Encapsulation, slime production and surface hydrophobicity of coagulase-negative staphylococci
Infections associated with prosthetic implants or medical devices are most commonly caused by coagulase-negative staphylococci (CNS) [1]. The ability of CNS to produce slime has been suggested to play a critical role in the adhesion onto surfaces of implants and medical devices [2] and in the course of medical device-associated infections [3]. Staphylococcus aureus, the pathogenic counterpart o...
متن کاملNew method for detecting slime production by coagulase negative staphylococci.
An alternative method for detecting the production of slime by coagulase negative staphylococci was compared with the routinely used Christensen method on 124 isolates of coagulase negative staphylococci from carriage sites, blood cultures, and infected peritoneal dialysis fluids. The alternative method requires the use of a specially prepared solid medium--brain heart infusion broth, supplemen...
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 کاملPathogenicity and virulence of coagulase negative staphylococci in relation to adherence, hydrophobicity, and toxin production in vitro.
AIMS To study the pathogenicity and virulence characteristics of Staphylococcus epidermidis, Staphylococcus haemolyticus, and Staphylococcus sapro-phyticus. METHODS BALB/c mice were challenged intraperitoneally with graded doses of three strains belonging to each species. LD50s were measured for each strain. Haemolysin (alpha- and delta-) and enzyme (DNAase, lipase, and esterase) production i...
