Introduction.Fannyhessea vaginae (formerly Atopobium vaginae) is an anaerobic organism commonly associated with female genital flora, with rare cases of invasive disease reported in females. Case report. We discuss the case of an 81-year-old male who presented with an acute history of back pain and signs of urinary tract infection in the context of intermittent self-urinary catheterisation. Multiple blood cultures grew Fannyhessea vaginae with a later finding of lumbar vertebral osteomyelitis as the cause of back pain. Treatment was commenced with ampicillin, later switched to ceftriaxone, with improvement of acute signs of infection. Conclusion. Gram-positive anaerobic organisms including Fannyhessea vaginae are possibly under-recognised causes of urinary tract particularly in older males. These bacteria may prove challenging to grow in standard protocols for urine culture; anaerobic or extended incubation could be considered particularly in complicated cases of urinary tract infection without an identifiable pathogen.
