Virulence assay of Coccidioides immitis in embryonated eggs.
During work on Coccidioides immitis the need arose for a relatively rapid method for the determination of the virulence of a number of strains of this microorganism. A satisfactory method has been described by Friedman, Smith, and Gordon (1955) in which a standard dose, usually 100 arthrospores, is inoculated intraperitoneally into mice. The virulence was determined from (i) the percentage of a...
متن کاملPolysaccharide of Coccidioides immitis.
Pappagianis, D. (University of California, Berkeley), E. W. Putman, and G. S. Kobayashi. Polysaccharide of Coccidioides immitis. J. Bacteriol. 82:714-723. 1961.-Soluble polysaccharide from mycelia or culture filtrates of Coccidioides immitis was found to consist mainly of mannose, but also included small quantities of galactose and another reducing sugar. Isolation of the polysaccharide by etha...
متن کاملCollagenolytic activity of Coccidioides immitis.
Coccidioides immitis appears to be unable to digest particulate collagen when cultured on collagen-containing semisolid culture media. However, all C. immitis strains solubilized collagen when the fungus was grown in liquid suspension cultures. Moreover, sterile culture filtrates were collagenolytic in collagen-buffer-agar plate assays.

Converse, J. L. (U. S. Army Chemical Corps, Fort Detrick, Frederick, Md.), E. P. Lowe, M. W. Castleberry, G. P. Blundell, and A. R. Besemer. Pathogenesis of Coccidioides immitis in monkeys. J. Bacteriol. 83:871-878. 1962.-Respiratory exposure to arthrospores from the submerged growth of Coccidioides immitis, strain Cash, in liquid medium resulted in similar pathogenesis in monkeys to that of st...
متن کاملMisleading manifestations of Coccidioides immitis in vivo.
We describe a case of coccidioidomycosis in which several unusual morphologic forms of Coccidioides immitis occurred in biopsy tissue from the right lower lung of a patient. To our knowledge, this is the first case where so many diverse morphologic forms were manifested in a single patient in the absence of typical endosporulating spherules. Immature spherules demonstrating segmentation mimicke...
