Host-parasite relationships in the yeastlike form of Paracoccidioides brasiliensis strain IVIC Pb9.
نویسندگان
چکیده
The yeastlike form of Paracoccidioides 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 years. This strain regained its alpha-1,3-glucan up to 25% of the total cell wall when grown in vivo. 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.

متن کاملParacoccidioides brasiliensis: conversion of yeastlike forms into mycelia in submerged culture.
Details of the sequential morphological changes occurring during yeastlike to mycelial-form conversion of the dimorphic pathogen Paracoccidioides brasiliensis are described and illustrated by photomicrographs. Conversion of yeastlike to hyphal morphology was initiated by changing the temperature of incubation from 37 to 23 C. Production by the parent yeastlike cells of elongated buds developing...
متن کاملNew method for estimating digestion of Paracoccidioides brasiliensis by phagocytic cells in vitro.
We describe a method by which phagocytosis and digestion of Paracoccidioides brasiliensis yeast cells by polymorphonuclear leukocytes or other phagocytic cells may be estimated. Suspensions of P. brasiliensis in its yeastlike phase were sonicated, counted, and incubated with known numbers of peripheral blood polymorphonuclear leukocytes. At given intervals, cytocentrifuge droplets were stained ...
متن کاملDistinct patterns of yeast cell morphology and host responses induced by representative strains of Paracoccidioides brasiliensis (Pb18) and Paracoccidioides lutzii (Pb01).
Paracoccidioidomycosis (PCM) is a systemic mycosis, widespread in Latin America. PCM is a granulomatous disease characterized by a polymorphism of lesions depending on the pathogen's virulence, the immune status of the host and its genetic susceptibility. The thermodimorphic fungus Paracoccidioides brasiliensis was considered the only etiologic agent of PCM, yet recent works have shown signific...
متن کاملBiochemical Characterization of Paracoccidioides brasiliensis α-1,3-Glucanase Agn1p, and Its Functionality by Heterologous Expression in Schizosaccharomyces pombe
α-1,3-Glucan is present as the outermost layer of the cell wall in the pathogenic yeastlike (Y) form of Paracoccidioides brasiliensis. Based on experimental evidence, this polysaccharide has been proposed as a fungal virulence factor. To degrade α-1,3-glucan and allow remodeling of the cell wall, α-1,3-glucanase is required. Therefore, the study of this enzyme, its encoding gene, and regulatory...
