Infections due to Achromobacter xylosoxidans. Case report and review of the literature.
Achromobacter xylosoxidans is an uncommon nosocomial pathogen known to cause many serious infections. A 69-year-old woman with diabetes mellitus and chronic renal failure was admitted with pulmonary edema. The patient developed fever and pulmonary infiltrate with bilateral pleural effusions while she was on a respirator in the intensive care unit. Culture of sputum, pleural fluid and blood grew A. xylosoxidans. Bilateral chest tubes were inserted and the patient was treated for one month with piperacillin and trimethoprim-sulfamethoxazole. Gradual response, both clinically and radiologically, was noted after prolonged therapy. A review of the literature on infections due to A. xylosoxidans, the unique susceptibility pattern of the organism to various antibiotics and the use of combination therapy in Achromobacter infections are discussed.
