Identification of Fungi Causing Cutaneous Infections

The genus Saprolegnia is one of the most important pathogenic aquatic fungi in farmed and wild fish. In this study 100 samples were prepared from 10 fish ponds in Sari Neka and Behshahr. After cultivation purification and macroscopic and microscopic examinations we were able to isolate the fungi Saprolegnia Parasitka Saprolegnia and Aclia. Their prevalence was 48% Parasitica 38% Saprolegnia 36% acacia and 15% other fungi respectively. Their frequencies are 48 Parasitica 38 Saprolegnia 36 Aclias and 15 other fungi respectively. Also in the study of other parameters and their effect on the presence of Saprolegnia it was observed that the ambient temperature of the water was suitable for the growth of this fungus and also the pH and salinity of the water also affected the presence of Saprolegnia.
