Pathogenic. Found in chronic dis- charges from ear. e. Aspergillus repens. Much as (d).. Pig. 72.—Saccharomyces ellipsoides. Very common in fruit products as jams, jellies, etc. Living yeast cells show budding of cells and vacuoles. Dead yeast cells usually occur singly, the vacuoles are wanting and the cell walls are more distinct, generally due to the absorption of coloring substances from the medium in which they occur. f. Aspergillus pictor. Pathogenic. Occurs in Central America, where it causes a mange disease. g. Aspergillus oryzcB. Nonpathogenic. Cultures of this fungus are used in the manufacture of sak^ (Chinese and Japanese rice wine). The fungus growing and feeding upon the steamed rice grains converts the starch into saccharine substances which are then acted upon by the yeast ferment. III. Hyphomycetes. Systematic position of the pathogenic members not well defined. Life history not yet fully worked out. I. Discomyces bovis. (Actinomyces). The so-called ray fungus which causes the condition in cattle known as actinomycosis, a disease which can be transmitted to Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Schneider, Albert, 1863-1928.
