is a toxin-producing facultatively anaerobic gram-positive bacterium. The bacteria are commonly found in the environment and can contaminate food. It can quickly multiply at room temperature with an abundantly present preformed toxin. When ingested, this toxin can cause gastrointestinal illness, which is the commonly known manifestation of the disease. Gastrointestinal syndromes associated with includediarrheal illness without significant upper intestinal symptoms and a predominantly upper GI syndrome with nausea and vomiting without diarrhea. has also been implicated in infections of the eye, respiratory tract, and wounds. The pathogenicity of , whether intestinal or nonintestinal, is intimately associated with the production of tissue-destructive exoenzymes. Among these secreted toxins are hemolysins, phospholipases, and proteases.
是一种产生毒素的兼性厌氧革兰氏阳性细菌。这种细菌在环境中普遍存在，可污染食物。它能在室温下迅速繁殖，并带有大量预先形成的毒素。摄入后，这种毒素可导致胃肠道疾病，这是该疾病常见的表现形式。与之相关的胃肠道综合征包括无明显上消化道症状的腹泻性疾病以及以恶心、呕吐为主且无腹泻的主要上消化道综合征。它还与眼部、呼吸道和伤口感染有关。无论是肠道感染还是非肠道感染，其致病性都与组织破坏性外酶的产生密切相关。这些分泌的毒素包括溶血素、磷脂酶和蛋白酶。
