| [molecular mechanisms of cephalosporin resistance in gram-negative bacteria of the enterobacteriaceae family]. | extended spectrum beta lactamase genes were detected by the pcr in 87.6% of 231 enterobacteriaceae strains isolated in medical institutions of moscow, st. petersburg, tomsk and nazran that showed a decrease in their susceptibility to 3rd generation cephalosporins. alone or in various combinations tem type beta lactamases were detected in 43.3% of the isolates, 46.8 and 51.2% of the isolates produced shv type and ctx type beta lactamases respectively. combinations of 2 and 3 different determinant ... | 2004 | 15344391 |
| the spread of bla oxa-48 and bla oxa-244 carbapenemase genes among klebsiella pneumoniae, proteus mirabilis and enterobacter spp. isolated in moscow, russia. | the spread of carbapenemase-producing enterobacteriaceae (cpe) is a great problem of healthcare worldwide. study of the spread for bla oxa-48-like genes coding epidemically significant carbapenemases among hospital pathogens is important for the regional and global epidemiology of antimicrobial resistance. | 2015 | 26526183 |
| [etiopathogenetic approach to the treatment of viral-bacterial pneumonias]. | the efficacy of aerosols of leukocytal interferon used in complex with antibacterial and other medicamentous agents was studied during influenza epidemic in 1975 due to port-chalmers virus of influenza a with increased numbers of viral-bacterial pneumonia. the viral-sta-phylococcal etiology of the infection was confirmed in 80 per cent of the cases under stationary conditions. various microorganism and most often staph aureus were isolated in addition to the viruses from the patient's sputum and ... | 1976 | 828482 |
| [antimicrobial susceptibility and molecular mechanisms of resistance to beta-lactams of gram-negative microorganisms--causative agents of nosocomial infections]. | profiles and mechanisms of resistance to beta-lactam antibiotics of isolates of gram-negative microorganisms, which are causative agents of infections in intensive care unit of hospital surgery department, were studied. two hundred and ten clinical isolates were studied: pseudomonas aeruginosa--86 strains (40.9%), acinetobacter baummanii--45 strains (21.4%), klebsiella pneumoniae--52 strains (24.8%), escherichia coli--23 strains (11%), enterobacter spp.--4 strains (1.9%). profiles of antibiotic ... | 2007 | 18038541 |
| [use of genetic and molecular characteristics of r plasmids as an epidemiological marker in an outbreak of hospital infection]. | antibiotic sensitivity of 38 strains of enteric bacteria, such as serratia marcescens klebsiella pneumoniae and others and ps. aeruginosa isolated during an outbreak of meningitis in a premature infant resuscitation department was studied. it was shown that all the isolates were multiple resistant, most frequently to 7 antibiotics. all the resistance markers were transferred on conjugation, segregation of some markers being observed. investigation of the plasmid composition of the clinical strai ... | 1984 | 6422842 |
