| epidemiology of extended spectrum beta-lactamases. | beta-lactamases play a major part in resistance, as recently redemonstrated by the emergence of extended spectrum beta-lactamases. since its discovery in fr germany, shv-2 has been reported from four continents and ctx-1 (tem-3) was established in at least 26 french hospitals. more than 12 other enzymes have been individualized. the newest aspect of resistance was probably underestimated because most strains of enterobacteria (mainly klebsiella pneumoniae) appeared susceptible to oxyimino-beta-l ... | 1989 | 2689354 |

| an improved broth-microdilution procedure for testing metal ion resistance of klebsiella pneumoniae. | a new broth-microdilution method for testing metal ion resistance was designed in order to circumvent the formation of insoluble complexes between cations and compounds of the test medium. high-level cefotaxime resistant k. pneumoniae isolates tested by this procedure proved to be susceptible to cd, hg and zn but resistant to pb, mo and w. the metal ion resistance was not linked to the beta-lactam resistance gene. | 1989 | 2690846 |
| evidence for a chromosomally determined bacteriocin production by klebsiella pneumoniae. | location of the genes responsible for pneumocin production in klebsiella pneumoniae was examined by classical procedures. conjugal intrageneric transfers, elimination experiments with various curing agents, high temperature and plasmid isolation procedures showed that this strain did not harbour any plasmid. hence chromosomal location of the genetic determinants is suggested. | 1989 | 2691362 |

| biochemical, immunological and physicochemical comparisons between ohio-1 and four shv-type beta-lactamases. | the biochemical, immunological and physicochemical properties of the beta-lactamase ohio-1 were compared to those of four beta-lactamases commonly found in klebsiella pneumoniae: shv-1, shv-3 and the beta-lactamases of strains gn 11-03 and gn 422. the substrate profile of shv-1, ohio-1 and of the beta-lactamases gn 11-03 and gn 422 were similar, while that of shv-3 appeared comparable to that of the extended spectrum shv-2. moreover, anti-tem-1 serum inactivated ohio-1 as well as shv-1 and the b ... | 1989 | 2693199 |
| klebsiella pneumoniae haemolysin adsorption to red blood cells. | it was necessary to incubate the klebsiella pneumoniae haemolysin with erythrocytes at 37 degrees c to produce the whole lytic action. the amount of attached klebolysin at 4 degrees c increased as its concentration in the medium increased, until the erythrocyte surface was saturated. treatment with 2-mercaptoethanol was necessary to permit the adsorption; it was inhibited by low concentrations of cholesterol. klebsolysin was immunogenic and its antiserum neutralized its own haemolytic effect and ... | 1989 | 2693425 |
| comparative study of five plasmid-mediated ceftazidimases isolated in klebsiella pneumoniae. | five plasmid-mediated beta-lactamases conferring a high level of resistance to ceftazidime were isolated from klebsiella pneumoniae strains. these ceftazidimases (caz) differed in their isoelectric point (from 5.3 to 8.2) and were encoded by large self-transferable plasmids of 85 kb (caz-2, caz-3) or greater than or equal to 150 kb (caz-1, caz-4, caz-5). the 85 kb plasmids seemed closely related to pcff04 encoding ctx-1 enzyme and belonged to the same incompatibility group 7 or m. these beta-lac ... | 1989 | 2693430 |

| regulation of gene expression and cellular localization of cloned klebsiella aerogenes (k. pneumoniae) urease. | the genes for klebsiella aerogenes (k. pneumoniae) urease were cloned and the protein was overexpressed (up to 18% of total protein consisted of this enzyme) in several hosts. the small size of the dna encoding urease (3.5 kb), the restriction map, and the regulation of enzyme expression directed by the recombinant plasmid are distinct from other cloned ureases. nickel concentration did not affect urease gene expression, as demonstrated by the high levels of apoenzyme measured in cells grown in ... | 1989 | 2693604 |
| [respiratory infectious complications in patients with lung cancer]. | since respiratory infectious complications in lung cancer cases are major obstacles for adequate or intensive anticancer chemotherapy, they often affect prognosis unfavorably. such respiratory infections secondary to lung cancer generally occur on the basis of defects of the defence mechanism against infections due to disturbance in the clearance system in sites peripheral to bronchial obstruction or stenosis. the lowered concentration of antimicrobial agents at the site of infection, resulting ... | 1989 | 2693782 |
| positive control of colanic acid synthesis in escherichia coli by rmpa and rmpb, two virulence-plasmid genes of klebsiella pneumoniae. | in klebsiella pneumoniae, the mucoid phenotype, which is a virulence factor, is distinct from capsule production. it is positively controlled by a plasmid gene, designated rmpa. when introduced into certain escherichia coli strains, rmpa induces expression of a mucoid phenotype, which results from overproduction of colanic acid at 30 degrees c but not at 37 degrees c. in e. coli, production of colanic acid is regulated by three genes: rcsa and rcsb which act as positive regulators, and rcsc whic ... | 1989 | 2693894 |
| analysis of the nag regulon from escherichia coli k12 and klebsiella pneumoniae and of its regulation. | four genes, nagr, a, b and e, clustered in the nag locus of escherichia coli k12 and klebsiella pneumoniae, were cloned and physically mapped, and the corresponding gene products involved in amino sugar metabolism identified. expression of the nag genes was also analysed using a series of lacz fusions. in both bacteria, the genes are arranged in two divergent operons and controlled by a common nagr repressor. the corresponding gene nagr was found to map in the first operon together with the prom ... | 1989 | 2693951 |
| molecular characterization of the gene encoding shv-3 beta-lactamase responsible for transferable cefotaxime resistance in clinical isolates of klebsiella pneumoniae. | in klebsiella pneumoniae 86-4, cefotaxime resistance was due to a transferable broad-spectrum beta-lactamase, shv-3. the plasmid-borne gene encoding shv-3 has been cloned, and the primary structure of the enzyme was deduced from its nucleotide sequence. shv-3 differs from shv-1 in two positions. the extended substrate profile of shv-3 probably results from the substitution of ser-213 for gly, as in shv-2, whereas replacement of arg-180 by leu resulted in a decrease in the pi from 7.6 to 7.0. the ... | 1989 | 2694951 |
| a transient-kinetic study of the nitrogenase of klebsiella pneumoniae by stopped-flow calorimetry. comparison with the myosin atpase. | the pre-steady-state kinetics of mgatp hydrolysis by nitrogenase from klebsiella pneumoniae were studied by stopped-flow calorimetry at 6 degrees c and at ph 7.0. an endothermic reaction (delta hobs. = +36 kj.mol of atp-1; kobs. = 9.4 s-1) in which 0.5 proton.mol of atp-1 was released, has been assigned to the on-enzyme cleavage of mgatp to yield bound mgadp + pi. the assignment is based on the similarity of these parameters to those of the corresponding reaction that occurs with rabbit muscle m ... | 1989 | 2695063 |

| aminoglycoside resistance patterns in clinical isolates of e. coli and klebsiella sp. from czechoslovakia and the united states. | resistance of gram-negative bacilli to aminoglycoside antibiotics differs by region and country. previous studies have demonstrated predominance of the nucleotidyltransferase anl(2") as the mechanism of enzymatic resistance to gentamicin in the united states and many european countries (federal republic of germany, switzerland, greece, turkey) whereas the acetylating enzymes aac(6') and aac(3) were the principal causes of resistance to aminoglycosides in japan and chile. in the present compariso ... | 1989 | 2696761 |
