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 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...
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 کاملAntibiotic resistance of coagulase-negative staphylococci and micrococci.
Five hundred and seventy strains of Gram-positive, catalase-positive, coagulasenegative cocci from various sources were classified on the basis of their ability to grow anaerobically and to ferment mannitol. Five groups were distinguished. The frequency of strains classified in the five groups varied with the source. Only 26% of the strains were sensitive to all the nine antibiotics used in the...
