Poultrymen are becoming extremely conscious of any disease which results in a decrease in production. Some of these diseases are the result of new intensive methods of management which place considerable stress on the individual bird. Probably the most important fungal diseases of poultry are aspergillosis, favus and moniliasis. Aspergillosis, an infection of the respiratory tract, is generally thought to be caused by Aspergillis fumigatus Frensius. Favus, a chronic dermatomyoosis (dermatomycosis?) is caused by Achorian gallimae. Moniliasis an infection of the mucous membrane lining the upper digestive tract is associated with Candida albicans and other members of the genus Candida. Of these three zyootic (mycotic) infections, only moniliasis has been more than occasionally implicated in disease of epidemic proportions. Moniliasis is generally thought to be associated with unsanitary conditions and possibly secondary to certain debilitating factors. It is also assumed that that Candida albicans organism present as a commensal or parasite in some intestinal tracts, may serve as a reservoir of infection. It was the purpose of this study to determine the effects of certain antibiotics in the form of feed supplements on this intestinal parasite, and to learn something of the cultural characteristics of this yeastlike fungus.
