| Abstract | ||
| total of 250 samples of freshwater fishes (130 Carassius auratus and 120 Liza abu) were collected seasonally from October, 2011 to August, 2012 from two regions {Garmat Ali (Kharatrad river) and Harrier (west of Hor Al-Hammar marsh)}. The isolated and characterized bacteria in the study fishes included Staphylococcus aureus, Streptococcus sp., Flavobacterium sp., Aeromonas sp., A. hydrophila, Pseudomonas sp., Yersinia sp., Corynebacterium sp. The aim of present study is test of the pathogenic isolates susceptibility against [Cephalothin (KF), Tetracyclin (TE), Gentamycin (CN), Neomycin (N), Chloramphenicol (C), Streptomycin (S), Nalidixic acid (NA), Erythromycin (E), Oxytetracyclin (OT), Ampicillin (AM)] to know the most antibiotic activity. The oxytetracyclin (OT) (70.45%) had the highest effect on all pathogenic bacteria with a significant difference from that of other antibiotics on pathogenic bacteria. The exception was in the effect of chloramphenicol (C) (66.56%) and streptomycin (S) (65.52%) with no significant difference. Whereas, the neomycin (N) had the lowest effect on all pathogenic bacteria.The Flavobacterium sp. (50%) was the most sensitive pathogenic bacteria to all antibiotics with a significant difference from that of other pathogenic bacteria. The exception was in the sensitivity of Streptococcus sp. (47.88%), and S. aureus (47.17%) with no significant difference. While, the Aeromonas sp. (28.89%) was the most resistant pathogenic bacteria to all antibiotics. | ||
