Cryptococcus neoformans III. Inhibition of Phagocytosis
AUTOR(ES)
Bulmer, G. S.
RESUMO
Isolated nonhydrolyzed cryptococcal polysaccharide is a rather specific potent inhibitor of the phagocytosis of Cryptococcus neoformans by human leukocytes in vitro. When an encapsulated strain of C. neoformans was cultured in the nonencapsulated state, the rate of phagocytosis was three times greater than when the encapsulated form was used. Our theory that capsular material plays a role in the pathogenesis of cryptococcosis requires (i) that C. neoformans exist in soil in a nonencapsulated state and (ii) that human phagocytes be capable of killing the organisms.
