Chronic Nasal Infection Caused by Klebsiella Ozaenae

Background and Aim : Klebsiella Ozanae is associated with chronic diseases of upper airway ozanae meaning stench. It is a rare progressive chronic rhinitis characterizes by a trophic changes in the nasal with resorption of the underlying bone formation of thic and greenish crust and a distinct fetid odor.Methods : A ۳۶ years old woman presented with a crusting rhinitis and foul greenish discharge mainly from the right nostril. She complained of bad nose smells.The nasal discharge specimens were inoculated on to sheep blood agar , chocolate agar , Mackonkey agar and thioglycolate broth and incubated at ۳۷° in a ۵% Co۲ atmosphere . Identification was performed by using biochemical reactionsResults : After ۲۴h of incubation on blood agar, chocolate agar, Mac agar revealed abundant growth of mucoid colonies . biochemical characteristics showed urease(-), indole (-) , MR (+), VP (-) , citrate (+), Lysin decarboxylase(-), motility(-). Antimicrobial susceptibility test showed resistant to Amoxicilin , Trimethoprime and Sulfamethoxazole.Conclusion : The incidence of ozanae is little in developed countries . It is doubtless more common in developing countries . Ozanae has be reported to account for ۰.۳ – ۷.۸% of ear, nose and throat diseases in endemic areas. A low index of suspicion in non endemic areas could explain the delay in in its diagnosis and its management . This bacteria are not included in routine analyses. It was isolated because the physicians were aware of ozanae.
