Properties of Staphylococcus lugdunensis in Children

摘要

Background. Staphylococcus lugdunensis is one of the clinically important coagulase-negative staphylococci. The purpose of this study was to elucidate the microbiological features of S. lugdunensis in hospitalized children. Methods . From January 2012 to December 2019, all isolates were retrospectively screened for S. lugdunensis. Results . Twenty-five children were eligible for study. Nineteen and six children were classified into a critical care unit group (Group A) and a general medical ward group (Group B), respectively. The prevalence of methicillin-resistant S. lugdunensis was significantly higher in Group A than in Group B (68.4% vs 0%; P ??.01). Eleven children (44%) had S. lugdunensis infections, while the remaining children were colonized. Six of the 11 infected children (55%) had healthcare-associated infections. Moreover, 3 isolates exhibited the methicillin resistance. Conclusions . The bacteriological characteristics of S. lugdunensis differ depending on patient background. Selection of antibiotic treatment should in part rely on patient background data.
