objective(s):urinary tract infection (uti) caused by bacteria is one of the most frequent infections in human population. inappropriate use of antibiotics, often leads to appearance of drug resistance in bacteria. however, use of probiotic bacteria has been suggested as a partial replacement. this study was aimed to assess the antagonistic effects of lactobacillus standard strains against bacte...

conclusions according to the results, six strains were resistant to six or seven antibiotics and all strains were at least resistant to two antibiotics. however, for each of these resistant bacteria one bacteriophage was isolated from environmental samples, which showed the effectiveness of bacteriophages to remove clinically resistant e. coli strains. effective phages in vitro showed effective...

INTRODUCTION Wound infections remain a public health problem, despite the progress made on improving surgical techniques and antibiotic prophylaxis application. Misuse of antibiotics to prevent bacterial infections leads to increased bacterial resistance and their dissemination. MATERIAL AND METHODS The study refers to 470 samples taken from wound infections of which only multi-drug resistant...

To the Editor: Over the past 10 years in North America and western Europe, a resurgence of bedbugs (Cimex lectularius) has occurred (1). Although the basis for this resurgence is unclear, large bedbug infestations have been attributed to increased worldwide travel, altered insecticide management, and increased resistance to pesticides (2). Marginalized populations in large urban centers appear ...

To the Editor: The article by Harris et al., published in the August 2007 issue of Emerging Infectious Diseases, examined the risk factors for selecting extended-spectrum β-lactamase–producing Enterobacteriaceae in intensive-care patients and found that exposure to piperacillin/tazobactam and vancomycin were independent risk factors (1). Although antimicrobial drug use has been historically lin...

The use of colistin for the treatment of multiresistant bacteria has led to the emergence of colistin-resistant strains of Gram-negative bacilli. Treatment of infections caused by these pan-drug-resistant bacteria is difficult owing to the paucity of effective antibiotics. We report two cases of ventilator-associated respiratory infection caused by pan-drug-resistant, colistin-resistant Pseudom...

during this research, bacteria resistant to metals were evaluated in the soil of isfahan province.according to the sampling locations the soils are classified as agricultural soils, non-agricultural soils andsediments of the zayanderood riverbank. the bacteria resistant to lead (2 mm), copper (5 mm), cadmium(0.5 mm) and arsenic (5 mm) were identified, and then during later stages, the minimum i...
