Abstract
The yeastlike form of P. brasiliensis strain IVIC Pb9 reduced the amount of .alpha.-1,3-glucan in its cell wall from 45 to 3% when subcultured in vitro for several yr. This strain regained its .alpha.-1,3-glucan up to 25% of the total cell wall when grown in vivo [in hamsters and mice]. A mutant strain of P. brasiliensis Pb9, named IVIC Pb140, reported to have 1,3-mannan instead of .alpha.-glucan in the cell wall, could not be recovered from experimentally infected animals. The existence of some relationship between the presence of .alpha.-1,3-glucan in the cell wall of the yeastlike form and the pathogenicity of this fungus is suggested in this report.This publication has 15 references indexed in Scilit:
