The aim of this study is describe the case of ulcer and hemorrhaging (red-sore disease) in a common carp (C. carpio) that is cultivated in floating cages at Al-Hilla river and to finding efficient antibiotic treatments. A total of 144 specimens of the common carp were examined for ulcer with hemorrhaging during the period from December 2017 till the end of November 2018. In this study, red-sore disease was found in 45 specimens. This disease is caused by the infection of Motile Aeromonas Septicemia (MAS). Aeromonas hydrophila, A. sobria and A. veronii were isolated from the skin, gills and intestine of common carp. Aeromonas species were identified with a different percentage in common carp as the follows: A. hydrophila (58.76%), A. sobria (31.83%) and A. veronii (43.3%). Antibiotic susceptibility test of 12 antibiotics (Piperacillin/ Tazobactan, Amikacin, Cefazolin, Gentamicin, Cefoxitin, Ciprofloxacin, Ceftazidime, Levofloxacin, Cefepime, Tigecycline, Imipenem and Trimethoprim/ Sulfamethoxazoleby) showed variable resistances for Aeromonas species. Aeromonas species were identified and examined for antibiotic susceptibility using the VITEK 2 system.
