在实验室检查肠道细菌的实际工作中,往往要在某些非致病菌菌株的鉴定,尤其是在特徵上类似的痢疾菌和伤寒菌的鉴定方面遇到一些困难。就是分解某些碳水化合物培养基(糖培养基)以确定其性质,也仍不能决定此类肠系菌的性属问题,而往往仅待凝集反应发生后,才能真正地阐明它们的本质。因此,鉴定类似的细菌时,是要耗费很多时间和培养基的。某些研究家们已经确定了,变形杆菌属(包括
In the actual work of laboratory examination of intestinal bacteria, it is often necessary to identify some non-pathogenic strains, especially in the identification of similar characteristics of dysentery and Salmonella typhi. Decomposition of certain carbohydrate media (sugar media) to determine its nature, still can not determine the sexual problems of such gut bacteria, and often only after the agglutination reaction occurs, can we really clarify their nature. Therefore, when identifying similar bacteria, it takes a lot of time and culture medium. Some researchers have already determined that Proteus (including
