چکیده

A majority of cochlear implant infections are caused by Staphylococcus aureus or Pseudomonas aeruginosa. Reported here is a pediatric patient with a cochlear implant infection caused by methicillin-resistant Staphylococcus lugdunensis, a coagulase-negative Staphylococcus that has only recently been determined to be clinically relevant (1988). Unlike other coagulase-negative Staphylococcus, it is more aggressive, carrying a greater potential for tissue destruction. In pediatrics, the organism is uncommon, poorly described, and generally pan-susceptible. Described herein is the presentation and management of this unusual organism in a pediatric setting.

From clinical microbiology to infection pathogenesis: how daring to be different works for Staphylococcus lugdunensis.

Staphylococcus lugdunensis has gained recognition as an atypically virulent pathogen with a unique microbiological and clinical profile. S. lugdunensis is coagulase negative due to the lack of production of secreted coagulase, but a membrane-bound form of the enzyme present in some isolates can result in misidentification of the organism as Staphylococcus aureus in the clinical microbiology lab...

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 identification of such isolates should not c...

Staphylococcus lugdunensis Infections of the Skin and Soft Tissue: A Case Series and Review

INTRODUCTION Staphylococcus lugdunensis (S. lugdunensis) is a coagulase-negative, Gram-positive bacterium that can be isolated as a component of normal skin flora in humans. However, more recently, it has also been documented as a culprit in skin and soft tissue infections. We describe the clinical features of five individuals with S. lugdunensis-associated skin infections. We review the charac...

Prevalence, identification, and antimicrobial susceptibility of Staphylococcus lugdunensis from various clinical specimens in Korea.

Staphylococcus lugdunensis is an unusually virulent coagulase-negative staphylococcus (CoNS) that can cause many types of infection. All culture specimens were collected from patients at Inje University Busan Paik Hospital between October 2005 and March 2006. S. lugdunensis was identified using the phenotypic biochemical tests and 16S rDNA sequencing. Among 358 CoNS, three strains were identifi...

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. lugdunensis.
