Coagulase negative staphylococci are normal inhabitant of the human skin flora that account for an increasing number of infections, particularly hospital-acquired infections. Staphylococcus lugdunensis has emerged as a most virulent species causing various infections with clinical characteristics close to what clinicians usually observe with Staphylococcus aureus and both bacteria share more than 70% of their genome. Virulence of S. aureus relies on a large repertoire of virulence factors, many of which are encoded on mobile genetic elements...

INTRODUCTION: Wound infections with Vibrio alginolyticus, a Gram-negative bacterium found in all temperate oceans, are rarely reported. However, a rising incidence of wound infections caused by V. alginolyticus requires better knowledge about this infectious agent. CASE PRESENTATION: We report the case of a 14-year-old boy suffering from a wound infection caused by V. alginolyticus and Staphylococcus lugdunensis after stepping on a sea urchin. Despite wound debridement and antibiotic therapy with cefaclor, the lesion did not heal over several weeks...

Bloodstream infections are a leading cause of morbidity and mortality in the United States and are associated with increased health care costs. We evaluated the Portrait Staph ID/R blood culture panel (BCP) multiplex PCR assay (Great Basin Scientific, Salt Lake City, UT) for the rapid and simultaneous identification (ID) of Staphylococcus aureus, Staphylococcus lugdunensis, and Staphylococcus species to the genus level and the detection of the mecA gene directly from a positive blood culture bottle. A total of 765 Bactec bottles demonstrating Gram-positive cocci in singles or clusters were tested during the prospective trial at 3 clinical sites...

Many human skin diseases, such as seborrheic dermatitis, potentially occur due to the over-growth of fungi. It remains a challenge to develop fungicides with a lower risk of generating resistant fungi and non-specifically killing commensal microbes. Our probiotic approaches using a selective fermentation initiator of skin commensal bacteria, fermentation metabolites or their derivatives provide novel therapeutics to rein in the over-growth of fungi. Staphylococcus lugdunensis (S. lugdunensis) bacteria and Candida parapsilosis (C...

Staphylococcus lugdunensis (SL) is a highly pathogenic bacterium compared to other coagulase-negative Staphylococcus spp. (CoNS). However, in Japan, data for this pathogen are sparse, and the current prevalence of SL bacteremia is unknown.A prospective multicenter study across five facilities was performed to investigate the prevalence of SL in blood culture specimens. There were 3,284 patients with positive blood cultures, and 2,478 patients had bacteremia. Among patients with bacteremia, 7 patients (0.28%) had SL bacteremia...

Staphylococcus lugdunensis (S. lugdunensis) is a coagulase negative staphylococcus (CoNS) that can cause destructive infective endocarditis. S. lugdunensis, unlike other CoNS, should be considered to be a pathogen. We report the first case of S. lugdunensis endocarditis causing ventricular septal defect and destruction of the aortic and mitral valves. A 53-year-old male with morbid obesity and COPD presented with intermittent fever and progressive shortness of breath for 2 weeks. Chest examination showed bilateral basal crepitations, and a grade 2 systolic murmur along the right sternal border...

The use of antibiotics in farm management (growing crops and raising animals) has become a major area of concern. Its implications is the consequent emergence of antibiotic resistant bacteria (ARB) and accordingly their access into the human food chain with passage of antibiotic resistance genes (ARG) to the normal human intestinal microbiota and hence to other pathogenic bacteria causative human disease. Therefore, we pursued in this study to unravel the frequency and the quinolone resistance determining region, mecA and cfr genes of methicillin-susceptible Staphylococcus aureus (MSSA), methicillin-resistant S...

Coagulase-negative staphylococci (CoNS) are opportunistic pathogens that particularly cause infections in patients with implanted medical devices. The present research was performed to study the virulence potential of 53 clinical isolates of Staphylococcus capitis, Staphylococcus auricularis, Staphylococcus lugdunensis, Staphylococcus simulans, Staphylococcus cohnii and Staphylococcus caprae. All clinical strains were clonally unrelated. Isolates carried genes encoding resistance to β-lactam (mecA) (15 %), aminoglycoside [aac(6')/aph(2″)(11 %), aph (3')-IIIa (15 %), ant(4')-Ia (19 %)] and macrolide, lincosamide and streptogramin B (MLSB) [erm(A) (4 %), erm(B) (13 %), erm(C) (41 %), msr(A) (11 %)] antibiotics...

A 67-year-old man presented to orthopaedic care with a painful knee. Workup was consistent with septic arthritis of a native knee, and the patient underwent operative treatment. Cultures from the operating room were speciated to Staphylococcus lugdunensis. To the investigators' knowledge, this is the first reported S. lugdunensis infection in a peripheral joint in the absence of an orthopaedic prosthesis. Although traditionally associated with infectious endocarditis, S. lugdunensis has been identified as a causative agent in many organ systems, including orthopaedic infections...

Cavernous Sinus Thrombosis (CST) is a rare, life-threatening condition that may result from the direct spread of infection from the nose, ears, teeth or sinuses. It is most commonly caused by Staphylococcus aureus and Streptococcus sp. We present a case of CST caused by Strepotococcus mitis and Staphylococcus lugdunensis. Early surgical intervention with aggressive medical management is needed as the syndrome carries a high mortality. To our knowledge this is the first case of CST associated with these two organisms...

Staphylococcus lugdunensis (SL) is a species belonging to the group of coagulase-negative staphylococci (CNS). It can cause severe infections such as endocarditis. Three cases of endocarditis caused by SL are presented. The first case describes a 71-year-old man with a fever and endogenous endophthalmitis. The second case describes delirium in an 87-year-old woman, thought to be due to pneumonia. The third case describes a 76-year-old man with an infection of unknown origin. In all cases, the first blood cultures drawn were positive for CNS and considered to be contaminated...

BACKGROUND: Staphylococcus lugdunensis is a coagulase-negative staphylococcus with similar virulence characteristics as Staphylococcus aureus. Whether S. lugdunensis causes infective endocarditis (IE) in a similar proportion of cases as S. aureus (reported to be 12.6% in a definitive multicenter prospective study) is unclear. METHODS: We conducted a retrospective cohort study of adult patients with at least one blood culture positive for S. lugdunensis at our institution from January 2006 to December 2014...

An 51-year-old man had undergone surgery for Rathke's cleft cyst by transsphenoidal approach on October 2015. After the surgery, cerebrospinal fluid (CSF) rhinorrhea arose. Surgical treatment of CSF rhinorrhea was performed by the same approach. Ten days after reoperation, he suffered from severe headache, high fever, and nuchal rigidity. CSF findings indicated bacterial meningitis. CSF culture showed methicillin-resistant Staphylococcus lugdunensis. He received vancomycin intravenously for 19 days and recovered from the bacterial meningitis with no serious complication...

Procalcitonin (PCT) and C-reactive protein serve as biomarkers of infection in patients with sepsis/bacteremia. The present study assessed the clinical characteristics of 280 patients with suspected sepsis who were admitted to Tohoku Medical and Pharmaceutical University Hospital between January 2012 and December 2013. Among the patients, 133 and 147 were positive and negative for PCT, respectively. Patients who were PCT positive were older and more frequently male, had reduced levels of platelets and albumin, and increased levels of aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, creatinine, and C-reactive protein...
