This study focuses the role ofmucus fluid to protect fish in contaminated environment. The mucus and fluids from thetypes of Salmo, Cyprinus and Leuciscus fish in Sivas, Ulas Karacalar Lake Dam, DamLake Almus taken and extracted by using 3 different solvent (dimethyl sulfoxide,ethanol and chloroform). In mucus, antibacterial and antifungal properties of theobtained extracts were investigated. Samples are tested on 11 to 19 differentmicroorganisms, including bacteria and fungi. In this study gram-positive bacteria(Staphylococcus aureus, Bacillus subtilis, Bacillus cereus), gram-negative bacteria(Escherrischia coli, Pseudomonas aureginosa, Klebsiella Pneumonia, Enterobacteraerogenes, Salmonella enteritidis, Salmonella gallinarum, Enterococcus Ie calis,Proteus vulgaris) and funguses (Aspergillus jlavus, Aspergillus lumigatus, T roseum,Penicillium brevi-com pactum, Alternaria alternata, Candida utilis, Penicilliumpurpurogenum, Aspergillus niger) are tested in terms of their biological activity throughDisk Diffusion Method, MIC and MBC. Based on obtained findings, when we comparewith inhibition zones formed by antibiotic, it is possible to say that the closest andremarkable effect is on Proteus vulgaris in mucus extracts (Gentamicin 24 mm, SCF 21mm, Azithromycin 13 mm, Neomycin 15 mm). The findings show bacteria and fungiwere not able to generate a significant way zone when mucus from fish extracts in twodifferent regions and three different types are considered. Therefore it is concluded thatmucus extracts do not show any biological activity.Key words: Fish, Mucus, Antimicrobial activity, Fresh water 80 |
