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...
متن کاملCoagulase-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...
متن کاملVirulence factors of the coagulase-negative staphylococci.
Coagulase-negative staphylococci (CNS) have gained substantial interest as pathogens involved in nosocomial, particularly catheter-related infections. The pathogenic potential of CNS is mainly due to their capacity to form biofilms on indwelling medical devices. In a biofilm, the bacteria are protected against antibiotics and from attacks by the immune system. The factors contributing to biofil...
متن کاملEmergence of teicoplanin-resistant coagulase-negative staphylococci.
Over a period of 5 years we have recovered 32 clinical isolates of coagulase-negative staphylococci (CoNS) exhibiting either decreased levels of susceptibility or true resistance to teicoplanin (MICs, 16 to 128 micrograms/ml); these isolates make up 0.55% of the total CoNS isolated by us. Twenty-nine of the strains were also methicillin resistant, and all were susceptible to vancomycin. Fourtee...
متن کاملImmunoblot fingerprinting of coagulase negative staphylococci.
Coagulase negative staphylococci have become prevalent nosocomial pathogens following the implantation of foreign bodies such as prosthetic valves, cerebrospinal fluid shunts, joint prostheses and central venous catheters. They are also the most common contaminants of blood cultures so that a means of differentiating contamination from a true bacteraemia is important.' Assessment of the clinica...
