Abstract
Faithful to the study: middle ear infection is one of the important diseases that affect all age groups and both sexes. As it is the main cause of hearing loss in children, which affect the process of learning speech and language and the level of intelligence of the child. Objective of the study: The aim of this study is to diagnose causes of bacterial infection of the middle ear and causes compared to those of acute and chronic. As well as the study of some virulence factors and the effect of wax as a material disincentive to the growth of germs. How It Works: The study included the collection (180) swab permission from the patients with middle ear Boukmj auditors to the clinic Advisory / Division of ear, nose and throat in a hospital in Baquba / Diyala province, during the period from 1/11/2004 until 5/30/2005 were distributed among cases between 94 (52.2%) were male and 86 (47.8%) were females. The diagnosis of infection-causing isolates by methods approved standard has been conducting studies of other virulence factors such as studying and study the effect of the ear wax material. Results: Results showed that the bacterium Pseudomonas aeruginosa was the cause of the most common infection of the middle ear as it was isolated 52 (30.6%) cases, followed by both Proteus mirabilis and aureus Staphylococcus as the number of isolates 30 (17.64%) and 24 (14%), respectively . Showed 17 (70.83%) isolates of S. aureus their ability to produce an enzyme Alpittalaktaz, followed by the bacterium Proteus mirabilis as it showed 18 (60%) isolates of their ability to produce an enzyme Alpittalaktaz came bacterium P. aeruginosa ranked third as the percentage of isolates producing enzyme (59.6%). showed 22 (91.7%) isolates of S. aureus and 44 (84.6%) isolates of P. aeruginosa Alheimolaesen their ability to produce, and Proteus mirabilis was ranked third as the percentage of isolates producing Imolaesen (80%). Showed 25 (83.3%) isolates of Proteus mirabilis 41 (78.8%) of isolates aeruginosa p. Epithelial cell adhesion ability of man, and showed 9 (37.5%) isolates of S. aureus viability of epithelial cell adhesion to humans results showed influential disincentive to waxy substance produced by the ear on the growth of 9 (45%) isolates of P. aeruginosa did not appear in 11 (55%) any impact on that article. Conclusions: found that the bacterium Pseudomonas aeruginosa was the most common bacterial causes "in the middle ear infection, while chronic emerged streptococcuse spp. more frequent" in the acute infection. Isolates also showed its ability to produce one or more of the virulence factors and adhesion factors, and observed the impact of material detachment of ear wax on the growth of germs that cause infection.
