Strains of Escherichia coli, isolated during an outbreak of infantile gastroenteritis in one ward were serotyped and tested for incompatibility against each other on semisolid agar. Serotypes commonly isolated in various parts of the world from various habitats showed a greater incompatibility than more rarely isolated serotypes, suggesting that the former may have a selective advantage and be more able to displace other serotypes in a given habitat.
在一个病房爆发婴儿肠胃炎期间分离出的大肠杆菌菌株进行了血清分型，并在半固体琼脂上测试了它们之间的不相容性。在世界不同地区、不同栖息地常见分离出的血清型比较少见分离出的血清型表现出更大的不相容性，这表明前者可能具有选择优势，并且在给定栖息地中更有能力取代其他血清型。
