Ribotyping of coagulase-negative staphylococci with special emphasis on intraspecific typing of Staphylococcus epidermidis

New method for typing coagulase negative staphylococci.

In vitro activities of arylomycin natural-product antibiotics against Staphylococcus epidermidis and other coagulase-negative staphylococci.

The arylomycins are a class of natural-product antibiotics that act via the inhibition of type I signal peptidase (SPase), and we have found in diverse bacteria that their activity is limited by the presence of a resistance-conferring Pro residue in SPase that reduces inhibitor binding. We have also demonstrated that Staphylococcus epidermidis, which lacks this Pro residue, is extremely suscept...

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...

Interaction of coagulase negative staphylococci with lectins.

AIMS To investigate the reaction of 118 blood culture isolates of coagulase negative staphylococci with a panel of seven lectins. METHODS The interactions between the bacterial suspensions and lectins from Arachnis hypogaea (peanut agglutinin), Bauhina purpurea, Solanum tuberosum (potato starch), Triticum vulgaris (wheat germ agglutinin), Wisteria floribunda, Concanavalin ensiformis and Limul...
