From a Pseudomonas aeruginosa hospital isolate a new pyoverdin was isolated. It is identical with that of Pseudomonas aeruginosa strain R except that in the peptide chain L-Gln is missing.

The alkaline proteinase gene from Pseudomonas aeruginosa IFO 3455 was cloned and expressed in Escherichia coli.

objective: infections are increasing caused by antibiotic-resistant pseudomonas aeruginosa day by day. for this reason, many researchers have tried to find new compounds as alternative antibiotics. the purpose of this study was to evaluate the effect of yarrow extract, green tea and ajowan  on pseudomonas aeruginosa. methods: extraction  of achillea, green tea and ajowan was done with rotary. f...

conclusions the results of the present study showed that in comparison with previously published primer sets, p. aeruginosa infection can be diagnosed with higher sensitivity and specificity by the conventional pcr assay using the newly designed primers. it was also shown that the results of the pcr assay on clinical samples of severe infections became positive much earlier than the results of ...

conclusions induction of coccoid form of p. aeruginosa may be one of the important reasons for antibiotic treatment failure; therefore, prescribed dose of antibiotics should be carefully managed to prevent increasing antibiotic resistance and coccoid bacteria induction. results all used antibiotics at sub mic concentration had capability to induce coccoid bacteria. the highest rate of induced c...

conclusions multidrug resistance was significantly associated with mbl production in p. aeruginosa. early detection of mbl-producing p. aeruginosa and hospital antibiotic policy prescription helps proper antimicrobial therapy and avoidance of dissemination of these multidrug resistance isolates. background resistant pseudomonas aeruginosa is a serious concern for antimicrobial therapy, as the c...

background: quaternary ammonium compounds (qac), which contain benzalkonium chloride as the most widely used agent, are employed as wound and skin antiseptics, as well as disinfectants in hospitals. the resistance mechanism to disinfectants is usually determine by genes which are related to resistance to quaternary ammonium compounds, namely, qace, qacδe1, qacδe1 that are found in gram-negative...

background and objectives: pseudomonas aeruginosa is a frequent opportunistic pathogen in health care associated infections that is highly resistant to the majority of β-lactams. the aims of this study were to access the antimicrobial susceptibility pattern of p. aeruginosa isolated from educational hospitals of qazvin and alborz provinces, to determine the prevalence of metallo-β-lactamase (mb...

background pseudomonas aeruginosa is one of the most important agents causing nosocomial infections worldwide. multidrug resistance of isolated bacteria from nosocomial infections makes it difficult and sometimes impossible to treat. objectives the aim of the present study was to investigate the antibiotic resistance and association between blaimp and blavim genes with resistance to meropenem a...
