Objectives: Staphylococci were most prominent factors that responsible for skin, soft tissue and foreign body infections. Gaining resistance to methicillin and various antibiotics in these microorganisms over the years increased morbidity and mortality, especially in hospitalized patients. In such situations number of preferred antibiotics was limited. The aim of this study was to investigate i...

Six cases of chronic endophthalmitis following extracapsular cataract extraction and lens implantation are reviewed. All were referred for tertiary management by one surgeon over a period of just over 2 years. In two of the cases coagulase negative staphylococci were isolated and in three Propionibacterium spp were retrieved. In the remaining case a mixed growth of coagulase negative staphyloco...

Absorbed antisera prepared against heat-killed suspensions of a coagulase-negative staphylococcus and of a micrococcus were used in a slide-agglutination test. A collection of 176 coagulase-negative aerobic cocci, from which Staphylococcus aureus had been excluded, was classified into staphylococci and micrococci by means of the test for anaerobic utilization of glucose. Of 113 staphylococci, 9...

This study evaluated the possible advantages provided by a genotypic method over commercially available biochemical systems for the identification of clinical isolates of coagulase-negative staphylococci (CNS). Partial sequencing of the sodA gene was performed for 168 coagulase-negative clinical isolates of staphylococci identified previously with the ID32 STAPH system. Of these, 101 (60.1%) we...

Catheter related bloodstream infections are a major problem in most tertiary care hospitals. Among the various organisms associated with nosocomial infections, coagulase negative staphylococci are responsible for majority of the catheter related infections. They are usually resistant to standard antibiotics necessitating prolonged hospital stay and amplifying the cost of treatment manifold whic...

Erik Ahlstrand (2013): Coagulase-negative Staphylococci in Hematological Malignancy. Örebro Studies in Medicine 95. Bacterial infections are common in hematological malignancy. Coagulasenegative staphylococci (CoNS) are among the most prevalent causes of bacteremia in patients with hematological malignancies. In this thesis, different aspects of CoNS in hematological malignancy have been studie...

Neonates, especially those born prematurely, are at high risk of morbidity and mortality from sepsis. Multiple factors, including prematurity, invasive life-saving medical interventions, and immaturity of the innate immune system, put these infants at greater risk of developing infection. Although advanced neonatal care enables us to save even the most preterm neonates, the very interventions s...

Nasal surveillance cultures were performed for 54 patients exhibiting >/=10(3) CFU of methicillin-resistant coagulase-negative staphylococci per ml in central venous catheter (CVC) rinse cultures over a 6-month period. Forty-two of the nasal cultures yielded growth of methicillin-resistant coagulase-negative staphylococci, and 33 of the 42 cultures contained organisms that belonged to the same ...

A case of Staphylococcus lugdunensis endocarditis is presented with low back pain suggesting a secondary bone focus of infection. An umbilical skin lesion may have been an additional embolic phenomenon. The case highlights the aggressive nature of S lugdenensis endocarditis compared with other coagulase negative staphylococci and its association with native heart valves. In addition the importa...

Coagulase negative staphylococci (CNS) were a rare cause of native valve endocarditis. However, they are emerging as an important cause of native valve endocarditis (NVE) in both community and healthcare settings. We describe a 64 yrs. old male who developed mitral valve endocarditis caused by coagulase negative staphylococci. There were no predisposing conditions or underlying cardiac disease ...
