Aeromonas hydrophila is a facultative anaerobic gram-negative bacterium regarded as an opportunistic pathogen in animals. A 17-year-old female crab-eating macaque (Macaca fascicularis) died after experiencing anorexia and depression for several days. The carcass was severely emaciated, and the sternum was exposed under subcutaneous lesions in the thorax. Many abnormal pathological lesions were found, including tracheal inflammation, pulmonary inflammatory emphysema, yellowish discoloration of the liver, enlargement of the gall bladder, necrosis of the heart, congested bilateral kidneys, and enlargement of the adrenal glands. The stomach was empty, mucosal ulcerations were found, and the duodenum was congested. Giemsa staining revealed rod-shaped organisms in the whole blood smear and major organs, which were identified as A. hydrophila. The animal had experienced stress, and decreased immune system function possibly contributed to the infection.
嗜水气单胞菌是一种兼性厌氧革兰氏阴性菌，被认为是动物中的机会致病菌。一只 17 岁的雌性食蟹猴（Macaca fascicularis）在经历了数天的食欲不振和抑郁后死亡。尸体严重消瘦，胸骨在胸部皮下病变下暴露。发现了许多异常的病理病变，包括气管炎症、肺炎性肺气肿、肝脏发黄变色、胆囊肿大、心脏坏死、双侧肾脏充血以及肾上腺肿大。胃是空的，发现黏膜溃疡，十二指肠充血。吉姆萨染色显示全血涂片和主要器官中有杆状生物，被鉴定为嗜水气单胞菌。动物经历了应激，免疫系统功能下降可能导致了感染。
