Background: Acute suppurative parotitis (ASP) of neonates is a rare condition characterized by irritability, erythema, and tenderness of the affected gland. Methods/Results: Only few cases have been reported in Engilsh literature, mostly in male neonates, in a unilateral fashion. In our case, a polymicrobial etiology (Klebsiella pneumoniae, Staphylococcus aureus, Acinetobacter ursingii, and Acinetobacter junii) was found. Based on the review of the microbiological findings of cases of ASP in English literature for the years 1970 to 2020, S. aureus is the most commonly isolated microorganism (47% of the total 65 patients). Our patient was born with a C-section procedure and was not breast-fed, making dysbiosis along with the usage of the feeding bottle, possible risk factors for the development of ASP. Conclusions: ASP may be due to polymicrobial etiology. Initial presentation in neonates may not include typical signs and symptoms, like fever. Aseptic technique of oral procedures is of utmost importance also in immune-competent neonates.
