Terrestrial fungi inhabiting certain species of nile fishes in Egypt

Abstract

Twenty specimens of six species of Nile fishes were examined for the presence of fungi. Of which 2 were from Alestes nurse; 3 from Bagrus docmac; 4 from Barbus bynni; 6 from Chrysichthys auratus; 4 from Lates niloticus and 1 from Malapterurus electricus. Forty-three fungal species in addition to 1 variety appertaining to fifteen genera were recovered from skin (15 genera and 34 species + 1 variety); gills, kidney (12 genera and 30 species + 1 variety, each); liver (11 genera and 30 species + 1 variety) and intestine (13 genera and 30 species + 1 variety) of all specimens, using glucose Czapek-Dox medium at 28°C. The most common genera were Aspergillus, Penicillium and Trichoderma.

20 Exemplare aus 6 Fischarten des Nils wurden auf Pilzvorkommen untersucht. (Fischarten: Alestes nurse, Bagrus docmac, Barbus bynni, Chrysichthys auratus, Lates niloticus, Malapterurus electricus.) Dabei wurden 43 Pilzarten, die 15 Gattungen angehörten, von der Haut, aus den Kiemen, den Nieren, der Leber und dem Darmtrakt isoliert. Hierbei wurde die Isolation mit Glucose Czapek-Dox Medium bei 28°C vorgenommen. Die verbreitetsten Gattungen waren Aspergillus, Penicillium und Trichoderma.
