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...
متن کاملBiotyping 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 کاملCharacteristics of coagulase positive and coagulase negative staphylococci in serum-soft agar.
Preliminary experiments revealed that coagulase positive staphylococci could be distinguished culturallv from coagulase negative staphylococci in a soft agar medium containing a small amount of normal human or rabbit plasma. In a medium of suitably low viscosity, staphylococci produce elongated diffuse feathery colonies. When coagulable plasma is incorporated in such a medium, the colonies of c...
متن کاملEffect of borate on the growth of coagulase-positive and coagulase-negative staphylococci.
Of 235 strains of coagulase-positive Staphylococcus aureus studied, 221 or 94% were inhibited by 1.5 x 10(-8)m sodium borate, whereas only 6 of 57 (10.5%) coagulase-negative strains were inhibited by the same borate concentration. Four of the six coagulase-negatives were food poisoning strains and one was a hospital pathogen. Borate sensitivity was found to correlate well with lysozyme and alph...
