Media optimization for the production of cephalosporin C acylase from a novel bacterial source: Alcaligenes xylosoxidans
The remaining cultures revealed the following: left CL, Pseudomonas aeruginosa and Alcaligenes xylosoxidans
; right CL, Pseudomonas aeruginosa; both CL storage cases, Pseudomonas aeruginosa and 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).
PHA depolymerase activities for Alcaligenes xylosoxidans
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
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).
Dialysis-associated Alcaligenes xylosoxidans
peritonitis: a pediatric case.
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).

, and Pseudomonas fluorescens putida group.
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
