Acute bacterial parotitis is typically treated empirically with which class of antibiotics?

• A. Beta-lactam antibiotics
• B. Macrolide antibiotics
• C. Fluoroquinolone antibiotics
• D. Tetracycline antibiotics

Answer: (A)

Acute bacterial parotitis is usually caused by oral flora that include Staphylococcus aureus and viridans streptococci, with possible anaerobic organisms in mixed infections. Empiric therapy needs reliable coverage of these common Gram-positive cocci and the accompanying oral anaerobes. Beta-lactam antibiotics fit this need well, especially options like penicillinase-resistant penicillins or beta-lactamase–inhibitor combinations, which provide strong activity against Staphylococcus aureus and Streptococcus species and can extend to anaerobes when indicated. This makes them the most appropriate initial choice while awaiting culture results. Macrolides often lack reliable coverage against Staph aureus due to resistance; fluoroquinolones offer broader coverage but aren’t as consistently effective for this specific infection and carry more risks; tetracyclines are not ideal for acute parotitis due to resistance and adverse effects.
