Answer

K rhinoscleromatis and K ozaenae cause rhinoscleroma and ozena, respectively. Both are rare in the United States and are associated with upper respiratory infection.

Rhinoscleroma is a chronic granulomatous infection. Patients present with a purulent nasal discharge with crusting and nodule formation that leads to respiratory obstruction. Diagnosis is aided by histology findings and positive results from blood culture.

Ozena is a primary atrophic rhinitis that often occurs in elderly persons. Common symptoms include nasal congestion and a constant nasal bad smell. Patients also may complain of headache and symptoms attributable to chronic sinusitis. Unlike rhinoscleroma, nasal congestion is not a prominent feature.
