Antimicrobial Profile of Bacterial Isolates from Patients with Acute Otitis Media in Hadhramout-Yemen
Main Article Content
Abstract
Abstract
Acute Otitis Media (AOM) becomes challenges especially in resource constrained countries because it is commonly associated with bacteria that have multiple drug resistance. This study was aimed to identify bacterial agents of AOM and determine their antimicrobial patterns.
Methods: Hundred ear swabs were collected from patients who attended the outpatient’s clinics of Ear Nose Throat in Mukalla city, Hadramout, Yemen, during the period from August 2021 till March 2022, the samples were diagnosed phenotypically, then their antibiogram was evaluated by Bauer-Kirby method.
Results: The prevalence of acute otitis media was 60%. The most common isolated bacteria were Staphylococcus aureus (45%), Pseudomonas aeruginosa (31.7%), Proteus mirabilis (13.3%), Escherichia coli (5%), Klebsiella pneumonia (3.3%), and Streptococcus pneumoniae (1.7%). The antibiogram showed that Levofloxacin was the most effective agent against all isolates, followed by Ciprofloxacin with rate of %100, 63.3%, 62.5%, 66.7%, 73.7% for Klebsiella pneumonia, Pseudomonas aeruginosa, S. aureus, Pseudomonas mirabilis and Escherichia coli respectively, while Streptococcus pneumonia was resistant to it. All isolates were resistant to Cephalexin, Ceftazidime and Aztreonam (100%), while Streptococcus pneumonia was sensitive to Cephalexin. Furthermore, our findings demonstrated seven resistant patterns of the isolates.
Conclusion: The isolation rate of bacteria in samples of AOM is still high and combined with substantial resistance rate among bacterial isolates of AOM to the antibiotics under study. The high resistance rate reflects the widespread abuse of antimicrobial agents in our community, emphasizing the need for strict antimicrobial control measures and updating the empirical antimicrobial prescription guideline.
