The study aims to develop a pediatric antibiogram to inform antibiotic treatment for ear infections in the community.
Collected data from patients under 18 years with ear specimens submitted to LifeLabs BC from 2020 to 2024.
Included 2338 ear specimens, focusing on organisms with at least 30 isolates for analysis.
Conducted antimicrobial susceptibility testing on identified pathogens.
Commonly identified pathogens included MSSA, MRSA, GAS, Pseudomonas aeruginosa, S. pneumoniae, and H. influenzae.
Beta-lactam antibiotics showed over 90% efficacy against MSSA, GAS, and S. pneumoniae.
Clindamycin and erythromycin had lower sensitivity against MSSA and MRSA.
Trimethoprim-sulfamethoxazole showed high susceptibility rates for MSSA and MRSA.
