Supplementary Studies on the Pathogenic Esherichia Coli (O-28a. 28c: B₁₈) Isolated from the Patients Suffering

Abstract

A pathogenic E. coli strain, Horie strain (O-28a. 28c: B₁₈) isolated from an Ekiri patient was reported by the author et al in Vol.31, 1957 of this journal. Meanwhille, 3 cases with dysenterylike symptoms caused by this agent were experienced by us. These 3 strains demonstrated identical biological properties with the Horie strain and differed a little from the Katwijk. The Horie strain possessed serologically common antigens with 0-28 and 0-42 and on the other hand an antigen specific to the strain.
