Abstract
The distribution patterns of keratinophilic fungi isolated from Passer domesticus of a coastal (Puri) and an intercoastal (Dhenkanal) district were compared with respect to three parameters, season, age and sex. Irrespective of the parameters, Chrysosporium tropicum and Rollandina hyalinospora showed the highest frequency of occurrence. Their occurrence in the birds was not determined by any ecological or environmental condition in nature. Thus these fungi exhibited their ecological maturity or firm establishment in nature. The maximum fungal distribution occurred during the monsoon season and was minimal in the summer. Juvenile birds were active carriers of the fungi and the male birds harboured the maximum number of fungi. Thus male juvenile birds carried the maximum number of keratinophilic fungi during the monsoon season. The free-living P. domesticus enhances the degree of dispersal of keratinophilic fungi, it being in frequent contact with human artifacts, breeding in settlements and town gardens ‘Eusynanthropic habit’. The fungi so dispersed are called ‘mesoornithochorus’ as their occurrence in birds is determined to a certain degree by avian habits.
