Effect of amphotericin B on capsule and cell size in Cryptococcus neoformans during murine infection

Antimicrob Agents Chemother. 2005 Oct;49(10):4358-61. doi: 10.1128/AAC.49.10.4358-4361.2005.

Abstract

Antifungal drugs can affect the cellular morphology of Cryptococcus neoformans in culture, which alters its interactions with phagocytes. We examined the effects of amphotericin B on C. neoformans during murine infection. The antifungal reduced capsule size and serum polysaccharide, which suggests an additional mechanism for amphotericin B's efficacy in cryptococcosis.
