INTRODUCTION: Acute salivary gland infections (ASI) have been associated with poor outcome in elderly and postoperative patients. Perioperative care and treatment of co-morbidities have improved considerably, but most of our knowledge regarding ASI dates back several decades. The aim of this study was to describe the microbiology and treatment of ASI in a large post-millennial cohort. METHODS: All patients with ASI admitted to the Department of Otorhinolaryngology – Head and Neck Surgery, Aarhus University Hospital in the period from 2001 to 2017 were included. RESULTS: In total, 157 patients with ASI were included. The parotid gland (PG) was affected in 89 (57%) cases and the submandibular gland (SMG) in 68 (43%) cases. The most prevalent bacterial findings were viridans streptococci (25 isolates) and Staphylococcus aureus (19 isolates). S. aureus was almost exclusively found in PG (17/19 cases). S. aureus-positive cases showed a significantly higher inflammatory response than other bacteria (C-reactive protein, p = 0.008 and absolute neutrophil count, p = 0.0108). CONCLUSIONS: S. aureus is a significant pathogen in ASI and especially in PG cases. Other pathogens may play a role in the development of SMG infections. Based on the bacterial findings in this study, we recommend penicillinase-resistant penicillin as first-line treatment in ASI.
