Effect of Ionizing Radiation on Some Microorganisms Causing Chronic Suppurative Otitis Media
Aim: To evaluate the effect of a diagnostic x-ray in vitro study on bacteria causing chronic suppurative otitis media.
Design: The number of viable cells before and after exposure to different doses of radiation was estimated.
Setting: Ear, nose, and throat department in Erbil Military Hospital and microbiology and x-ray unit in Saddam General Hospital in Mosul, Iraq, during the period from July 1999 to July 2000.
Material and Methods: The effect of ionizing radiation (x-ray) was studied on different strains of bacteria in vitro.
Results: The final results showed that there is a statistically significant reduction in the number of viable cell counts of certain microorganisms after exposure to a specific dose of radiation in vitro.
Conclusion: A single small dose of x-ray radiation (diagnostic x-ray dose) reduced the number of viable cells of certain microorganism in vitro.
