13. Identification of Achromobacter species by cellular fatty acids and by production of keto acids.
The cellular fatty acid composition and metabolic products of 12 reference strains of Achromobacter sp. and A. xylosoxidans were determined by gas-liquid chromatography (GLC). Results showed that the two Achromobacter groups are strikingly different and can be readily distinguished on the basis of cellular fatty acids and the short-chain acids produced by Ac

14. Achromobacter xylosoxidans (Alcaligenes xylosoxidans subsp. xylosoxidans) bacteremia associated with a well-water source: case report and review of the literature.
A case of community-acquired Achromobacter xylosoxidans bacteremia in a patient with metastatic breast carcinoma is described. The patient's home drinking water was identified as the source of her bacteremia. The case represents the first in which a community-acquired infection due to this organism has been attributed to a documented water source.

15. Neonatal meningitis caused by Achromobacter xylosoxidans.
The clinical and bacteriological findings in a case of neonatal meningitis caused by Achromobacter xylosoxidans are presented. This appears to be only the second report of meningitis caused by this species.

16. Corneal ulcer due to Achromobacter xylosoxidans.
We report a case of corneal ulcer caused by the opportunistic organism Achromobacter xylosoxidans which developed during chronic topical steroid treatment of an eye with neovascular glaucoma. A. xylosoxidans has probably been underreported as a cause of ocular infection because of confusion between this organism and other Gram-negative organisms, particularl

17. Achromobacter xylosoxidans isolates in Hawaii.
Clinical and bacteriological features of nine cases in which Achromobacter xylosoxidans were isolated in Hawaii are described. Five cases were ear infections mixed with other gram-negative bacteria. Colonial morphology, xylose oxidation, peritrichous flagella staining, and antibiotic susceptibility pattern assisted in separating this bacterium from other non

18. NreB from Achromobacter xylosoxidans 31A Is a Nickel-Induced Transporter Conferring Nickel Resistance
There are two distinct nickel resistance loci on plasmid pTOM9 from Achromobacter xylosoxidans 31A, ncc and nre. Expression of the nreB gene was specifically induced by nickel and conferred nickel resistance on both A. xylosoxidans 31A and Escherichia coli. E. coli cells expressing nreB showed reduced accumulation of Ni2+, suggesting that NreB mediated nicke

19. Ribosomal DNA-Directed PCR for Identification of Achromobacter (Alcaligenes) xylosoxidans Recovered from Sputum Samples from Cystic Fibrosis Patients
The opportunistic human pathogen Achromobacter (Alcaligenes) xylosoxidans has been recovered with increasing frequency from respiratory tract culture of persons with cystic fibrosis (CF). However, confusion of this species with other closely related respiratory pathogens has limited studies to better elucidate its epidemiology, natural history, and pathogeni

20. Strains of Achromobacter xylosoxidans from clinical material.
Eleven strains of Achromobacter xylosoxidans have been received from among 1106 strains of Gram-negative, non-fermentative bacteria submitted to the National Collection of Type Cultures for computer-assisted identification since 1 January 1972. The strains showed resistance to a wide range of antimicrobial agents and five of the isolates possibly played a pa

21. Nosocomial colonization and infection by Achromobacter xylosoxidans.
Achromobacter xylosoxidans, a bacterial species named in 1971, is often isolated from aqueous environments, but little has been reported about its pathogenicity in humans, its epidemiological pattern, and its susceptibility to antibiotics and antiseptics. We were faced with an epidemic caused by this microorganism for 18 months in an intensive care unit. Two

22. Use of Random Amplified Polymorphic DNA PCR To Examine Epidemiology of Stenotrophomonas maltophilia and Achromobacter (Alcaligenes) xylosoxidans from Patients with Cystic Fibrosis
Stenotrophomonas maltophilia and Achromobacter (Alcaligenes) xylosoxidans have been increasingly recognized as a cause of respiratory tract colonization in cystic fibrosis (CF). Although both organisms have been associated with progressive deterioration of pulmonary function, demonstration of causality is lacking. To examine the molecular epidemiology of S.

23. Serological classification of Achromobacter xylosoxidans.
Adult rabbits were immunized with nine Achromobacter xylosoxidans strains by intravenous injection of Formalin-killed organisms. Antisera thus obtained were reciprocally titrated with the nine A. xylosoxidans strains, and seven sera were defined as serologically distinct. Three of nine antisera possessed one common antibody while also each having their own s

24. Diversity of plasmids in Achromobacter xylosoxidans isolates responsible for a seemingly common-source nosocomial outbreak.
Achromobacter xylosoxidans, an uncommon yet highly resistant opportunistic pathogen, was isolated from nine hospitalized patients during an 8-month period. It had been isolated from only seven patients with either nonfatal infection or colonization from 1981 to 1984. From June 1985 to January 1986, A. xylosoxidans was isolated 18 times from seven different s
