Alcaligenes xylosoxidans

a bacterial species isolated from blood, cerebrospinal fluid, bronchial washings, urine, pus, and wounds. The subspecies subsp. xylosoxidans colonizes patients with cystic fibrosis and entubated patients.

Alcaligenes xylosoxidans

An aerobic, motile, oxidase and catalase positive, nonfermentative gram-negative environmental bacillus which colonises moist areas in hospitals and the GI and respiratory tracts of patients with cystic fibrosis.
Mode of transmission Contaminated fluids (e.g., IV, haemodialysis, irrigation, disinfectants).
Clinical findings Bacteraemia, urinary tract infections, meningitis, wound infections, upper respiratory infections, occurring in immune compromised hosts, or in nosocomial outbreaks.

Alcaligenes xylosoxidans

A species that does not ferment glucose. It has been implicated rarely in lung infections in patients with cystic fibrosis and in other health care associated infections in patients with immunosuppressing or malignant illnesses. Synonym: Achromobacter xylosoxidans

Alcaligenes xylosoxidans, also known as Achromobacter xylosoxidans, is a gram-negative, water-borne organism that causes healthcare-associated infections (1-7) and bacteremia in immunocompromised patients with indwelling catheters (6-11); it can also contaminate liquids (2,5,12-14).

Other gram-negative rods that may be found in sputum of CF patients include Burkholderia cepacia, Alcaligenes xylosoxidans, Stenotrophomonas maltophilia, and methicillin-resistant Staphylococcus aureus (MRSA) (Beringer & Appleman, 2000).
The multidrug-resistant pathogen was Acinetobacter baumannii in 55% of cases, Pseudomonas aeruginosa in 37%, Klebsiella pneumoniae in 5%, and Alcaligenes xylosoxidans in 3%.
Two isolates, Alcaligenes xylosoxidans and Pseudomonas aeruginosa, were found at all twelve locations and in a very high percentage of the samples collected (72% and 92% of the 36 samples respectively).
Pseudomonas auriginosa and Alcaligenes xylosoxidans were isolated from the patient's conjunctiva, cornea, contact lens storage case and lens solution, and polymerase chain reaction analysis of corneal scrapings was positive for Acanthameoba (see pages 83-86).

The dramatic improvement in the survival of patients with cystic fibrosis (CF) has been complicated by the development of highly resistant strains of Pseudomonas aeruginosa and Staphylococcus aureus; the appearance of new virulent pathogens, such as Burkholderia cepacia; and the emergence of organisms of undetermined clinical importance, such as Alcaligenes xylosoxidans, Stenotrophomonas maltophilia, and the nontuberculous mycobacteria (NTM) (1-4).
Later on Pseudomonas aeruginosa (PA) and other gram-negative non-fermenting organisms, such as Stenotrophomonas maltophilia, members of the Burkholderia cepacia-complex, and Alcaligenes xylosoxidans prevail.
