The study aimed to create an antibiogram from community-collected ear culture isolates to inform antibiotic selection for ear infections.
Retrospective analysis of outpatient ear culture data collected from communities in British Columbia.
Antibiotic susceptibility was assessed for various pathogens using the collected data.
Statistical analysis was conducted to evaluate sensitivity rates of different antibiotics against specific bacteria.
Beta-lactam antibiotics exhibited 90% or greater sensitivity against MSSA, GAS, and S. pneumoniae.
Clindamycin and erythromycin had lower sensitivities of 84% and 82% against MSSA, respectively, and 79% and 50% against MRSA, respectively (p < 0.001).
Trimethoprim–sulfamethoxazole and tetracycline showed high susceptibility rates of 99% and 97% for MSSA and 94% and 85% for MRSA, respectively.
