帝企鹅

帝企鹅是世界上体型最大的企鹅，身高可达1.2米，体重达45千克，栖息于南极大陆极端恶劣的环境中。它们在隆冬的黑暗中、零下60°C以下的严寒里繁殖，雄鸟将唯一的蛋置于脚背上，藏于育卵囊下孵化长达65天，而雌鸟则在此期间出海觅食。数千只帝企鹅组成的群体通过循环交换位置、使个体轮流经过温暖的核心区域这一抱团取暖行为，堪称合作生存的典范。

单核细胞增生李斯特菌是革兰阳性运动菌，是李斯特菌病的病原体，对孕妇、新生儿、老年人和免疫功能低下者尤其危险。它是一种兼性胞内寄生菌，存在于土壤、水和多种食品中，能在冷藏温度下生长。与受污染的即食食品（如熟食肉类、软奶酪和生蔬菜）相关的暴发事件频繁发生。
