Achromobacter, an aerobic, non-fermentative, Gram-negative rod is rarely isolated from clinical material. It can be confused with Pseudomonas spp. in clinical specimens, so that its role as a significant pathogen is underestimated. This organism was first described and named by Yabuuchi in 1971. (Yabuuchi & Oyama, 1971). Seven species are currently described within the genus Achromobacter, name...

We report the case of a 35-yr-old patient who presented with high fever and chills. He had undergone a patch closure of the ventricular septal defect 18 yr before. One year later, a VVI pacemaker was implanted via the right subclavian vein because of complete heart block. Nine years after that, a new VVI pacemaker with another right ventricular electrode was inserted controlaterally and the old...

BACKGROUND Achromobacter piechaudii is a rare cause of clinical disease in humans. Previously, clinical disease has only been documented in immunocompromised patients. We present a case of Achromobacter piechaudii bacteremia in a patient with previous malignancy but no known immunosuppression. CASE REPORT A 67-year-old man with distant history of colon and prostate cancer presented with low g...

Achromobacter xylosoxidans is an aerobic, nonfermenting gram-negative rod and described as a waterborne bacterium since it habits aquatic environments ubiquitously. It has frequently been isolated from aquatic surroundings in the hospital and from various human body sites. Although occasionally considered a non-pathogen, A. xylosoxidans has been associated with outbreaks of nosocomial infection...

Achromobacter xylosoxidans is a Gram-negative aerobic bacterium first described by Yabuuchi and Ohyama in 1971. A. xylosoxidans is frequently found in aquatic environments. Abdominal, urinary tract, ocular, pneumonia, meningitis, and osteomyelitis are the most common infections. Infective endocarditis is rare. As far as we know, until now, only 19 cases have been described, including this curre...

The locations of cytochrome cd1 nitrite reductases in Pseudomonas aeruginosa and Pseudomonas fluorescens and copper nitrite reductases in Achromobacter cycloclastes and Achromobacter xylosoxidans were identified. Immunogold labeling with colloidal-gold probes showed that the nitrite reductases were synthesized exclusively in anaerobically grown (denitrifying) cells. Little immunogold label occu...

susceptibility testing revealed that the organism was 0. anthropi and that it was susceptible only to trimethoprim-sulfamethoxazole (TMP-SMZ), ciprofloxacin, imipenem, and gentamicin (the typical susceptibility pattern for this organism) [2]. The patient was treated with vancomycin, rifampin, ciprofloxacin, and TMP-SMZ for 6 weeks, followed by ciprofloxacin and TMP-SMZ for 4 1/2 months. Her wou...

A case of community-acquired Achromobacter xylosoxidans bacteremia in a patient with metastatic breast carcinoma is described. The patient's home drinking water was identified as the source of her bacteremia. The case represents the first in which a community-acquired infection due to this organism has been attributed to a documented water source.
