Abstract:
Atopobium rimae, previously Lactobacillus rimae, is a strictly anaerobic, non-spore forming grampositive rod which was frequently isolated from odontogenic infection. We report a case of A. rimae bacteremia. A 47-yr-old man with liver cirrhosis was admitted to the hospital via emergency room due to fever and chill. His abdominal and pelvic computed tomography revealed a small abscess near the left adrenal gland. Three sets of blood cultures were taken and non-spore forming, grampositive rods were detected in all anaerobic vials. This isolate grew small nonhemolytic, gray-white translucent colonies on Brucella blood agar and was obligatory anaerobic on air-tolerance test. This organism was negative for catalase, indole, nitrate-reduction and beta-lactamase and failed to identify by Vitek ANI card (bioMerieux, France). 16S rRNA sequences of this showed 99.8% homology of the published sequence of A. rimae (GenBank accession number AF292371). Aspirates of periadrenal abscess grew Escherichia coli and Peptostreptococcus micros. He was treated with metronidazole and imipenem and follow-up cultures of blood were negative at days 4 and 10. To our knowledge, this is the first report of bacteremia of A. rimae.
