| structural and pathogenic properties of aeromonas schubertii. | we investigated the phenotypic, structural, and pathogenic properties of 11 aeromonas schubertii strains recovered from extraintestinal sites. most a. schubertii strains were autoagglutination positive, possessed a high surface charge but low hydrophobicity, and fell into one or two biogroups on the basis of carbon substrate utilization patterns. fatty acid methyl ester analysis of a. schubertii revealed this species to contain a relatively high percentage of branched fatty acids (i-13:0, i-15:0 ... | 1992 | 1563798 |
| gas-liquid chromatographic analysis of cellular fatty acid methyl esters in aeromonas species. | the cellular fatty acids of 39 strains belonging to the genus aeromonas (aeromonas hydrophila, aeromonas caviae, aeromonas sobria, aeromonas media, aeromonas schubertii, aeromonas veronii) were determined by high resolution gas-liquid chromatography. the fatty acid profiles were characterized by major amounts (60% or more) of one saturated (hexadecanoic acid = 16:0) and two unsaturated (hexadecenoic acid = 16:1 and octadecenoic acid = 18:1) acids. while the majority of the strains of the six spe ... | 1991 | 1930556 |
| characterization of aeromonas schubertii strains recently isolated from traumatic wound infections. | recent studies have resulted in the proposal of a new species, aeromonas schubertii (mannitol, sucrose, and indole negative), formerly termed enteric group 501, on the basis of the study of seven strains isolated from the southeastern and southwestern united states and puerto rico. we have isolated two phenotypically similar a. schubertii strains from infected human wounds sustained in the chesapeake bay area. their identification was confirmed by dna-dna hybridization to the centers for disease ... | 1989 | 2768470 |
| aeromonas schubertii, a new mannitol-negative species found in human clinical specimens. | in 1983 the vernacular name enteric group 501 was coined for a group of strains that had been referred to our laboratory as "possible vibrio damsela that does not require nacl for growth." by dna-dna hybridization (hydroxyapatite method, 32p, 60 and 75 degrees c), six strains of enteric group 501 were closely related to the labeled strain 2446-81 (70 to 95% at 60 degrees c and 71 to 93% at 75 degrees c; 0 to 1% divergence). type strains of all aeromonas species and reference strains of six other ... | 1988 | 3139706 |
| dna relatedness among aeromonas allosaccharophila strains and dna hybridization groups of the genus aeromonas. | the genomic relatedness among three aeromonas allosaccharophila strains, including the type strain, and other aeromonas type and reference strains that were assigned to dna hybridization groups was estimated by dna-dna hybridization (competition procedure using a membrane method). all a. allosaccharophila strains were highly related (70 to 100%) to strains 289t (= cect 4199t) and atcc 35942. type strains of other validated aeromonas species, reference strains of dna groups 8 and 11, and the aero ... | 1995 | 7727276 |
| identification of aeromonas schubertii and aeromonas jandaei by using a polymerase chain reaction-probe test. | two oligonucleotide primers were used in a polymerase chain reaction-protocol to amplify a region (approx. 850 bp) of the 16s rrna gene of aeromonas schubertii and aeromonas jandaei. hybridization of the polymerase chain reaction products to specific internal probes provided a highly specific method for the identification of these two species. | 1993 | 8486241 |
| misidentification of unusual aeromonas species as members of the genus vibrio: a continuing problem. | two unusual cases of aeromonas infection are described, one associated with bacteremia (aeromonas schubertii) and another in which the organism was recovered from an infected gall bladder (aeromonas veronii biotype veronii). these strains were initially identified as vibrio damsela and vibrio cholerae by the vitek and api 20e systems, respectively. use of appropriate screening tests and familiarity with the newer aeromonas species could prevent initial misidentifications and potential public hea ... | 1998 | 9542946 |
| phylogenetic positions of aeromonas encheleia, aeromonas popoffii, aeromonas dna hybridization group 11 and aeromonas group 501. | the 16s rdna sequences of the recently described aeromonas encheleia and aeromonas popoffii, were determined and compared with data from all known aeromonas sp. diagnostic 16s rdna regions were also sequenced for some strains previously considered as an extension of a. encheleia and a strain of aeromonas group 501 (formerly enteric group 501). results indicated that a. encheleia and a. popoffii are phylogenetically separated species as originally described. a conclusion about hg11 taxonomic stat ... | 1999 | 10555319 |
| interaction of cefotetan and the metallo-beta-lactamases produced in aeromonas spp. and in vitro activity. | aeromonas spp. are increasingly being recognized as human pathogens. the presence of metallo-beta-lactamases in these organisms represents a potential problem in antimicrobial therapy. mechanism-based inactivators of beta-lactamases are used to overcome the resistance of clinical pathogens to beta-lactam antibiotics, but no clinical useful inhibitors of the metallo-beta-lactamases are presently known. studying the interaction between cefotetan and aeromonas spp. producing metallo-beta-lactamase ... | 2000 | 10765032 |
| mesophilic aeromonads in wild and aquacultured freshwater fish. | numbers and species of motile aeromonas were determined in freshly caught freshwater fish, in the surrounding environment, and also during iced chilled storage of fish specimens. although no significant differences were observed in water samples, initial levels for skin, gill, and intestines were significantly lower in farmed rainbow trout (oncorhynchus mykiss) than in wild brown trout (salmo trutta) and pike (esox lucius). during storage of wild specimens, naturally occurring aeromonads grew fa ... | 2001 | 11348001 |
