types A and C, which are gram-positive, anaerobic, spore-forming bacteria, can cause necrotic enteritis in birds. Although is considered a commensal organism in the avian intestinal tract, in association with severe stress, other infectious agents, or immunosuppressive conditions, it can cause disease outbreaks. This report describes a disease occurrence of necrotic enteritis caused by in macaws (). Two adult male blue and gold macaws maintained in a zoo exhibit were presented for postmortem examinations after histories of sudden death. Based on the gross examinations and microscopic evaluation of submitted tissue from both birds, the cause of death was determined to be necrotic enteritis. Microbiologic assays followed by polymerase chain reaction analyses identified the isolated strains as type A, indicated by only being positive for the gene that encodes the α-toxin. The birds were maintained in an exhibit in which patrons can interact with the animals within their environment. Thus, organisms, such as this pathogen, may present a danger for other birds because visitors could disperse the bacterium to other parts of the zoo.
A型和C型（细菌）是革兰氏阳性、厌氧、产芽孢的细菌，可导致禽类坏死性肠炎。尽管（该细菌）被认为是禽类肠道中的共生生物，但在严重应激、其他感染因子或免疫抑制条件下，它会引发疾病暴发。本报告描述了金刚鹦鹉（）中由（该细菌）引起的坏死性肠炎疾病发生情况。在动物园展区饲养的两只成年雄性蓝黄金刚鹦鹉在出现突然死亡病史后接受了尸检。根据对两只鸟送检组织的大体检查和显微镜评估，确定死亡原因是坏死性肠炎。微生物检测随后进行的聚合酶链反应分析将分离菌株鉴定为A型，这仅通过编码α毒素的基因呈阳性表明。这些鸟饲养在一个展区内，游客可以在其环境中与动物互动。因此，像这种病原体这样的生物可能对其他鸟类构成危险，因为游客可能会将细菌传播到动物园的其他区域。
