Abstract

ABSTRACT

The range of cellular and colonial morphologies which occurred in a large group of cultures, including recent isolates, from this country or abroad were studied. The strains were grown on BHI plates or in thiogly collate broth under conditions routinely used in a diagnostic laboratory. Stained smears or dark-field preparations from thioglycollate broth showed rods which varied from diphtheroid-like to long filaments. Microcolonies on BHI agar ranged from small and compact to spider-like with the latter predominating. Mature colonies on the same medium had a smooth or rough appearance. Rough colonies were found in two-thirds of the cultures. The smooth colonies were circular, convex and soft in consistency. The rough colonies were more irregular with a granular or a highly convoluted surface, friable to hard and adherent to the medium.
