Abstract

BACKGROUND Otitis media (OM), also known as middle ear infection, is a clinically significant childhood disease. In sub-Saharan Africa, there is a paucity of contemporary reports on it is bacterial aetiologies and antimicrobial resistance among them. AIM To investigate the OM bacterial aetiologies and their antimicrobial resistance patterns among children visiting the Ear, Nose, and Throat clinics of 3 healthcare facilities in Accra, Ghana - Princess Marie Louise Children's Hospital, 37 Military Hospital, and Mamprobi Hospital. METHODS This cross-sectional study involved 100 children below 13 years old with suppurative otitis media. Following standard bacteriological methods, sterile ear swabs were used to take middle ear discharges from the study participants for culture and antimicrobial susceptibility testing. A standard questionnaire was also used to collect data on socio-demographic and clinical characteristics. RESULTS The major OM bacterial aetiologies were Pseudomonas aeruginosa (38.5%), Klebsiella pneumoniae (19.8%), Proteus mirabilis (11.5%), and Staphylococcus aureus (10.4%). The majority of the bacteria demonstrated low to moderate resistance (0%-33.3%) to most of the antibiotics. Eight of the bacteria (4 each of Klebsiella pneumoniae and Escherichia coli) were extended-spectrum beta-lactamase (ESBL) producers; 6 ampicillinase (Amp C)-producing organisms (4 Citrobacter spp. and one each of Morganella morganii and Serratia marcescens) were also identified, and they showed high antibiotic resistance. CONCLUSIONS The predominant OM aetiologies were Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus mirabilis, and Staphylococcus aureus, and they were generally susceptible to most of the antibiotics tested. Amikacin, cefepime, ciprofloxacin, and meropenem could be valuable in the empirical management of childhood OM.
