Achromobacter xylosoxidans, a Pseudomonaslike bacterium, contaminated a boar stud laboratory’s water distillation and delivery system that was used for extension of raw semen for artificial insemination. In sow herds that used the contaminated semen, conception rates decreased and vulvar discharges, culled sows, and nonproductive sow days increased. Thorough diagnostic testing revealed that A x...
Copper-containing nitrite reductases possess a trimeric structure where the catalytic Cu site, located at the monomer-monomer interface, resembles the catalytic sites of a number of Zn enzymes. Nitrite reductase from Alcaligenes xylosoxidans has optimum activity at pH 5.2 which decreases to a negligible level at pH 8. The structure of this nitrite reductase has previously been determined at pH ...
RATIONALE Achromobacter xylosoxidans infection is mostly reported in immunocompromised patients. Until now, it is still rarely reported in patients undergoing peritoneal dialysis. PATIENT CONCERNS This is the 1st case of A xylosoxidans infection due to tunnel infection of a Tenckhoff catheter. DIAGNOSIS The diagnosis was confirmed by the report of culture. INTERVENTIONS Risk factors for t...
Achromobacter xylosoxidans is an environmental opportunistic pathogen, which infects an increasing number of immunocompromised patients. In this study we combined genomic analysis of a clinical isolated A. xylosoxidans strain with phenotypic investigations of its important pathogenic features. We present a complete assembly of the genome of A. xylosoxidans NH44784-1996, an isolate from a cystic...
Both the enantiomers of 2,3-dihydro-1,4-benzodioxin-2-carboxylic acid are valuable chiral synthons for enantiospecific synthesis of therapeutic agents such as (S)-doxazosin mesylate, WB 4101, MKC 242, 2,3-dihydro-2-hydroxymethyl-1,4-benzodioxin, and N-[2,4-oxo-1,3-thiazolidin-3-yl]-2,3-dihydro-1,4-benzodioxin-2-carboxamide. Pharmaceutical applications require these enantiomers in optically pure...
Abstract Diversity of the functional genes encoding dissimilatory nitrite reductase was investigated for the first time in denitrifying halobenzoate degrading bacteria and in two 4-chlorobenzoate degrading denitrifying consortia. Nitrite reductase genes were PCR-amplified with degenerate primers (specific to the two different types of respiratory nitrite reductase, nirS and nirK), cloned and se...
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...
The nitrite reductase (NIR) and blue copper protein (BCP) genes have been cloned from Achromobacter cycloclastes and characterized. NIR gene encodes a protein of 378 amino acid residues including a putative signal peptide of 37 residues. BCP gene encodes a protein of 148 residues with a 24-residue signal peptide. The DNA-derived amino acid sequence of NIR is in complete agreement with that from...
