title: [Catheter- associated bacteremia caused by Ochrobactrum anthropi].
abstract: Ochrobactrum anthropi is a non-glucose fermentative, aerobic gram-negative bacillus, formerly known as Achromobacter sp or CDC group Vd. It has been isolated from the environment and from infections in usually immunocompromised human beings. The documented infections frequently involved catheter related bacteremia whereas endophthalmitis, urinary infections, meningitis, endocarditis, hepatic abscess, osteochondritis, pelvic abscess and pancreatic abscess were rarely involved. Here it is presented the case of a male patient aged 69 years with sustained hypotension, four day febrile syndrome, chill, lavish perspiration and sensorium deterioration. He had type 2 diabetes and antecedent of cerebrovascular accident. A double-lumen dialysis catheter was present due to chronic renal insufficiency. An episode of catheter-related bloodstream infection was documented by using Bact-Alert Blood Culture System and Differential-Time-to-Positivity Method for central venous catheter versus peripheral blood cultures (>120 min). Once removed, it was confirmed through Maki semi quantitative technique (>15 FCU). The microorganism was identified by API 20NE and Vitek 1 as Ochrobactrum anthropi.
