RESUMEN
Water extracts of Escherichia coli "O" and "K" antigen test strains (EPEC, ETEC, EIEC, UPEC) were examined in immunodiffusion and immunoelectrophoresis tests. The precipitation arcs corresponding to the O-antigen specificity and to the thermostable polysaccharide K antigen were easy to identify. All strains gave an O antigen precipitation arc found either on the anodic or the cathodic side of application basin and close to this. The so-called enteropathogenic types (from infantile diarrhoea) had a cathodic O antigen arc type; from dysentery-like disease had a negatively charged O-antigen, but no special thermostable K-antigen. Thus E. coli strains which may invade the tissues when conditions allow have a negatively charged surface antigen, either O-antigen lipopolysaccharide or both. Acidic components were found in the anodic O-antigen.

S. haardt and S. ahuza have been isolated first time from the feces and the urine cultures of the patients in Turkey. S. ahuza has been previously isolated from Citellus citellus gelengius in Turkey.

The agglutinating sera against Hanseniaspora osmophila. H. uvarum and H. valbyensis agglutinated the homologous and heterologous Hanseiaspora strains. Cross agglutination and absorption tests showed that there was a common antigenic factor (s) among these three Hanseniaspora species. On the other hand, the tests have shown that the antigenic structures of H. uvarum and H. valbyensis are so much alike that they seem almost identical.
