    Abstract

    The aim of this study was to describe the burden and organism antibiotic resistance patterns of skin and soft tissue infections (SSTI) due to Staphylococcus aureus presenting in a remote Australian Northern Territory community in the Barkly region. We collated reported antibiograms of all skin and superficial soft tissue swab specimens obtained from the town's Indigenous medical clinic from 12 of the 13 months between November 2016 and December 2017. Clinician's notes for the consultation associated with each test request were examined to determine the nature of the clinical problem and to access other relevant data. Amongst 309 tissue swab specimens, S. aureus was cultured in 215 (70%), of which 202 isolations were from Indigenous Australians. Of the 215 S. aureus, 98 [46%, 95% confidence interval (CI) 31–52] were methicillin resistant S. aureus (MRSA) and 117 (54%, 95% CI 48–61) sensitive (MSSA). Significant numbers were also resistant to other frequently used oral antibiotics, with resistance to erythromycin in 52 (24%), clindamycin in 51 (24%), trimethoprim in 22 (10%) and fusidic acid in eight (4%). In the Barkly region of Australia's NT in 2017, community-acquired staphylococcal SSTI needing professional care is equally likely to be caused by MRSA as by MSSA.
