Culture-guided management of proliferative necrotizing otitis externa in a cat

Abstract

This case report describes the diagnosis and long-term management of bilateral necrotizing otitis externa in an 11-month-old cat. Clinical, cytological, and microbiological findings supported a presumptive diagnosis of proliferative and necrotizing otitis externa (PNOE). Microbiological culture identified multidrug-resistant Pasteurella multocida and Staphylococcus intermedius. A seven-month, culture-guided treatment using topical and systemic antimicrobials helped resolve secondary bacterial infections. Complete clinical and microbiological resolution was achieved, with no recurrence observed. This case shows that targeted antimicrobial therapy can support recovery in complicated PNOE cases.
