Sixty (60)
samples from both hospitalized and ambulatory patients
seeking medical care in University of Uyo Teaching Hospital
(UUTH) and Nedeke Peadiatric Hospital (NPH) in Uyo were
screened for the microorganisms associated with otitis media
between June and December, 2007. The number of occurrence of
bacterial species out of the total isolates ranged from 1
and 15 with the percentage frequency between 1.49 and
22.38%. The following Bacteria were isolated from
otitis media samples: Moraxella spp.,
Streptococcus spp., Staphylococcus spp.,
Bacillus spp. and Escherichia coli, with a
predominance of Streptococcus spp. The number of
occurrence of fungal species in the samples ranged between 1
to 18 with the percentage frequency between 2.04 and 20.4%.
Fungi isolated from otitis media samples were Aspergillus
spp., Rhizopus spp., Cephalosporium spp.,
Penicillium spp., and Candida spp.,
with Aspergillus spp. predominating. Forty nine
patients (81.6%) had a single organism isolated from the
middle ear culture, while the remaining 11(18.4%) patients
had two or more organisms isolated. Infection was highest
among the 1 - 10 years, and the lowest among aged 31 and
above. The study revealed that there were higher numbers of
bacteria associated with otitis media than fungi in Uyo.
