“…Several other studies on P. boydii have shown fungus strain variation with regard to nutrition and sporulation (3, 9) and antibiotic sensitivity (4,21). Seeliger (25) reported, however, that considerable antigenic similarity exists among isolates, and our studies further confirm this fact (15)(16)(17).…”

The humoral antibody response elicited by experimental infection with Petriellidium boydii and Monosporium apiospermum was studied. The variables of fungus strain, route of inoculation, and concentration of inoculum were examined. Viable spores from three strains of P. boydii and from three strains of M. apiospermum were inoculated intravenously into mice. Serum specimens were tested for antibody by the microtiter indirect hemagglutination assay. At 4 weeks after infection, the percentage of positive specimens among survivortically related either to the incidence of positive specimens or to the magnitude of the humoral response. Mice inoculated by either the subcutaneous or the intramuscular route with viable or killed spores from M. apiospermum 813 developed antibody. The mean antibody titer was greater in those animals receiving viable spores, and the magnitude of the humoral response was dose dependent. Animals inoculated intravenously with comparable inocula of the same strain developed similar levels of antibody. However, cultural studies of infected mice showed chronic infection only after intravenous inoculation. The kidney was the organ most consistently involved.

“…Although considerable research has been done on A. boydii, one can question the value of conclusions made from data accumulated with a single isolate. Wolf et al (38) demonstrated that a single strain of M. apiospermum was autotrophic for its vitamins, whereas Villela and Cury (37) studied a strain of A. boydii which was biotin deficient and unable to grow at 37 C. In other studies involving more than a single isolate of A. boydii or M. apiospermum (4,5,14), considerable difference has been noted among individual strains with respect to growth and sporulation. Assuming that differences might also exist in the virulence of individual isolates, the pathogenic potential of three strains of A. boydii and three strains of M. apiospermum were examined in this study.…”

Allescheria boydii and its imperfect state, Monosporium apiospermum, were studied to determine whether asexual or sexual strains might exhibit different pathogenic potentials for mice. Six different strains of the fungus were inoculated into mice by the intravenous, intracerebral, intraperitoneal, and intranasal routes. Cortisone-treated mice regularly developed infections after inoculation by any of the routes tested. Mice that had not been treated with cortisone were most susceptible to infection by the intravenous route and least susceptible to infection by the intranasal or intraperitoneal route; nevertheless, all animals that did not receive cortisone were considerably more resistant to infection by the fungus than were comparable groups of cortisone-treated animals. Pathogenicity of the fungus appears to be strain dependent and entirely unrelated to its sexual or asexual form. Studies made to determine accurate viable spore counts of the fungus revealed that the highest viable spore count was generally observed using Sabouraud dextrose agar or potato dextrose agar at an incubation temperature of 37 C for a period of 5 days.
