During the 19 year period ending December 1984, 4840 strains of Gram-negative non-fermentative bacteria were submitted to the National Collection of Type Cultures for identification. Of these, 195 strains (4.0% of the total) were identified as Pseudomonas cepacia which demonstrates both that the species is regularly encountered in clinical material in the UK and that several laboratories have experienced difficulty in identifying the organism. The sources from which the 195 strains were isolated are reported and also the characteristics by which the species may be recognized. The clinical significance of Ps. cepacia is reviewed, and the resistance of this species to disinfectants and antimicrobial agents commonly used to treat pseudomonas infections is discussed to underline the necessity for the precise identification of Ps. cepacia.

Transfer of several phytopathogenic Pseudomonas species to Acidovorax as Acidovorax avenae subsp. avenae subsp. nov., comb. nov., Acidovorax avenae subsp. citrulli, Acidovorax avenae subsp. cattleyae, and Acidovorax konjaci.
DNA-rRNA hybridizations, DNA-DNA hybridizations, polyacrylamide gel electrophoresis of whole-cell proteins, and a numerical analysis of carbon assimilation tests were carried out to determine the relationships among the phylogenetically misnamed phytopathogenic taxa Pseudomonas avenae, Pseudomonas rubrilineans, "Pseudomonas setariae," Pseudomonas cattleyae, Pseudomonas pseudoalcaligenes subsp. citrulli, and Pseudomonas pseudoalcaligenes subsp. konjaci. These organisms are all members of the family Comamonadaceae, within which they constitute a separate rRNA branch. Only P. pseudoalcaligenes subsp. konjaci is situated on the lower part of this rRNA branch; all of the other taxa cluster very closely around the type strain of P. avenae. When they are compared phenotypically, all of the members of this rRNA branch can be differentiated from each other, and they are, as a group, most closely related to the genus Acidovorax. DNA-DNA hybridization experiments showed that these organisms constitute two genotypic groups. We propose that the generically misnamed phytopathogenic Pseudomonas species should be transferred to the genus Acidovorax as Acidovorax avenae and Acidovorax konjaci. Within Acidovorax avenae we distinguished the following three subspecies: Acidovorax avenae subsp. avenae, Acidovorax avenae subsp. cattleyae, and Acidovorax avenae subsp. citrulli. Emended descriptions of the new taxa are presented.

Taxonomy of Pseudomonas strains isolated from tomato pith necrosis: emended description of Pseudomonas corrugata and proposal of three unnamed fluorescent Pseudomonas genomospecies.
Thirty-three fluorescent Pseudomonas strains isolated from tomato pith necrosis (FPTPN strains) and 89 Pseudomonas corrugata strains were studied by numerical taxonomy. In the dendrogram of distances, the P. corrugata strains constituted a single phenon (phenon 1), whereas 17 of the 33 FPTPN strains clustered in a separate phenon (phenon 2). The other 16 FPTPN strains were included in phena consisting of well-characterized fluorescent Pseudomonas species or were isolated phenotypes. Phena 1 and 2 were distinguished by fluorescence on King B medium, accumulation of poly-beta-hydroxybutyrate, production of levan, and assimilation of sorbitol. DNA-DNA hybridization showed that P. corrugata is a true genomic species (66 to 100% DNA relatedness) and that the FPTPN strains of phenon 2 were divided into three genomic groups. Genomic groups 1 and 2 were not distinct from each other phenotypically, and genomic group 3 could be distinguished from genomic groups 1 and 2 only on the basis of assimilation of citraconate and laevulinate. Genomic groups 1 and 2 are related to P. corrugata (40 to 55% DNA relatedness), whereas genomic group 3 is less closely related to P. corrugata (20 to 23% DNA relatedness). The lipopolysaccharide patterns on electrophoresis gels and fatty acid profiles of strains belonging to genomic group 1 through 3 are different from each other and from the lipopolysaccharide patterns and fatty acid profiles of P. corrugata. However, cross-reactions were observed between P. corrugata and the FPTPN strain genomic groups, indicating that there are common epitopes of the lipopolysaccharides. The three FPTPN strain genomic groups were not named as species but were designated Pseudomonas genomospecies FP1, FP2, and FP3.

Pseudomonas oryzihabitans is an uncommon pathogen that may cause catheter-associated infections, particularly in immunocompromised patients. Although it has been isolated from environment, the source of human infection is not well documented. In the present study, 14 isolates of P. oryzihabitans were recovered over a 28-month period from a karstified chalk aquifer, allowing to advance that distributed natural water could be a source of contamination. Microbiological analyses showed that the bacterium was mainly associated with suspended particulate matters. To investigate the clonality of P. oryzihabitans environmental isolates, 16S rRNA gene sequencing, antibiogram and randomly amplified polymorphic DNA (RAPD) typings were performed. Results demonstrated (i) the presence of at least three clones within the aquifer and (ii) that the presence of the bacterium in groundwater is not only the result of a biofilm bloom but also of an exogenous contamination.
