Abstract
A description of the structure of the Crassostrea virginica pathogen Perkinsus marinus is provided from observations at the light and transmission electron microscope levels of detail and includes cellular multiplication (palintomy) in the host and zoosporulation in estuarine water as well as observations of cells in axenic culture. The description is primarily a review of previously published information; however, new information is provided on development of walled outgrowths from hypnospores derived from fluid thioglycollate medium treatment of infected host tissue. The protoplast within the outgrowths subdivides to yield small unicells which escape into the ambient water, or the protoplast emerges from the tip of the outgrowth and then subdivides into unicells. A taxonomic and phylogenetic reevaluation of the genus Perkinsus is provided.
