Abstract :

In order to finding perfect antibiotic against bacterial causes of Salmo trutta caspius brood stocks caudal fin rot syndrom ,after isolation and diagnosting two genus bacteria including Aeromonas and Pseudomonas from caudal damaged fin that have been recognized as a serious affair baceria, antibiogram test was performed using six antibiotic disks including Oxytetracyclin(T) 30 µg ,Trimethoprim (TMP) 5µg ,Chloramphenicol (C) 30µg ,Nitrofurazone (NFX) 5µg ,Erythromycin (E) 15µg and Nalidixic acid (NA) 30 µg. The result of antibiogram test showed all Aeromonas samples were sensitive to Trimethoprim, Chloramphenicol and Nitrofurazone and mostly to Nalidixic acid and Chloramphenicol while most of samples were resistance to Erythromycin and Oxytetracycline. Also Pseudomonas samples only were sensitive to Nitrofurazone and they were mostly resistance to Oxytetracycline, Nalidixic acid, Erythromycin, Trimethoprim and Chloramphenicol. It is necessary to say that using antibiotics against bacterial causes of fin rot syndrom seems logical only after removing other primary causes.
