Abstract
ObjectiveTo investigate the clinical distribution and the drug resistance of Staphylococcus lugdunensis.
MethodsTotal of 34 strains from the 261st Hospital of the People’s Liberation Army and Haidian Hospital of Beijng were collected. Staphylococcus lugdunensis were identified by VITEK-2 Compact and MALDI-TOF MS apply protein mass spectrometry. The drug resistance was analyzed by Gram-positive bacteria susceptibility test product VITEK-2 AST-GP67 Test Kit and WHONET 5.6 and the statistical analysis were performed by Fisher exact probabilities.
ResultsWound secretion due to skin and soft tissue infections, accounting for 47%; following by bone and joint infections, breast diseases and gynecological diseases, account for 9%, then following by bloodstream infections, ear problems, nose diseases and urinary system infections, account for 6%. The resistance of Staphylococcus lugdunensis to penicillin reached 91%, but it was sensitive to most other antibacterial medicines. Positive bacteria strains of Methicillin-resistant Staphylococcus lugdunensis account for 32%. There was no significant difference of the resistant rates to antibacterial drugs between patients in the positive group and negative group.
ConclusionsThe infection sites of Staphylococcus lugdunensis were mainly in skin, tissues, breast bone, joint, none, ears and genitourinary region, and were sensitive to most of the clinical antibiotics.
