Two bacterial pneumonia cases of bottle-nosed dolphins (Tursiops gillii) were found in Seoul Zoo. Firstly, severe fibrous pleuropneumonia was revealed in a 14-year-old male bottle-nosed dolphin on its necropsy. The clinical signs included anorexia, listing posture, and vertical submerging after the initial signs of low activity and avoiding trainers. White blood cell count increased up to 31.80 × 103/µl. Despite aggressive antibiotics therapy of intramuscular injection and nebulization it died two months later. At early time of illness Staphylococcus aureus and Proteus mirabilis were isolated. Lately Pseudomonas aeruginosa was isolated from the exhaled air culture and direct sample of lung parenchyma on necropsy. Secondly, a 6-year-old male bottle-nosed dolphin with anorexia and tendency to avoid trainers was completely recovered after prompt treatment with antibiotics and NSAIDs for six days prior to diagnosis. The diagnosis was based on history, clinical signs, blood cell count, and mucous culture from blowhole. The count of white blood cell dramatically decreased from 25.36 × 103/µl to 7.28 × 103/ µl after four days of antibiotics therapy. Staphylococcus aureus was isolated from the culture.
