Microbiological characteristics, presumptive identification, and antibiotic susceptibilities of Staphylococcus lugdunensis.
This study validated abbreviated methods for the presumptive identification of Staphylococcus lugdunensis and studied the antibiotic susceptibilities of 106 isolates. The combination of positive responses to ornithine and pyrrolidonyl arylamidase identified all S. lugdunensis isolates. Resistance to penicillin and methicillin was detected in 27 and 5% of isolates, respectively.
متن کاملIn vitro antimicrobial susceptibilities of penicillinase-producing and non-penicillinase-producing strains of Neisseria gonorrhoeae isolated in Durban, South Africa.
The in vitro susceptibilities of 22 penicillinase-producing and 32 non-penicillinase-producing strains of Neisseria gonorrhoeae to 13 antimicrobial agents, including the new semisynthetic penicillins and cephalosporins, are reported. Ceftriaxone, ceftazidime, and cefotaxime were the most active agents tested; none of them had an MIC of greater than 0.03 micrograms/ml. Amoxycillin plus clavulani...

متن کاملColony variation in Staphylococcus lugdunensis.
Staphylococcus lugdunensis is being increasingly reported as a pathogen with an outcome resembling that of S. aureus rather than coagulase-negative staphylococci. Recent local isolates exhibited colonial variation that delayed identification and interpretation of clinical significance. Until now previous descriptions have not emphasized colonial variation as an important identifying characteris...
متن کاملSevere Staphylococcus lugdunensis keratitis
We report a severe case of Staphylococcus lugdunensis (S. lugdunensis) keratitis presenting as suppurative keratitis in a 77-year-old woman. The patient's chief complaint was eye pain and decreased visual acuity in her right eye. Suppurative keratitis with a severe corneal abscess was diagnosed by a slit-lamp ophthalmic examination. The causative organism was identified as S. lugdunensis by bac...
