| [protective effect of the aerosol immunization of mice with the polycomponent vaccine immunovac vp-4 after the challenge of the animals with klebsiella pneumoniae virulent strain]. | used four schemes of the administration of the preparation with different time of the exposition of the animals in an aerosol chamber were tested with their subsequent intraperitoneal challenge with k. pneumoniae virulent strain k16. irrespective of the number of immunization courses, the administration of the preparation made at intervals of 1 day, or daily, did not ensure any protective effect, but only led to an insignificant increase in their survival time in comparison with nonimmunized ani ... | 2006 | 16532635 |
| clinical and economic impact of bacteremia with extended- spectrum-beta-lactamase-producing enterobacteriaceae. | we studied outcomes of extended-spectrum beta-lactamase (esbl) production in enterobacteriaceae bacteremia. inpatients with bacteremia caused by esbl-producing escherichia coli, klebsiella spp., or proteus spp. (cases) were compared with patients with bacteremia caused by non-esbl producers (controls). outcomes included mortality, mortality due to infection, length of stay (los), delay in appropriate therapy (dat), discharge to a chronic care facility, and hospital cost. ninety-nine cases and 99 ... | 2006 | 16569837 |

| antibiotic susceptibility tests directly on urine samples using uro-quick, a rapid automated system. | during the period june 2003-march 2004, 12,579 urine samples were examined employing the uro-quick system. positive samples (1,948) were subsequently gram-stained and processed by standard procedures for microorganism identification and antibiotic susceptibility determination by the disk diffusion method. results of this latter test were compared with those obtained employing the new rapid uro-quick method. antibiotics were introduced in vials containing 2 ml of mueller-hinton broth, then 0.5 ml ... | 2006 | 16572888 |
| modulation of crystalline proteus mirabilis biofilm development on urinary catheters. | the crystalline biofilms formed by proteus mirabilis can seriously complicate the care of patients undergoing long-term bladder catheterization. the generation of alkaline urine by the bacterial urease causes calcium and magnesium phosphates to precipitate from urine and accumulate in the catheter biofilm, blocking the flow of urine from the bladder. the ph at which these salts crystallize from a urine sample, the nucleation ph (ph(n)), can be elevated by diluting the urine and by increasing its ... | 2006 | 16585633 |

| antibiotic treatment and resistance of unselected uropathogens in the elderly. | a population-based study was conducted among women over the age of 70 years with complaints of uncomplicated urinary tract infections (utis). the positive predictive value of the nitrite test alone or in combination with the leukocyte esterase test ranged between 83% and 99%. the nitrofurantoin prescription rate decreased whereas fluoroquinolone and amoxicillin/clavulanic acid prescriptions increased with increasing age. the aetiology of infection was age-dependent. escherichia coli was the most ... | 2006 | 16473503 |
| functional grouping based on signatures in protein termini. | the two ends of each protein are known as the amino (n-) and carboxyl (c-) termini. short signatures in a protein's termini often carry vital cellular function. no systematic research has been conducted to address the importance of short signatures (3 to 10 amino acids) in protein termini at the proteomic level. specifically, it is unknown whether such signatures are evolutionarily conserved, and if so, whether this conservation confers shared biological functions. current signature detection me ... | 2006 | 16475191 |

| tryptophanase from proteus vulgaris: the conformational rearrangement in the active site, induced by the mutation of tyrosine 72 to phenylalanine, and its mechanistic consequences. | tyr72 is located at the active site of tryptophanase (trpase) from proteus vulgaris. for the wild-type trpase tyr72 might be considered as the general acid catalyst at the stage of elimination of the leaving groups. the replacement of tyr72 by phe leads to a decrease in activity for l-tryptophan by 50,000-fold and to a considerable rearrangement of the active site of trpase. this rearrangement leads to an increase of room around the alpha-c atom of any bound amino acid, such that covalent bindin ... | 2006 | 16455316 |
| isolation of salmonella bacteriophages from swine effluent lagoons. | bacteriophages (phages) associated with salmonella were collected from nine swine manure lagoons in mississippi. phages were isolated by an enrichment protocol or directly from effluent. for enrichment, chloroform-treated samples were filtered (0.22 mum) and selectively enriched by adding a cocktail of salmonella strains in trypticase soy broth. after overnight incubation at 35 degrees c, chloroform was added and samples stored at 5 degrees c. enriched samples were tested by double agar layer (d ... | 2006 | 16455853 |

| crystallization and preliminary x-ray diffraction analysis of a cold-adapted catalase from vibrio salmonicida. | catalase (ec 1.11.1.6) catalyses the breakdown of hydrogen peroxide to water and molecular oxygen. recombinant vibrio salmonicida catalase (vsc) possesses typical cold-adapted features, with higher catalytic efficiency, lower thermal stability and a lower temperature optimum than its mesophilic counterpart from proteus mirabilis. crystals of vsc were produced by the hanging-drop vapour-diffusion method using ammonium sulfate as precipitant. the crystals belong to the monoclinic space group p2(1) ... | 2006 | 16511268 |
| gastric microbiota in elderly patients fed via nasogastric tubes for prolonged periods. | aspiration of oropharyngeal contents is a constant threat for elderly patients fed via a nasogastric tube (ngt). colonization of the oropharynx of these patients by pathological flora and the development of biofilms on the feeding tube has been documented recently. in addition, the presence of the ngt may interfere with the gastro-oesophageal sphincter, leading to gastro-oesophageal reflux. thus, the passage of pathogenic bacteria in both directions is facilitated. the purpose of this study was ... | 2006 | 16516342 |
