Heat-induced macroconidia germination in Microsporum gypseum.
A method for obtaining purified ungerminated macroconidia is described, and a technique for obtaining 85 to 90% germination of macroconidia under normal nutritional conditions is presented.
متن کاملRegulation and self-inhibition of Microsporum gypseum Macroconidia germination.
Germination of Microsporum gypseum macroconidia was accompanied by the release of alkaline protease, calcium ions, and inorganic phosphate into the germination fluid. The rate of germination was greatest during the first 2 hr, decreasing thereafter. This decrease in rate was accompanied by a decrease in protease activity, which was caused by an interaction of the enzyme with the inorganic phosp...
متن کاملRelationship of nuclear segregation and macroconidial germination in Microsporum gypseum.
Microsporum gypseum macroconidia germinated at 37 C possessed from one to eight nuclei per germinated spore compartment. The distribution of nuclei per spore compartment was the result of a random packaging of nuclei from the available nuclear population. Partial inhibition of germination by incubation at 25 C or at 37 C in the presence of 10(-4)m phenyl methyl sulfonyl-fluoride resulted in an ...
متن کاملDermatophytosis, Microsporum canis, Trichophyton mentagrophytes, Microsporum gypseum
Overview: The fungal skin disease dermatophytosis has come to be called ringworm because of the appearance of the skin lesion that characteristically occurs with this disorder: a circular area of hair loss with a red, raised outer rim. These lesions result from an inflammatory reaction to the fungus. Most often, dogs and cats are infected by the Microsporum canis fungus, but other types of fung...
متن کاملChanges in Microsporum gypseum mycelial wall and spore coat glycoproteins during sporulation and spore germination.
Ethylenediamine-soluble glycoproteins were extracted from isolated Microsporum gypseum hyphal walls during sporulation and from spore coats before and after germination. This study was carried out to identify a sporulation-specific cell wall protein that possibly served as a substrate for the alkaline protease which initiated the macroconidial germination of this fungus. Analyses revealed that ...
