Abstract
|
|
|
Background:
@EN Recently, coagulase-negative staphylococci(CNS) have been recognized as an important cause of hospital-acquired infections, including bacteremia. This study was to evaluate the identification methods, antibiotic susceptibility test, and slime
test
of CNS isolated from blood.
@ES Methods:
@EN A total of 21 cases of CNS were isolated from the blood specimens in patients with bacteremia. To evaluate two commercially available rapid methods for identification of CNS species, the API Staph and the Vitek Gram-Positive Identification
Test(GPI)
Card were compared With conventional methods. And the relationship between antibiotic susceptibility test and slime test was investigated.
@ES Results:
@EN Both commercial methods gave a correct identification in 81% of the cases. Antibiotic susceptibility test revealed higher resistance rates, especially for Staphylococcus epidermidis, than those for CNS species isolated from patients admitted
to
our
hospital in 1993, but the result was statistically insignificant, except for clindamycin. 12 out of 14(86%) were methicillin resistant S. apidermidis and 13 isolates of the 14 S. epidermidis produced slime.
@ES Conclusion:
@EN To establish the clinical significance of CNS, the identification
of CNS species using rapid identification systems and the slime test should be performed in addition to antibiotic susceptibility test.
