The remaining isolates were closely related to Methylobacterium extorquens, Bosea vestrii, and Achromobacter xylosoxidans

Strain AYS3 showed 100% similarity with Achromobacter xylosoxidans
and found to be closely related to Achromobater denitrificans by phylogenetic analysis.

aeruginosa, Stenotrophomonas maltophilia, Achromobacter xylosoxidans
and Staphylococcus aureus in the presence of factors that mimic the physiological environment of the CF lung.
The most common respiratory pathogens in CF are Staphylococcus aureus and Pseudomonas aeruginosa, but new pathogens are evolving, such as nontuberculous mycobacteria (NTM), Stenotrophomonas maltophilia, Burkholderia cepacia, and Achromobacter xylosoxidans
TMB-1 was reported in 2012 in an Achromobacter xylosoxidans
isolate from a hospital in Tripoli, Libya (8); TMB-2 was later reported in Japan (9).
Unlike many cystic fibrosis patients, she did not have a history of chronic Pseudomonas aeruginosa infections, but Stenotrophomonas maltophilia and Achromobacter xylosoxidans
had been previously isolated from her sputum.
Several 16S rRNA gene sequences of type strains from the genus Bordetella were retrieved from GenBank, and a phylogenetic tree was constructed by using a neighbor-joining algorithm with Achromobacter xylosoxidans
xylosoxidans as the out-group (Figure).
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).
Multidrug-resistant Achromobacter xylosoxidans
was recovered from the sputum of a patient with cystic fibrosis.
