[Immunoelectrophoretic analysis of Escherichia coli strains (EPEC, ETEC, EIV and UPEC) (1)]. / Escherichia coli (EPEC-ETEC-EIV ve UPEC) Suslarinin immünoelektroforetik analiz örnekleri (1).

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.

[Salmonella serotypes isolated in Turkey to the end of 1984]. / Türkiye'de 1984 yili sonuna kadar tesbit edilen Salmonella serotipleri.

59 Salmonella serotypes which belong to A, B, C1, C2, C3, D1, E1, E4, F, G1, H, I, M, P, Q and U groups of Kauffmann - White schema were isolated in Turkey until the end of 1984.

[First isolation of Salmonella haardt and Salmonella ahuza serotypes in humans in Turkey]. / Memleketimizde insandan ilk defa tesbit edilen salmonella haardt ve salmonella ahuza serotipleri.

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.

[Salmonella serotypes isolated in Turkey through 1983]. / Türkiye'de 1983 yili sonuna kadar tesbit edilen salmonella serotipleri.

Sixty Salmonella serotypes which belong to A, B, C1, C2, C3, D1, E1, E4, F, G1, H, I, M, P, Q and U groups of Kauffman-White's schema were isolated in Turkey until the end of 1983.

[The antigenic relationships between Hanseniaspora osmophila, H. uvarum and H. valbyensis strains]. / Hanseniaspora osmophila, H. uvarum ve H. valbyensis suslari arasindaki antijenik iliskiler.

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.
