Bacteremia and urogenital infection with Actinomyces urogenitalis following prolonged urinary retention

A case of bacteremia with the fastidious bacteria Actinomyces urogenitalis following lengthy urinary retention is reported in a sixty-year-old man. In 2013, the first case of bacteremia due to A. urogenitalis was presented, secondary to a tubo-ovarian abscess following transvaginal oocyte retrieval. To the best of our knowledge, this is the first male bacteremic episode involving A. urogenitalis related to a urinary tract focus. The patient had no prior urogenital medical history. Extensive susceptibility testing was done on isolates from urinary and blood cultures. The organism exhibited fluoroquinolone resistance but was susceptible to most other antibiotics used in the treatment of urinary infections. Due to its unusual growth requirements infections with A. urogenitalis are most likely an underdiagnosed entity.
