ABSTRACT
Fungal species, which were shown to colonize consistently on the skin surface of the breast region of adult (1 year old) white leghorn fowl, were identified as Aspergillus sydowii, A. tamarii, A. rugulosus and Absidia corymbifera. Of these, A. sydowii and A. tamarii were the dominant forms. Two species of fungi, namely, Aspergillus niger and Scopulariopsis brevicaulis were shown to be present in the cultures of the scrubbings from breast skin surface after 60 days of captivity of the fowls. Extirpation of the uropygial gland resulted in encouragement of the in vitro population growth of all species of fungi except that of A. rugulosus. The effect was found to be very conspicuous for A. sydowii and A. tamarii, particularly after 60 days of gland removal. Addition of total lipids and the wax diester component of free-flowing uropygial secretion as 0.2% suspension in Sabouraud's agar medium of individual fungal isolates caused marked suppression of the population growth of A. sydowii, A. tamarii, Absidia corymbifera and to some extent of S. brevicaulis. Other components of secretory lipids, such as wax alcohols (2,3-alkane-diols), wax acids, triglycerides and hydrocarbons (including squalene) when supplemented separately to culture medium of individual fungi at identical concentration, were also shown to cause inhibition of the growth of most of fungal species at different degrees.
