exudates and Aspergillosis

The common etiological agents of onychomycosis are dermatophytes, molds and yeasts. A mycological nail investigation of onychomycosis using direct microscopy and culture was conducted by the Mycology Unit, Department of Medical Microbiology, University of Malaya from March 1996 to November 1998. The study involved 878 nail clippings or subungal scrapings from subjects with onychomycosis. On direct microscopy examination, 50% of the specimens were negative for fungal elements. On culture, 373 specimens had no growth; bacteria were isolated from 15 nail specimens. Among the 490 specimens with positive fungal cultures, 177 (36.1%) were dermatophytes, 173 (35.5%) were molds and 130 (26.5%) were Candida. There were 2% (10/490) mixed infections of molds, yeasts and dermatophytes. Trichophyton rubrum (115/177) and Trichophyton mentagrophytes (59/177) were the main dermatophytes isolated. The molds isolated were predominantly Aspergillus niger (61/173), Aspergillus nidulans (30/173), Hendersonula toruloidea (26/173) and Fusarium species (16/173). 96.9% of the Candida species identified were Candida albicans.

Pulmonary aspergilloma is by no means uncommon in Malaysia. The lack of documentation of its occurrence in Malaysia, is mainly due to the lack of clinical awareness, and the absence of facilities for the proper diagnosis of the infection.

Spontaneous fatal aspergillosis occurred in several species of parrots imported from Latin America, Australia, Malaya and Ghana for studies on the control of psittacosis. Over a period of 4 years, 655 parrots were imported for use in these studies. All birds that died during these investigations were necropsied, and the internal organs of 45 were found to have macroscopic lesions suggestive of aspergillosis. Of these 45 suspected cases, 32 were confirmed as aspergillosis by both histopathology and culture, and three others by histopathology alone. There was no evidence that the remaining 10 had this disease. Of the 32 culturally confirmed cases, 13 were found to be caused by Aspergillus fumigatus, 16 by A. oryzae, and three by both fungi. In this series, three sets of circumstances appear to have been associated with the development of fatal aspergillosis. Their capture and transport to the United States, the administration of chlortetracycline used in the control of psittacosis, and the administration of cortisone acetate in an attempt to activate existent latent psittacosis infections. The possible causal relationship of these factors are discussed.
