 25, pages 29–35 (1984)
Abstract
The type strains of Mycoplasma hyopneumoniae, M. flocculare, M. dispar, and M. ovipneumoniae, all characterized by nipple-less colonies on solid media, were compared serologically. By indirect hemagglutination and by complement fixation tests they were found to constitute a related group. By crossed immunoelectrophoresis a sharing of common antigens was demonstrated, whereas no cross reactivity was noted by the metabolism inhibition test.
The type strains of Mycoplasma hyorhinis and Mycoplasma bovirhinis were included in the study for comparison. Although some cross reaction was noted, they appeared just moderately related to the nipple-less group as well as to each other.
Sammendrag
4 arter af Mycoplasma, nemlig M. hyopneumoniae og M. flocculare fra svin, M. dispar fra kvæg og M. ovipneumoniae fra får er særegne ved ikke at besidde den for mykoplasmer ellers sa karakteristiske spejlægsmorfologi af kolonier på agarplade. Typestammerne for disse 4 arter blev sammenlignet ved forskellige serologiske metoder, og de fandtes at udgøre en antigenmaessigt beslaegtet gruppe i den indirekte haemagglutinationstest og ved komplementbindingsprøven. Forekomst af faelles antigener påvistes ved krydset immunelektroforese, men ved væksthæmningstest i bouillon fandtes ingen krydsreaktion.
Typestammerne for Mycoplasma hyorhinis fra svin og Mycoplasma bovirhinis fra kvaeg blev medtaget i arbejdet for sammenligning. Relativt svage krydsreaktioner kunne pavises mellem disse 2 stammer indbyrdes, og mellem dem og den ovenfor omtalte gruppe.
