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...

Analysis of the global burden of antimicrobial resistance may give answers to several questions important for treatment decisions: Does overall antibiotic consumption drive antibiotic resistance? Why are there differences in consumption between countries? Are there differences between penicillins, cephalosporins, and macrolides in terms of resistance induction? Antibiotic consumption appears to...

Background: Urinary tract infection (UTI) is one of the most common human bacterial infections. The frequent use of antibiotics is associated with increased resistance of many bacterial agents to the treatment.Materials and Methods: A total of 9456 urine specimens were collected from patients referring to Pol-e Dokhtar health centers. All urine samples were inoculated on blood agar plates...

background methicillin-resistant staphylococcus aureus (mrsa) is known as a common pathogen in nosocomial and community-acquired infections. sewage acts as an environmental reservoir and may have a significant role in development and dissemination of antibiotic resistance. objectives this study was undertaken to determine the epidemiological relatedness between the mrsa isolated from sewage and...

BACKGROUND AND AIMS Prevalence of H. pylori antibiotic resistance is increasing worldwide, and it is the main factor affecting efficacy of current therapeutic regimens. Our aim was to review recent data on H. pylori resistance towards antibiotics in different countries. METHODS A systematic review of studies concerning primary H. pylori antibiotic resistance published through January 2006 to ...

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...

Weaned pigs were separated into eight treatments including a control without exposure to apramycin; a control with exposure to apramycin; and apramycin plus either cold stress, heat stress, overcrowding, intermingling, poor sanitation, or intervention with oxytetracycline, to determine the effects of management and environmental conditions on antibiotic resistance among indigenous Escherichia c...
