| antifungal activity of ketoconazole with emphasis on zoophilic fungal pathogens. | the antifungal activity of ketoconazole was studied against fungal pathogens associated with various mycotic infections in animals. a concentration of 10 micrograms of ketoconazole/ml of medium proved fungicidal to trichophyton verrucosum. the same concentration acted as a strong fungistat against the majority of the tested dermatophytes. yeasts were generally more sensitive than yeast-like pathogens. ketoconazole also proved fungicidal against pityrosporon canis and strongly inhibitory on crypt ... | 1986 | 3729122 |

| occurrence of diploid strains of cryptococcus neoformans. | a mating between niacin and pantothenate auxotrophs of cryptococcus neoformans gave a few prototrophic progeny that were self-fertile. these were uninuclear but contained twice as much dna as the parental strains. segregation of nutritional markers was observed upon sporulation. we conclude that these self-fertile strains are diploids. | 1985 | 3882667 |

| treatment of systemic mycoses with ketoconazole: in vitro susceptibilities of clinical isolates of systemic and pathogenic fungi to ketoconazole. | ketoconazole was tested in vitro in three different media against 69 isolates of pathogenic fungi by using a macro-broth dilution procedure. the dimorphic systemic pathogens were highly susceptible, with most isolates of blastomyces dermatitidis and histoplasma capsulatum being inhibited and killed by concentrations less than or equal to 0.39 micrograms of ketoconazole/ml. most isolates of coccidioides immitis were also inhibited or killed by 0.39 micrograms of ketoconazole/ml; however, several ... | 1985 | 3905985 |

| production of diagnostic pigment by phenoloxidase activity of cryptococcus neoformans. | cryptococcus neoformans produces brown pigmented colonies when grown on agar media made from an extract of potatoes and carrots, broad beans (vicia faba), or guizotia abyssinica seeds. since other yeasts do not produce the pigment, these media are useful as differential isolation media for c. neoformans. similar specific pigment was produced by c. neoformans on chemically defined agar media which contained six different substrates of phenoloxidase (o-diphenol: oxygen oxidoreductase ec 1.10.3.1) ... | 1972 | 4118328 |
