Pseudomonas aeruginosa is an increasing prevalent opportunistic human pathogen most common gram-negative bacteria found in nosocomial infections. Despite improvements in antibiotic therapy, Pseudomonas aeruginosa is intrinsically resistant to a number of antimicrobial agents. [1] It is mainly present as a saprophyte in warm moist conditions in the environment including sinks, drains, respirator...

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...

Background and Objective: Pseudomonas aeruginosa (P. aeruginosa) causes serious nosocomial and non-nosocomial infections. blaOxacillinases (OXA)-23 and blaOXA24/40 provide resistance to carbapenem antibiotics. The aim of this study was assessment of blaOXA-23 and blaOXA-24/40 in P. aeruginosa isolated from patients with nosocomial and non-nosocomial infections. Me...

An outbreak of gentamicin- and tobramycin-resistant Pseudomonas aeruginosa infection occurred in a surgical ward over a three-month period. Resistant Ps. aeruginosa strains with the same serological, phage, and pyocin type were cultured from the urine of six patients. Identical organisms were found on urine bottles, bedpans, and the hands of attendant staff. Inadequate disinfection played a maj...

conclusions our findings showed a high occurrence of metallo-β-lactamase production among p. aeruginosa isolates in burn patient infections in our region. also, there are p. aeruginosa isolates carrying the bla-vim-1 and bla-vim-2 genes in isfahan province. background metallo-β-lactamase-production among gram-negative bacteria, including pseudomonas aeruginosa, has become a challenge for treatm...

cladophora and enteromorpha are the filamentous green-algal genuses that have a widespread distribution in caspian sea coast. the aim of this study was to assess the antimicrobial activities of cladophora and enteromorpha in south of caspian sea. antibacterial activities of hydroalcoholic extracts of five different gram negative and positive bacteria including staphylococcus aureus, bacillus su...

the aim of the study was to determine the resistance patterns of pseudomonas aeruginosa isolates recovered from patients with surgical wounds in hospitals and also to investigate their epidemiological relatedness using molecular typing techniques. twenty pseudomonas sp. isolated from surgical wounds were subjected to antibiotic susceptibility testing by disk diffusion, plasmid profile, sds-page...

background pseudomonas aeruginosa is a leading cause of infections especially in patients with weakened immune systems. this pathogen is intrinsically resistant to many antibacterial agents. objectives the aim of this study was to survey the antibiotic resistance pattern and frequency of bla oxa10 gene in carbapenemase producing p. aeruginosa isolated from patients in isfahan hospitals. materia...
