Restriction endonuclease analysis of DNA from ruminant Chlamydia psittaci and its relation to mouse virulence.
DNA from 20 pathogenic or non-pathogenic ruminant strains of Chlamydia psittaci was compared by restriction endonuclease analysis. The strains could be easily differentiated according to their invasiveness for mouse, whatever their pathological origin. DNA patterns of invasive strains were similar, whereas those of non-invasive strains were distributed in two groups.
