      Family: Aerococcaceae

      Natural habitats
      A. urinae is a rarely reported pathogen, possible due to the difficulties in the identification of the organism.

      Clinical significance
      Isolates of this species were originally isolated from the urine of patients with urinary tract infections and were denoted Aerococcus-like organisms.

      Infections with this bacterium has likely been underestimated.

      A. urinae may also cause invasive infections including urosepsis, lymphadenitis, spondylodiscitis and infective endocarditis especially in elderly men with underlying urinary tract diseases.

      Facultatively anaerobic

      Colonies are small (0.5 mm after 24 h), α-hemolytic, convex, shiny, transparent and non-hemolytic on blood agar.

      Greening reaction is produced on bloodagar presumably as a result ot H2O2 productions.
