Agrobacterium radiobacter (A. radiobacter) is an aerobic, gram-negative bacillus that is an uncommon cause of disease but has been increasingly associated with catheter related infections in immunocompromised patients. Definitive information regarding effective treatment strategies is currently lacking; however, many A. radiobacter isolates are only susceptible to broad- spectrum antibiotics. We report a patient with A. radiobacter catheter infection who failed to improve on antibiotic therapy that displayed in vitro activity but did improve upon removal of the catheter and hub. Summaries of published case reports and susceptibility results are presented along with a discussion of empiric treatment strategies. Irrespective of the role of catheter removal, use of either imipenem/cilastatin or a quinolone appears appropriate based on literature reports and susceptibility data accumulated to date.
