Serological typing of coagulase-negative staphylococci using monoclonal antibodies

New method for typing coagulase negative staphylococci.

A serological method for distinguishing coagulase-negative staphylococci from micrococci.

Absorbed antisera prepared against heat-killed suspensions of a coagulase-negative staphylococcus and of a micrococcus were used in a slide-agglutination test. A collection of 176 coagulase-negative aerobic cocci, from which Staphylococcus aureus had been excluded, was classified into staphylococci and micrococci by means of the test for anaerobic utilization of glucose. Of 113 staphylococci, 9...

Characterisation and functional aspects of monoclonal antibodies specific for surface proteins of coagulase-negative staphylococci.

Mouse monoclonal antibodies (MAbs) raised against whole cells of Staphylococcus epidermidis strain 354 were characterised morphologically and functionally. Nine MAbs showed strong reactivity with coagulase-negative staphylococci (CNS). Only two MAbs were specific for CNS; both belonged to the IgG1 subclass, and one, MAb 36.4, reacted only with the strain used for immunisation. In immunoblotting...

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...
