Abstract:
Historically, Staphylococcus aureus has been the primary pathogen in acute suppurative parotitis (ASP). This report presents an index case of Pseudomonas aeruginosa bacteremia associated with ASP and an institutional review of parotitis in which three of 23 additional cases of pyogenic parotitis had enteric bacilli cultured either alone or as the primary pathogen. These cases support the previously undocumented supposition that enteric gram-negative bacilli and pseudomonads can be pathogens in ASP.
Insights
Staphylococcus aureus is often the cause of acute suppurative parotitis (ASP). However, this study found that Pseudomonas aeruginosa and enteric gram-negative bacilli can also cause ASP, expanding the known pathogens for this infection.
Area of Science:
- Infectious Diseases
- Microbiology
- Otolaryngology
Background:
- Acute suppurative parotitis (ASP) is typically caused by Staphylococcus aureus.
- Understanding the spectrum of pathogens in ASP is crucial for effective treatment.
Observation:
- An index case of Pseudomonas aeruginosa bacteremia linked to ASP was identified.
- A review of 23 additional pyogenic parotitis cases revealed three with enteric bacilli.
Findings:
- Enteric gram-negative bacilli and pseudomonads were identified as potential pathogens in ASP.
- This challenges the historical assumption of Staphylococcus aureus as the sole primary pathogen.
Implications:
- The findings suggest a broader range of causative agents for acute suppurative parotitis.
- This may necessitate adjustments in diagnostic and therapeutic strategies for ASP.
