The addition of clotrimazole reduces but does not abrogate fungal dysbiosis during effective antibacterial therapy for canine otitis externa.

Clinical Context

Peer-reviewed veterinary literature continues to shape everyday decision-making for canine patients, especially when new evidence clarifies diagnosis, treatment selection, monitoring, or clinical outcomes.

What the Study Evaluated

A study published in The Journal of small animal practice in 2026 evaluated the addition of clotrimazole reduces but does not abrogate fungal dysbiosis during effective antibacterial therapy for canine otitis externa..

Key Findings

Malassezia dysbiosis commonly occurs after successful piperacillin-tazobactam monotherapy for canine bacterial otitis externa. The study objective was to compare antimicrobial outcomes in dogs with otitis treated with piperacillin-tazobactam in combination with the antifungal drug clotrimazole with a previous cohort treated with piperacillin-tazobactam alone. Twenty-one dogs with bacterial otitis were treated topically with piperacillin-tazobactam (1 mL) every 12 hours, although the fourth dose in each 48 hours period was replaced with 1% clotrimazole solution (1 mL). At visits 1 (V1) and 2 (V2), ear swab tips were washed in PBS + Triton...

Why It Matters for Veterinary Professionals

For veterinary professionals, the practical value of this work lies in how the findings may support more structured clinical assessment, clearer monitoring, and more informed decisions for canine patients.

Practical Interpretation

The results should be interpreted in the context of the study design, population, inclusion criteria, and clinical setting. Application in practice should consider patient-specific risk factors, available diagnostics, local standards of care, and clinician judgment.

Clinical Takeaway

Overall, the study adds useful evidence for clinicians seeking to align daily practice with current veterinary research while maintaining a balanced, case-by-case approach.
