More than 90 morphological and physiological characters of 227 strains of pseudomonads isolated from clinical specimens and 16 reference strains are described. The clinical isolates included P. aeruginosa (apyocyanogenic), P. fluorescens, P. putida, P. pseudomallei, P. cepacia, P. acidovorans, P. alcaligenes, P. pseudoalcaligenes, P. stutzeri, P. putrefaciens, P. maltophilia, and P. diminuta.
Pseudomonas fluorescens strains that produce the polyketide antibiotic 2,4-diacetylphloroglucinol (2,4-DAPG) are among the most effective rhizobacteria that suppress root and crown rots, wilts, and damping-off diseases of a variety of crops, and they play a key role in the natural suppressiveness of some soils to certain soilborne pathogens. Root colonization by 2,4-DAPG-producing P. fluorescen...
A real-time PCR SYBR green assay was developed to quantify populations of 2,4-diacetylphloroglucinol (2,4-DAPG)-producing (phlD+) strains of Pseudomonas fluorescens in soil and the rhizosphere. Primers were designed and PCR conditions were optimized to specifically amplify the phlD gene from four different genotypes of phlD+ P. fluorescens. Using purified genomic DNA and genomic DNA extracted f...
BACKGROUND Pharmaceutical compounding, the manipulation of ingredients to create a customized medication, is a widespread practice. In January 2005, the Centers for Disease Control and Prevention was notified of 4 cases of Pseudomonas fluorescens bacteremia that were traced to contaminated heparinized saline intravenous flush syringes prepared as a compounded medical product. PATIENTS AND MET...
Cabai rawit (Capsicum frutescens L.) merupakan salah satu tanaman hortikultura yang bernilai ekonomi tinggi. Produksi cabai seringkali terkendala oleh penyakit layu batang diakibatkan cendawan Fusarium sp. Penelitian ini bertujuan untuk mengetahui pengaruh konsorsium bakteri Bacillus spp. dan Pseudomonas fluorescens sebagai agensia hayati pengendali fusarium pada rawit. dilaksanakan di screenho...
Plants have the ability to acquire an enhanced level of resistance to pathogen attack after being exposed to specific biotic stimuli. In Arabidopsis, nonpathogenic, root-colonizing Pseudomonas fluorescens bacteria trigger an induced systemic resistance (ISR) response against infection by the bacterial leaf pathogen P. syringae pv tomato. In contrast to classic, pathogen-induced systemic acquire...
in this research psedomonas fluorescens as a probiotic, sodium chloride, plant extract (terminalia catappa), malachite green and formalin as antifungal agents were used daily for 19 days on rainbow trout fertilized eggs in order to compare their survival with untreated fertilized eggs in control group. results showed that the percent of live eggs (eyed) after 19 days treatment with p. fluoresce...
FpvA, the ferripyoverdine outer membrane receptor of Pseudomonas aeruginosa ATCC 15692 (PAO1 strain), is not specific to the pyoverdine produced by PAO1, but is also able to recognize the structurally different (ferri)pyoverdine of P. fluorescens ATCC 13525. The specificity of FpvA was assessed by iron uptake competitions using the wild-type strains P. aeruginosa ATCC 15692 and P. fluorescens A...
Twenty-nine strains of Pseudomonas, classified as P. fluorescens biotype D or E or as P. multivorans, were examined for the production of pyrrolnitrin, an antifungal agent synthesized in P. aureofaciens. Eight strains were shown to produce pyrrolnitrin in shake-flask fermentation. Four cultures were from the multivorans taxon, and the remaining four were members of the fluorescens group. The an...
