Actinobaculum schaalii is a uropathogen resistant to ciprofloxacin and trimethoprim-sulfamethoxazole.
It requires a long culture time and specific conditions, and is therefore easily overgrown by other bacteria and regarded as part of the normal bacterial flora. We review 17 cases of A. schaalii bacteraemia, demonstrating its invasive potential. A. schaalii should always be ruled out as causative agent in patients with urinary tract infection or urosepticaemia with treatment failure.
