호중구 감소증의 과거력이 있는 소아에게 발생한 Achromobacter xylosoxidans 균혈증 1예

Abstract

Achromobacter xylosoxidans is a non-fermentative, aerobic, oxidase, and catalase-positive Gram-negative rod similar to Pseudomonas species. This organism colonizes aquatic environments and can cause nosocomial infections, especially in patients with immune deficiency such as human immunodeficiency virus infection, cancer, cystic fibrosis, neutropenia, and immunoglobulin M deficiency. Infections are found as bacteremia, pneumonia, meningitis, urinary tract infection, abscess formation, and osteomyelitis. It is known that most effective antibiotics are piperacillin/tazobactam, meropenem, and trimethoprim/sulfamethoxazol. But there is no optimal antibiotic therapy so far. We present a case of Achromobacter xylosoxidans bacteremia in a 13-month-old Korean girl who had past history of neutropenia.
