| growth control of small-colony variants by genetic regulation of the hemin uptake system. | small-colony variants (scvs) are slow-growing variants of human bacterial pathogens. they are associated with chronic persistent infections, and their biochemical identification and antimicrobial treatment are impaired by altered metabolic properties. to contribute to the understanding of scv-mediated infections, we analyzed a clinical scv isolate derived from a chronic prosthetic hip infection. a sequence analysis of housekeeping genes identified an enterobacter hormaechei-like organism. the sc ... | 2004 | 15039350 |
| isolates of the enterobacter cloacae complex induce apoptosis of human intestinal epithelial cells. | strains of the enterobacter cloacae complex are becoming increasingly important human pathogen. the aim of the study was to identify, by sequencing the hsp60 gene, the species of clinical isolates phenotypically identified as e. cloacae and to examine them for virulence-associated properties: the ability of adhesion, invasion to hep-2 cells and the induced apoptosis of infected epithelial cells. the majority of the strains were identified as enterobacter hormaechei with e. hormaechei subsp. stei ... | 2010 | 20451600 |
| resistance patterns and integron cassette arrays of enterobacter cloacae complex strains of human origin. | the aim of this research was to analyse the resistance patterns and characterize the distribution and genetic content of resistance integrons within enterobacter cloacae complex strains originating from hospitalized patients. the strains were included in the e. cloacae complex study following sequence analysis of the hsp60 gene. the determination of resistance towards eight classes of antimicrobials was followed by pcr detection of integrons and analyses of the size and sequences of their variab ... | 2011 | 21330416 |
| high incidence of plant growth-stimulating bacteria associated with the rhizosphere of wheat grown on salinated soil in uzbekistan. | soil salinization is increasing steadily in many parts of the world and causes major problems for plant productivity. under these stress conditions, root-associated beneficial bacteria can help improve plant growth and nutrition. in this study, salt-tolerant bacteria from the rhizosphere of uzbek wheat with potentially beneficial traits were isolated and characterized. eight strains which initially positively affect the growth of wheat plants in vitro were investigated in detail. all eight strai ... | 2008 | 18211262 |
