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. Bacterial adhesion to collagen was estimated by using immunoenzymatic assay at absorbance of 492 nm and compared with standard curves obtained for 8 different densities of each strain. The amount of collagen adhesin was indicated by colour reaction intensity measured by immunoenzymatic assay. Hydrophobicity of S. aureus strains was measured by aggregation in (NH4)2SO4 test. Almost all S. aureus strains isolated from bone and joint infections adhered to collagen whereas only a part of soft tissue infections isolates showed this feature. The comparison of adhesive properties of S. aureus cells cultured at 21ºC, 37°C and 42°'C did not make it possible to indicate the optimal culture temperature for S. aureus adhesion to collagen. However, the intensive colour reaction of cells cultured at 37°C with anti-collagen adhesin antibodies proves the production of the highest amount of this adhesin under the mentioned conditions. The influence of growth temperature as well as solid and/or liquid medium on the change of S. aureus hydrophobic properties was not observed. The obtained results show that the S- aureus growth temperature can be one of the factors influencing the staphylococci cells adhesion to collagen.

Our Department of General Microbiology created a wide collection of P. penneri isolates and classified most of them into 19 different O-serogroups. This work describes the classification of 12 remaining P. penneri strains. The lipopolysaccharides extracted from P. penneri strains were tested in an enzyme-linked immunosorbent assay (ELISA) with selected O-antisera against Proteus sp. strains. Homologous and cross-reacting systems were checked in: passive immunohemolysis (PIH), inhibition of ELISA and PIH and Western blot procedure. These studies led to the qualification of tested P. penneri strains to five Proteus sp. O-serogroups, thus completing the serological classification of the whole collection.
