Antimicrobial susceptibility pattern of clinical isolates from cases of ear infection using amoxicillin and cefepime

Area of Science:

• Microbiology and Infectious Diseases
• Clinical Bacteriology
• Pharmacology

Background:

• Otitis media incidence is rising, potentially linked to multidrug-resistant pathogens.
• Pseudomonas aeruginosa and Staphylococcus aureus are primary causative agents of otitis media.
• Understanding pathogen sensitivity is crucial for effective otitis media treatment.

Purpose of the Study:

• To determine the antibiotic sensitivity patterns of clinical isolates causing otitis media.
• To evaluate the efficacy of cefepime and amoxicillin against common otitis media pathogens.

Main Methods:

• Clinical isolates of otitis media were collected from hospitals and laboratories in Karachi.
• Disk diffusion method was employed to assess bacterial sensitivity.
• Antibiotic susceptibility testing was performed using cefepime and amoxicillin.

Main Results:

• Pseudomonas aeruginosa was identified as the most prevalent microorganism in ear infections.
• Cefepime, a fourth-generation cephalosporin, showed significant effectiveness against both Pseudomonas aeruginosa and Staphylococcus aureus.
• Amoxicillin sensitivity data was also collected for comparison (though not detailed in the abstract).

Conclusions:

• Cefepime is a promising antibiotic for treating otitis media caused by Pseudomonas aeruginosa and Staphylococcus aureus.
• The findings highlight the importance of ongoing surveillance of antibiotic resistance patterns in otitis media.
• This research aids in guiding appropriate antibiotic selection for otitis media management.
