Staphylococcus lugdunensis Skin Infection: Report of 16 Cases.

INTRODUCTION AND OBJECTIVE

Staphylococcus lugdunensis belongs to the group of coagulase-negative staphylococci. The aim of this report was to review the clinical and microbiologic features of cases of S. lugdunensis skin infections.

MATERIAL AND METHODS

Observational study of all cases of skin infections in which S. lugdunensis was isolated by the microbiology department of Hospital General San Jorge in Huesca, Spain, between 2009 and 2016.

RESULTS

We studied the cases of 16 patients. The most frequent site of infection was the inguinal-perineal region (n=6, 37.5%), and pustules were the most common presentation (n=5, 31.3%). Response to treatment was good in 87.6% of the patients (n=14). However, infection recurred in 3 patients, 2 of whom were on anti-TNF therapy.

CONCLUSIONS

S. lugdunensis should be considered a possible cause of infection when it is isolated in both skin and subcutaneous tissues, especially in patients on biologic therapies.
