[Examination of selected biological properties for swarm cells in Proteus mirabilis].

Certain biological properties, which generally are thought to play a role in the bacterial pathogenicity, were compared in short rods, swarm cells and penicillin-induced filaments of Proteus mirabilis S1959. Swarm cells of P. mirabilis S1959 weakly adhere to human uroepithelial cells and also do not penetrate L929 line of mouse fibroblasts.

[The influence of temperature on culture of Staphylococcus aureus for cell adhesion to collagen].

The aim of this study was the investigation of adhesion of 88 S. aureus clinical isolates to collagen. The experiments were extended to determine the influence of growth temperature on collagen adhesin-collagen interaction.

The influence of iron occurring in the growth medium of Staphylococcus aureus on the bacterial adhesion to collagen.

The aim of this study was to investigate the influence of iron present in the growth medium of Staphylococcus aureus on the bacterial adhesion to collagen. The experiments were extended to determinate the siderophore production and to examine the S. aureus isolates surface hydrophobicity.

Molecular and chemical characterization of the lipopolysaccharide O-antigen and its role in the virulence of Yersinia enterocolitica serotype O:8.

The Y. enterocolitica O:8(YeO8) O-antigen repeat units consist of five sugar residues: N-acetyl-D-galactosamine (GalNAc), D-galactose (Gal), D-mannose (Man), L-fucose (Fuc), and 6-deoxy-D-gulose (6d-Gul). The nucleotide sequence of the O-antigen gene cluster of the YeO8 strain 8081-c was determined.

[Use of synthetic antigens in studies of antigenic specificity of Proteus mirabilis 027 lipopolysaccharide].

The frequency of occurrence in clinical material of P. mirabilis strains belonging to serogroup 27 shows the need of identification of their antigenic determinant. Earlier examinations established the chemical structure of the O-specific part of P.
