Experimental pathogenicity of Aphanoascus spp.
Immunodepressed mice were inoculated intraperitonealy with a suspension of conidia and micelia macerate of four species of Aphanoascus (A. keratinophilus, A. fulvescens, A. reticulisporus and A. verrucosus). All produced nodular lesions in the peritoneal cavity, especially in the liver, spleen, diaphragm and peritoneum. The recovery rate of the fungi on phytone-yeast extract agar after one month varied approximately from 20 to 80% depending on the organs. Sections of these revealed the presence of ascospores and hyphal fragments though only in the centre of the nodules. Fungal elements were not detected in organs which were apparently not affected, nor intravascularly.
