Summary
In the presence of autologous complement, maximal phagocytosis of Candida albicans blastospores of both a virulent and attenuated strain by human neutrophils in a monolayer assay was achieved after 30 min. The proportion of phagocytes containing intracellular blastospores was 33–36% with an average of 1.5 blastospores per phagocyte. In contrast to the attenuated strain of C. albicans, the virulent strain resisted opsonization by C‐reactive protein (CRP) and of those blastospores ingested, only 8% were killed. These findings support the concept that CRP may play a protective role in candidosis independent of complement. The fate of strains of different virulence may be a result of differences in CRP receptors or killing mechanisms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
