title: [Culture-enzyme properties, serologic characteristics, enteropathogenicity and enterotoxicity of Escherichia isolated from patients with diarrhea].
abstract: The results obtained from the serological typing of 194 cultures of shigella-like and cholera-like Escherichia and from the study of their enzymatic properties, enteropathogenecity and enterotoxigenicity, carried out on the corresponding animal models, were compared. The strains were found to belong to 33 serovars; most of them were known in the literature as the causative agents of dysentery-like and cholera-like diseases. Shigella-like Escherichia were subdivided into 15, and cholera-like Escherichia into 19 seroenzymovars; each of them (including all strains it comprised) sharply differed from other seroenzymovars and had its own enteropathogenic and enterotoxigenic characteristics. The data thus obtained indicated that the biological properties of enteropathogenic and enterotoxigenic Escherichia were sufficiently stable and showed the possibility of applying the bacteriological method based on the use of agglutinating sera for the diagnosis of not only dysentery-like, but also cholera-like diseases in humans.
