The occurrence of bacteria as natural occupants of the intestinal flora of poultry is well documented. The incidence and composition of the yeast microflora, however, have received little attention. A study was undertaken with the objective of identifying the predominant yeasts associated with the trachea of chickens, isolated from broilers of a poultry-processing plant. A total of 38 representative yeast isolates were obtained and identified according to conventional methods. Species belonging to genera of Bullera, Candida, Cryptococcus, Debaryomyces, Rhodotorula, Torulaspora, Trichosporon, and Zygosaccharomyces were isolated at various stages of the broiler program.
