| the specificity of bacterial siderophore receptors probed by bioassays. | the ability to utilize siderophores of bacterial and fungal origin has been studied in wild-type and mutant strains of the enterobacterial genera salmonella, escherichia, shigella, moellerella, klebsiella, enterobacter, hafnia, pantoea, ewingella, tatumella, yersinia, and in the non-enterics aeromonas, pseudomonas and aureobacterium. although only a few representative strains were tested, the results show characteristic genus-specific differences in the utilization of hydroxamate and catecholate ... | 1991 | 1663779 |
| isolation of ewingella americana from a patient with conjunctivitis. | ewingella americana (family enterobacteriaceae) was isolated separately from both eyes of a 30-year-old woman. clinical signs and symptoms included adhesive eyelids, itching and edematous upper and lower lids. therapy with amoxicillin-clavulanate resulted in the relief of symptoms. ewingella americana can be isolated worldwide, but seems to be a rare pathogen. | 1991 | 1794367 |
| plasmids as epidemiologic markers in nosocomial gram-negative bacilli: experience at a university and review of the literature. | bacterial plasmids have become valuable markers for the comparison of strains of nosocomial gram-negative bacilli. the importance of plasmids in nosocomial infections is primarily due to their transferable antibiotic resistance genes (r plasmids), but other plasmid-mediated traits may eventually serve as potential markers. stable cryptic plasmids have also served to relate outbreak strains, particularly nonfermenting strains of gram-negative bacteria. klebsiella pneumoniae and serratia marcescen ... | 1986 | 3538313 |
| wound colonization by ewingella americana. | ewingella americana was recovered from a wound on the left leg of a 46-year-old male after a compound fracture of the tibia and fibula. compared with the reported characteristics of 44 american strains, this strain was shown to belong to biogroup 1. the isolation of this bacterium in south africa confirms its wide geographical distribution in clinical specimens. colonization was not associated with clinical deterioration. | 1986 | 3958154 |
| mechanism of cross-contamination of blood culture bottles in outbreaks of pseudobacteremia associated with nonsterile blood collection tubes. | several studies have identified nonsterile blood collection tubes as the reservoir for contaminating microorganisms in outbreaks of pseudobacteremia. microorganisms are thought to be transferred from the nonsterile tubes to the blood culture tubes when blood is drawn for cultures, but the validity of this hypothesis has not previously been tested. we recently investigated an outbreak of ewingella americana pseudobacteremia in which an epidemiological association was found between pseudobacteremi ... | 1985 | 4019740 |
| ewingella americana gen.nov., sp.nov., a new enterobacteriaceae isolated from clinical specimens. | we propose the name ewingella gen.nov. for a new group in the enterobacteriaceae. ewingella is phenotypically distinct from all other groups of enterobacteriaceae. the members of this genus are lipase- and deoxyribonuclease-negative; voges-proskauer-positive; lysine-, ornithine- and arginine-decarboxylase-negative; anaerogenic; they produce acid from glucose in the presence (and absence) of iodoacetate, but fail to produce acid from l-arabinose, melibiose, raffinose, d-sorbitol or sucrose. dna-r ... | 1983 | 6847036 |
| isolation of ewingella americana from mollusks. | twenty-three of 2446 strains of enterobacteriaceae isolated from mollusks were identified as ewingella americana both biochemically and by dna hybridization with strain s6/1111. the biochemical characteristics of the new strains showed few differences from previously reported strains obtained from human clinical specimens. these are the first strains of e. americana isolated from animals. | 1995 | 7580799 |

| isolation, selection and characterization of root-associated growth promoting bacteria in brazil pine (araucaria angustifolia). | araucaria angustifolia, a unique species of this genus that occurs naturally in brazil, has a high socio-economic and environmental value and is critically endangered of extinction, since it has been submitted to intense predatory exploitation during the last century. root-associated bacteria from a. angustifolia were isolated, selected and characterized for their biotechnological potential of growth promotion and biocontrol of plant pathogenic fungi. ninety-seven strains were isolated and subje ... | 2011 | 21596540 |
| prevalence of ewingella americana in retail fresh cultivated mushrooms (agaricus bisporus, lentinula edodes and pleurotus ostreatus) in zaragoza (spain). | the prevalence and mycopathogenic potential of enterobacteriaceae (especially ewingella americana) in cultivated mushrooms were studied. a total of 95 samples of agaricus bisporus, lentinula edodes and pleurotus ostreatus were analyzed to quantify the enterobacteriaceae and to identify the species isolated. the host pathogenicity test was used to verify their mycopathogenic potential. the genus pseudomonas was also quantified, since it is the predominant bacterial group in cultivated mushrooms. ... | 2004 | 19712317 |
| enterobacteriaceae facilitate the anaerobic degradation of glucose by a forest soil. | anoxic micro zones that occur in soil aggregates of oxic soils may be temporarily extended after rainfall and thus facilitate the anaerobic degradation of organic compounds in soils. the microbial degradation of glucose by anoxic slurries of a forest soil yielded acetate, co2, h2, succinate, and ethanol, products indicative of mixed acid fermentation. prokaryotes involved in this process were identified by time-resolved 16s rrna gene-targeted stable isotope probing with [13c-u]-glucose. all labe ... | 2009 | 19453494 |
