13. Frequency of Isolation of Staphylococcus lugdunensis in Consecutive Urine Cultures and Relationship to Urinary Tract Infection
Recent reports associate Staphylococcus lugdunensis with severe infection in humans. The frequency of this microorganism in urine cultures is unknown. Five hundred isolates of coagulase-negative staphylococci (CoNS) were recovered from 4,652 consecutive urine specimens submitted for culture to the Mayo Clinic Microbiology Laboratory. Thirty-one (6%) of 500 i

14. Frequency of Isolation of Staphylococcus lugdunensis among Staphylococcal Isolates Causing Endocarditis: a 20-Year Experience
Eighty-nine staphylococcal isolates recovered from patients with bacterial endocarditis at the Mayo Clinic from 1980 to 1999 were studied to determine the prevalence of Staphylococcus lugdunensis among clinical isolates of staphylococci causing endocarditis. Four isolates, all from patients with native mitral valve endocarditis, were identified as S. lugdune

15. Staphylococcus lugdunensis Carrying the mecA Gene Causes Catheter-Associated Bloodstream Infection in Premature Neonate
A premature neonate had a catheter-associated bloodstream infection due to Staphylococcus lugdunensis. The MIC of oxacillin for the strain was >256 μg/ml, and the mecA gene of S. lugdunensis was detected by PCR. The infection was resolved after removal of the line and treatment with vancomycin for 2 weeks.

16. Staphylococcus lugdunensis endocarditis.
Staphylococcus lugdunensis is a recently described coagulase-negative species which has been associated with human infections, including infective endocarditis. A case of native valve endocarditis caused by this organism is described. The initial laboratory detection of S. lugdunensis is facilitated by a positive test for ornithine decarboxylase. The identif

17. Comparison of Real-Time PCR and Conventional Biochemical Methods for Identification of Staphylococcus lugdunensis▿
Staphylococcus lugdunensis is an aggressive, virulent member of the coagulase-negative staphylococci (CoNS) that is responsible for severe, rapidly progressive skin and soft tissue infections and native valve endocarditis. To facilitate prompt identification and appropriate therapy, we describe here a rapid and robust multiplex real-time PCR assay that is ab

18. Staphylococcus lugdunensis.
A fatal case of penicillin resistant Staphylococcus lugdunensis endocarditis on a native valve damaged by rheumatic fever is described. A retrospective examination of 978 tube coagulase negative staphylococcal blood culture isolates was also performed to determine how often this species is isolated. None of the 978 isolates was identified as S lugdunensis. I

19. trans-Complementation of a Staphylococcus aureus agr Mutant by Staphylococcus lugdunensis agr RNAIII
RNAIII from Staphylococcus lugdunensis (RNAIII-sl) in a Staphylococcus aureus agr mutant partially restored the Agr phenotype. A chimeric construct consisting of the 5′ end of RNAIII-sl and the 3′ end of RNAIII from S. aureus restored the Agr phenotype to a greater extent, suggesting the presence of independent regulatory domains.

20. Hemolysins and other characteristics that help differentiate and biotype Staphylococcus lugdunensis and Staphylococcus schleiferi.
Reference strains and clinical isolates representing the newly defined species Staphylococcus lugdunensis and Staphylococcus schleiferi were examined with the battery of tests previously recommended (G.A. Hébert, C.G. Crowder, G.A. Hancock, W.R. Jarvis, and C. Thornsberry, J. Clin. Microbiol. 26:1939-1949, 1988) for other species of coagulase-negative staph

21. Na+/Glutamine (Asparagine) Cotransport by Staphylococcus lugdunensis and Corynebacterium amycolatum
Staphylococcus lugdunensis and Corynebacterium amycolatum each have a Na+/glutamine cotransporter that displays an ordered reaction sequence at the extracellular surface, with sodium binding (Km of 6.5 mM) before glutamine (Km of 50 μM). Asparagine is low-affinity substrate (Km ≈ 1 mM) for each system.

22. Staphylococcus lugdunensis: Report of a Case of Peritonitis and an Easy-To-Perform Screening Strategy
We report on a severe case of peritonitis due to Staphylococcus lugdunensis. The clinical course resembled an infection due to S. aureus more than one due to other coagulase-negative staphylococci. Therefore, we strongly recommend identification and propose an easy-to-perform procedure for screening of this pathogen.

23. Penicillinase production and in vitro susceptibilities of Staphylococcus lugdunensis.
Of 59 clinical isolates of Staphylococcus lugdunensis, 76% were beta-lactamase negative, with penicillin G MICs of less than or equal to 0.13 microgram/ml, and 24% were beta-lactamase positive, with penicillin MICs of greater than or equal to 0.5 microgram/ml. Bimodal distributions were observed also with ampicillin, ampicillin-sulbactam, and amoxicillin-cla

24. Staphylococcus lugdunensis Infections: High Frequency of Inguinal Area Carriage
Following a change in surgical practice, we noted that the rate at which Staphylococcus lugdunensis was isolated from samples from the plastic surgery unit of our hospital increased considerably. We investigated the sources of these S. lugdunensis strains, and we found that in the case of drain colonization or surgical site infection, the strain was more lik
