background and objective: gastroenteritis is one of the most important diseases in the world. this disease is more critical among children, people with immune deficiency and the sufferers from mal-nutrition. shigella spp. as the most important cause of dysentery, causes much mortality around the world. increasing antibiotic resistance is one of the major health problems. this research aimed to ...

background and aims: acinetobacter baumannii is regarded as an important nosocomial pathogen around the world, especially in the intensive care unit that today seems to be resistant to the most antibiotics. therefore, this study aimed to trace classes 1, 2, and 3 integrin in the isolates resistant to acinetobacter baumannii. materials and methods: in this descriptive study, acinetobacter bauman...

conclusions the potential to form biofilm correlated with antibiotic resistance and ampc production in non-burn burn isolates of a. baumannii. on the other hand, the burn strains produced significantly higher amounts of esbl yet biofilm production was unrelated to antibiotic resistance or esbl-production. materials and methods sixty isolates of a. baumannii were employed of which, 30 were burn ...

conclusions only a few number of health workers do respect hygiene rules before and after catheterization. therefore, it is necessary to train health workers involved in such activities on good hygiene practices during catheterization. results two days later, (48 hours after the catheterization), 14 patients out of 60 (23.33%) presented with a urinary infection, of which 1 patient (1.66%) was a...

conclusions the current study results showed that silver nanoparticles produced by plantago ovata seed extract had an antibacterial effect on staphylococcus aureus which was resistant against cefixime, trimethoprim-sulfamethoxazole and penicillin. results the silver nanoparticles revealed gaussian distributions with the average diameter of 13 nm with some deviations, and results showed that the...

resistance to oxyimino cephalosporins antibiotics in enterobacteriaceae is primarily done by the extended spectrum β-lactamases (esbls). clear identification of risk factors for esbl-producing infections is necessary. therefore, efficient strategies can be developed to decrease outbreak of these infections. the aim of this study was to determine the antibacterial susceptibility and esbls patter...

background & objectives: pseudomonas aeruginosais one of the most important causes of nosocomial infections particularly in immunodeficient patients. several antibiotics such as betalactams, aminoglycosides and quinolones are used for the treatment of infections caused by this organism, but the prevalence of multidrug resistant strains has been reported frequently. beta lactamase production is ...

conclusion prevalence of p. aeruginosa producing esbl and mdr strains from our clinical samples and environment is still low. results the highest resistance rates from the isolated p. aeruginosa were shown against piperacillin, imipenem, cefotaxime, ceftriaxone, gentamicin, ceftazidime, aztreonam, and ciprofloxacin, respectively. seven isolates (9.2%) were esbl producers. more than 30% of the i...

Shigella is a major cause of dysentery across the world. Appropriate antibiotic treatment of shigellosis depends on resistance patterns. The present study was conducted to identify Shigella species and their antibiotic resistance patterns among dysenteric patients in Rezaei Hospital of Damghan. Isolation of Shigella species was conducted by specific culture medium and biochemical tests. The Shi...

conclusions antibiotic resistance gene cassettes may be carried on integron or other genetic elements. the purpose of this study was to detect integron or genomic islands involved in antibiotic resistance profile of the isolates of h. influenzae collected in this study. results of the twenty isolates, all (100%) were resistant to clindamycin, chloramphenicol and tetracycline, 95% to amoxicillin...
