In this case, the cause of death of black swan was determined by investigating the daily feeding situation of black swan and combining clinical diagnosis, pathological anatomy, PCR detection and other methods. Clinical autopsy results showed that the dead black swan was dehydrated and emaciated with its stomach filled with large amounts of fine sand and black cloth. The main pathological manifestations were peritonitis, air sac inflammation, perihepatic inflammation and necrosis, pericarditis, and dendritic pancreatic hemorrhage. Simultaneously , and were isolated from black swan bodies. The clinical evidence above showed that the swan died of ingesting human fabric, which blocked its stomach and caused a perforation, followed by a secondary bacterial infection. It is the first reported swan death caused because of eating human-cloth waste, suggesting that humans still need to work hard to protect the environment and care for animals.
在这种情况下，通过调查黑天鹅的每日喂食情况，并结合临床诊断、病理解剖、PCR检测等方法，确定了黑天鹅的死因。临床尸检结果显示，死亡的黑天鹅脱水且消瘦，胃内充满大量细沙和黑布。主要病理表现为腹膜炎、气囊炎、肝周炎及坏死、心包炎和胰腺树枝状出血。同时，从黑天鹅体内分离出了[具体物质1]和[具体物质2]。上述临床证据表明，这只天鹅死于吞食人类织物，织物堵塞了其胃部并导致穿孔，随后引发继发性细菌感染。这是首次报道的天鹅因食用人类衣物垃圾而死亡的案例，表明人类仍需努力保护环境和关爱动物。
