Abstract
In this study an attempt has been made to determine the yeast flora of the human body, the species comprising it, their distribution, and as far as possible their significance, whether simple saprophytes, potential pathogens, or transients picked up from the surroundings. The increasing use of antibiotics and their modifying effects upon human micro-flora have made it important to obtain as much information as possible upon normal florae, particularly those unaffected or even stimulated by the usual antibiotics. Some surveys of yeasts have been made the past, but not in New Zealand. Changes in taxonomy and improved culture methods have made it desirable to repeat the work, and besides this, one or two surveys upon a few populations, without reference to the yeast flora of the area, cannot be considered to have determined, once for all, the normal yeast flora of the human species.
