title: [Identification of serological group 0128:K67 Escherichia].
abstract: The authors present the results of studies of etiology of acute group intestinal diseases in neonates from whom escherichia of serological group 0128ac:K67 possessing the following characteristics were isolated: of the same (with the H12 antigen) serological and enzymatic type (nonfermenting sucrose and raffinose, fermenting dulcit and sorbit the first 24 hours, and slowly fermenting ramnose). All the cultures isolated were resistant to the majority of antibiotics used at present, and were only weakly sensitive to erythromycin. Difficulties (agglutination of live cultures with production sera in the absence of low agglutinability of heated cultures) in serological typing of the cultures were due to different partial O-antigen composition of the cultures isolated and of the production strain used in the preparation of commercial sera of the given serological group (0128ab:K67). Because circulation of escherichia of serological 0128ac variant was revealed in the USSR there occurred a necessity of their identification in practical laboratories; for this purpose organization of industrial production of the corresponding serum is necessary.
