AbstractThis study was carried out to evaluate the relation between the causative agents of otitis media and the parameter related to the patients (e.g., gender, age) the criteria of causative agents include type of bacteria, growth conditions, susceptibility to antibiotics, and the ability to produce ß-lactamase enzymes. A total of 50 ear swabs were obtained from outpatients infected with otitis media.
The results showed that Staphylococcus epidermidis (30%) was the predominant pathogens followed by Staphylococcus aureus (20%), Pseudomonas aeruginosa (18%), Proteus mirabilis (8%), and Proteus vulgaris (4%). The antimicrobial susceptibility pattern showed that all bacteria were resistant to cephalothin and moderate resistant to other antibiotics.
For detection of ß-lactamase producing bacteria, results showed that Ps. aeruginosa was recorded a high percentage in producing of ß-lactamase enzymes (55.6 %) in comparison with the other bacteria.
