Summary:Naturally occurring diseased sea urchins Strongylocentrotus purpuratus were present at low incidences in the Monterey Bay area, California (USA); they were used to examine the basic characteristics of disease in sea urchins. Bacteriological sampling of lesion material revealed the presence of 14 bacterial strains including Vibrio, Aeromonas, Flavobacterium and Pseudomonas . Experimental lesions induced in the laboratory had similar characteristics and progression of events as those observed during naturally occurring spontaneous infections. Experimental infectivity tests determined that a stress such as injury was necessary for the formation of a characteristic lesion.
