title: Arrays of hemispheric surface projections on Chlamydia psittaci and Chlamydia trachomatis observed by scanning electron microscopy.
abstract: Scanning microscopy of two strains of Chlamydia psittaci and four strains of Chlamydia trachomatis representative of the wide diversity in origin and behavior of members of the genus revealed patches of regular arrays of hemispheric projections on the surfaces of elementary bodies of all six strains. These distinctive and perhaps unique surface structure are probably present in all populations of chlamydiae.
