Abstract

The occurrence and aetiological significance of Aspergillus fumigatus, an opportunistic pathogen, have been studied in 93 animals with various ophthalmological problems. A total of 93 eye swabs collected from 35 mules, 26 dogs, 13 fowl, 11 cattle, five buffaloes and three camels were investigated mycologically for the presence of A fumigatus. The pathogen was isolated in pure and heavy growth from the swabs from two dogs, one bull, one mule and one fowl. The fungus was also demonstrated directly in clinical material by the potassium hydroxide technique. A fumigatus could not be cultured from the buffaloes and camels. All the five cases had been treated with broad spectrum antibiotics and cortisone and two had received traumatic injury to the eyes (one mule and a bull). The organism was not isolated in pure culture from the conjunctival swabs of 22 apparently healthy animals (11 dogs, six mules, three fowl and two cattle). Many other saprophytic fungi were recovered in mixed cultures but were considered to be contaminants. The clinical signs and diagnostic criteria of oculomycosis have been discussed.
