Isolation and Antibiotic Susceptibility of Bacteria from Otitis Media Infections in Children in Rabat Morocco

An inflammation of the middle ear by bacteria, viruses or champignons is called otitis media. The objective of this study was to determine the microbial etiology of otitis media in children in Rabat, and susceptibility pattern commonly prescribed antibiotics. Samples of ear swabs were collected from patients at the pediatric hospital, CHU Ibn Sina Rabat, during the period between February 2012 and March 2013. The total number of isolates was 67 (66 bacteria and Candida spp 1). Of these 66 bacteria spp, Streptococcus pneumoniae was the highest number (27) followed by Pseudomonas aeruginosa (16), Staphylococcus aureus (15), Escherichia coli (3), Klebsiella spp (3), Proteus species (2), and candida spp (1). This study out showed that the peak incidence was found in the age group 0-5 years (62,69%), followed by the group 5-10 years (20.90%), by cons, the group age 10-16 years was a rate of 16.41%. All bacteria were resistant to penicillin. . Pseudomonas aeruginosa, Escherichia coli and Klebsiella spp were resistant to certain antibiotics such as ofloxacin, amoxicillin, amoxicillin+clavulanic-acid, levofloxacin and cefuroxime. All strains of streptocoques pneumoniae were sensitive to ciprofloxacin, but all resistant to amoxicillin, cefuroxime and penicillin. All strains of Proteus spp were susceptible to ciprofloxacin, levofloxacin, ofloxacin, only resistant to amoxicillin. Accordingly, sufficient knowledge of the antibacterial susceptibility of bacteria, the judicious use of antibiotics and the periodic evaluation of the resistance profile of antibiotic sensitivity in the region is very important in order to avoid failure in the treatment of otitis media in children.
