Cellular and Noncellular Recognition of and Reactions to Fungi in Crayfish

According to current literature, the fungi are of minor importance as parasites on vertebrates where bacteria dominate completely. Schäperclaus (1954) in his book on fish diseases lists many more bacterioses than mycoses. In many invertebrate groups, however, the situation is different. Fungi “compete” successfully with bacteria in insects (Steinhaus, 1963) and according to the recent bibliographies on diseases of invertebrates other than insects (Johnson, 1968; Johnson and Chapman, 1969), far more work is listed on fungal than on bacterial parasites of different host groups.
