Physicochemical surface properties of nonencapsulated and encapsulated coagulase-negative staphylococci.

Cell surfaces of three nonencapsulated and three encapsulated coagulase-negative staphylococci were characterized by their surface free energies, zeta potentials, and elemental and molecular compositions. Surface free energies were calculated from contact angle measurements with various liquids. All six strains showed a high surface free energy (103 to 126 mJ.m-2), estimated from the concept of...

Adhesion of coagulase-negative staphylococci to methacrylate polymers and copolymers.

Adhesion of coagulase-negative staphylococci (CNS) was studied onto a homologous series of methacrylate polymers and copolymers. The materials varied in wettability (contact angles) and were either positively or negatively charged (zeta-potential). Bacterial adhesion experiments performed in a parallel-plate perfusion system showed that positively charged TMAEMA-Cl copolymers significantly prom...

Biotyping coagulase-negative staphylococci.

The biochemical profiles obtained with Staph-Ident (Analytab Products, Plainview, N.Y.) panels were combined with the results of adherence and synergistic hemolysis tests to define biotypes among 1,064 clinical isolates representing eight species of coagulase-negative staphylococci. The 672 isolates of Staphylococcus epidermidis were aligned in 69 of 144 potential biotypes in our scheme because...

Coagulase-negative staphylococci.

The definition of the heterogeneous group of coagulase-negative staphylococci (CoNS) is still based on diagnostic procedures that fulfill the clinical need to differentiate between Staphylococcus aureus and those staphylococci classified historically as being less or nonpathogenic. Due to patient- and procedure-related changes, CoNS now represent one of the major nosocomial pathogens, with S. e...

Encapsulation, slime production and surface hydrophobicity of coagulase-negative staphylococci

Infections associated with prosthetic implants or medical devices are most commonly caused by coagulase-negative staphylococci (CNS) [1]. The ability of CNS to produce slime has been suggested to play a critical role in the adhesion onto surfaces of implants and medical devices [2] and in the course of medical device-associated infections [3]. Staphylococcus aureus, the pathogenic counterpart o...
