Abstract

BACKGROUND Influenza B viruses cause seasonal epidemics of respiratory illness, circulating concurrently with influenza A viruses. However, virological and clinical knowledge of influenza B viruses is less well advanced than for influenza A, and in particular, complications associated with influenza B infection are not as commonly reported. Complications of influenza B infection predominantly include neurological and musculoskeletal pathologies, while a review of the literature shows that bacterial infections associated with influenza B viruses often involve Gram-positive organisms, with a smaller subset featuring Gram-negative species. CASE REPORT In this case report we highlight an uncomplicated infection of the urinary tract by Escherichia coli immediately following influenza B infection, in an otherwise healthy adult white male with no prior history of urinary tract infection or structural abnormalities of the renal tract. CONCLUSIONS Bacterial infections complicating influenza B infection may include organisms not commonly associated with the respiratory system, such as Escherichia coli. In addition, bacterial complications of influenza B infection may affect non-respiratory systems, including the genitourinary tract.
