WYTWARZANIE ŚLUZU POZAKOMÓRKOWEGO, A ADHEZJA PAŁECZEK ESCHERICHIA COLI DO POLISTYRENU
[EXTRACELLULAR SLIME PRODUCTION AND ADHESION OF ESCHERICHIA COLI STRAINS TO POLYSTYRENE]

Streszczenie.

Oceniono związek pomiędzy adhezją do polistyrenu pałeczek E. coli izolowanych z krwi i z moczu, a ich zdolnością wytwarzania śluzu pozakomórkowego. Szczepy nieadherujące do polistyrenu wytwarzały więcej materiału pozakomórkowego niż szczepy adherujące.

Abstract.

The aim of this study was evaluation of relationship between the ability of extracellular slime production and adhesive properties of E. coli strains. This study included 169 of E. coli strains isolated from urine and blood samples. All of these strains were isolated in the Clinical Microbiology Department of dr. A. Jurasz University Hospital in 2003-2006. After incubation in BHI and TSB medium adherence to polystyrene demonstrated 28 (16,6%) and 20 (11,8%) of E. coli strains, respectively.
Strains incubated in TSB medium demonstrated higher production of extracellular slime than strains
incubated in BHI medium. Non-adhering strains were producing more extracellular slime than adhering
strains both after incubation in BHI as well as TSB medium.
