Abstract: The whole process of diagnosis, treatment and prognosis for a Yangtze finlessporpoise, Neophocaena phocaenoidesasiaeorientalis, that suffered from acute respiratory disease is recorded in this paper. A sample of nasal swab was taken, incubated in blood-agar plate under aerobic and anaerobic culture conditions at 37℃ and the cultured bacterium was identified. Combining these results with hematology data and blood chemistry of the animal, the pathogen was determined to be Pseudomonas aeruginosa (PA). Treatment was implemented guided by drug-sensitivity tests of PA and prognosis was good. Through summarization of the data of this process, it was learned that:1) It is important to enhance the measures of disinfection in the rearing environment so as to decrease the possibility of acquired PA infection; 2) Daily detection of PA in feces and aspiratory sample is necessary for prevention and control of the disease in the early stage; 3) Timely cure of the disease depends on correct diagnosis, and drug-sensitivity testing is necessary for correct treatment. 4) Behavioral change by the animal is a good indication in both the early and the post-treatment stages of the disease.
