Abstract |
The present study was conducted to investigate biochemical characteristics and antimicrobial susceptibility of Aeromonas hydrophilia isolated from Jackass penguins (Spheniscus demersus) of zoo and capelins (Mallotus villosus). Seven of Jackass penguins showed anorexia, depression with seriously greenish vomiting for a few days, but resulted in 4 deaths although extensive treatment was carried out by zoo veterinarians. From the 18 samples composed of organs or feces from dead or live Jackass penguins and capelins, 4 (22.2%) Aeromonas hydrophilia were isolated and Bacillus spp, Staphylococcus aureus, Staphylococcus auricularis, Staphylococcus cohnii and Enterobacter aminigenus were also identified. Antimicrobial susceptibility tests of Aeromonas hydrophilia showed that all isolates were susceptible to amikacin, gentamicin, kanamycin, norfloxacin and trimethoprim- sulfadimethoxazole. However, all isolates were resistant to the following antimicrobials; ampicillin, bacitracin, c ephalothin, cefazolin, noboviocin, penicillin and vancomycin. |
