Background: Otitis Media is inflammation of the middle ear. This is most communally
caused by buildup of fluid behind the ear drum, as a result of blockage to the Eustachian
tube. It can cause mild to moderate hearing loss, due to the fluid interfering with the
transmission of sound through to the inner ear, and constitutes the most common
respiratory tract infection of infancy and early childhood.
Objective: To study the etiological agents and antibiotics sensitivity of Otitis Media in
children admitted to a Central Pediatric Teaching Hospital.
Methods: This study included 60 patients having signs and symptoms of otitis media who
were admitted to a Central Pediatric Teaching Hospital in Baghdad city. Samples were
obtained during the period from the 1st of December 2012 till the 30th of March 2013.
Middle ear fluid samples for all children were collected by an ENT specialist either by
tympanocentesis procedures or otorrhea swabs. Isolation and Identification of causative
microorganism by colonial morphology, Gram stains. Biochemical tests for Gram positive
bacteria: Catalase, coagulase test. Tests used for Gram negative bacteria: Indol, methyl
red, Vogas-Proskauer, citrate utilization (IMVIC Test), oxidase, urease, motility test and
susceptibility of bacteria to antibiotics and chemotherapeutic agents.
Results: Twenty-eight (100%) patients gave positive culture, and 32 (100%) patients gave
negative culture. The majority of microorganisms isolated from cultures positive patients
were Staphylococcus aureus 8 (28.8%) followed by Pseudomonas spp 7 (25.0%), Proteus
spp 3 (10.7%), Klebsiella spp 3 (10.7%), Escherichia coli 2 (7.1%), Haemophilus influenza
2 (7.1%), Streptococcus pneumonia 2 (7.1%), Enterobacter 1 (3.5%).
Conclusions: More than 50% of otitis media in children caused by the Gram positive and
Gram negative bacterial isolate such as Staphylococcus aureus and Pseudomonas spp
among age 1 day - 4 years of age, in female more than male, more in urban area, The
antibiotics (Cefotaxime, Amoxicillin- Clavulanic acid, Clindamycin, Ceftriaxone) are the
most effective against Staphylococcus aureus and (Amikacin, Gentamycin, Ceftazidine)
are most effective against Pseudomonas spp.
