人李斯特菌病由伊氏李斯特菌引起。

Two species of Listeria are pathogenic; L. monocytogenes infects humans and animals, and L. ivanovii has been considered to infect ruminants only. We report L. ivanovii-associated gastroenteritis and bacteremia in a man. This isolate was indistinguishable from prototypic ruminant strains. L. ivanovii is thus an enteric opportunistic human pathogen.

两种李斯特菌属物种具有致病性；单核细胞增生李斯特菌感染人类和动物，而伊氏李斯特菌被认为仅感染反刍动物。我们报告了一例人类伊氏李斯特菌相关性胃肠炎和菌血症。该分离株与典型的反刍动物菌株无法区分。因此，伊氏李斯特菌是一种肠道机会性人类病原体。
