Comparative Immunological, Biological and Biophysical Behaviour of Meningopneumonitis Viral Antigenic Preparations

Abstract

THE Psittacosis-LGV-Trachoma (PLT) group of viruses is mainly characterized by their complement-fixing (CF) activity1–5. We have recently reported multi-functional, that is, CF, precipitating and leuco-agglutinating meningo-pneumonitis viral MPV sub-units6. These immunological sub-units differ from those observed by electron microscopy after negative staining. They could easily be obtained by genetron extraction of the virus (FEM)6. We now wish to report immunological, biological and biophysical behaviour of FEM sub-units in comparison with several other antigenic preparations reported in the past.
