Ultrastructural investigations of the formation ofCandida albicansgerm tubes and septa

Abstract

Germ tubes, blastospores and pseudomycelia of Candida albicans were studied under the electron microscope. Both germ tube and blastospore formation begin with comparable changes in the cell wall of the mother cell. The major part of the germ tube wall consists of the fourth of the five layers forming the C. albicans cell wall. Germ tubes are precursors of mycelia which can ramify. Septa and septal pores can be demonstrated in later phases. Pseudomycelia can be clearly discerned by means of transmission electron microscopy.
