Comparative 16S rRNA gene sequence analysis indicates that two distinct sublineages exist within the genus Alcaligenes: the Alcaligenes faecalis lineage, comprising Alcaligenes aquatilis and A. faecalis (with the three subspecies A. faecalis subsp. faecalis, A. faecalis subsp. parafaecalis and A. faecalis subsp. phenolicus), and the Alcaligenes defragrans lineage, comprising A. defragrans. This...

A chromosomally encoded class D beta-lactamase, OXA-114, was characterized from Achromobacter xylosoxidans strain CIP69598. beta-Lactamase OXA-114 shared 56% amino acid identity with the naturally occurring class D beta-lactamase of Burkholderia cenocepacia and 42% identity with the acquired oxacillinases OXA-9 and OXA-18. OXA-114 has a narrow-spectrum hydrolysis profile, although it includes i...

Pseudomonas alcaligenes, a Gram-negative aerobic bacterium, is a rare opportunistic human pathogen. Here, we report the whole-genome sequence of P. alcaligenes strain MRY13-0052, which was isolated from a bloodstream infection in a medical institution in Japan and is resistant to antimicrobial agents, including broad-spectrum cephalosporins and monobactams.

We report the draft genome sequence of Alcaligenes faecalis strain IITR89, a bacterium able to form indigo by utilizing indole as the sole carbon source. The Alcaligenes species is increasingly reported for biodegradation of diverse toxicants and thus complete sequencing may provide insight into biodegradation capabilities and other phenotypes.

There were 40 cases of Achromobacter xylosoxidans bacteremia during a 6-year period in a medical center in northern Taiwan. Males outnumbered females (72.5% vs 27.5%). Common underlying diseases and conditions in these 40 bacteremic patients were malignancies (57.5%), central venous catheter implants (55%), surgery (35%), neutropenia (30%) and use of steroids (25%). Recurrent bacteremia occurre...

In previous work, only one culture (strain TA12) from a pristine site was reported to utilize the xenobiotic compound p-toluenesulfonate (TSA) as a sole source of carbon and energy for aerobic growth. 'Strain TA12' has now been recognized as a community of three bacteria: Achromobacter xylosoxidans TA12-A, Ensifer adhaerens TA12-B and Pseudomonas nitroreducens TA12-C. Achromobacter xylosoxidans...

We report here the draft genome sequence of Alcaligenes faecalis strain MOR02, a bacterium that is able to colonize nematodes in a temporary fashion and kill insects for their own benefit. The availability of the genome should enable us to explain these phenotypes.

The facultatively anaerobic bacterium Alcaligenes defragrans NKNTAU was found to oxidize taurine (2-aminoethanesulphonate) with nitrate as the terminal electron acceptor. Taurine was transaminated to 2-sulphoacetaldehyde. This was not converted into sulphite and acetate by a "sulphoacetaldehyde sulpho-lyase" (EC 4.4.1.12), but into sulphite and acetyl phosphate, which was identified by three me...

We report a draft genome sequence of Alcaligenes sp. strain HPC1271, which demonstrates antimicrobial activity against multidrug-resistant bacteria. Antibiotic production by Alcaligenes has not been frequently reported, and hence, the availability of the genome sequence should enable us to explore new antibiotic-producing gene clusters.
