The aim study antibacterial effects of silver nanoparticles against resistant strains of E.coli bacteria.12 strains of E. coli strains arising urinary infection were isolated from hospitalized patient in zabolhospitals. Minimum inhibitory concentration of winter cherry were determined by dilution method in various concentration on bacteria. The highest MIC values was found to be 100ppm against ...

The extent to which antibiotic-resistant bacteria are excreted by humans who have not been exposed to antibiotics is not known. Children, who rarely receive fluoroquinolones, provide opportunities to assess the frequency of fecal excretion by fluoroquinolone-naïve hosts of fluoroquinolone-resistant gram-negative bacilli. Fresh nondiarrheal stools from children were processed by screening them o...

The emergence of clinically relevant ?-lactam-resistant bacteria poses a serious threat to human health and presents major challenge for medical treatment. How opportunistic pathogenic acquire antibiotic resistance the prevalence antibiotic-resistant in environment are still unclear. In this study, we further confirmed that selective pressure heavy metals contributes increase ampicillin-resista...

Under the conditions specified, there may be selected promptly from a hybrid stock of mice, of which 40 to 50 per cent die following a standard dose of B. enteritidis or St. Louis encephalitis virus, lines in which as high as 95 per cent and as low as 15 per cent succumb. Three lines,-one bacteria-susceptible-virus-susceptible, one bacteria-susceptible-virus-resistant, and one bacteria-resistan...

New agents are needed with the increasing prevalence of multidrug-resistant (MDR) bacteria. Identification plants activity against MDR bacteria is importance. The antimicrobial commercially available Graviola preparations 38 clinical and laboratory isolates, representing drug-sensitive Gram positive negative bacteria, was measured by broth microdilution. Commercially fruit, as well leaves/stems...

The aim of this study was to assess the prevalence of ESBL-producing E. coli in agricultural fields of Gorgan district, Golestan province. Soil samples were collected from 20 agricultural fields, half of them treated with chemical fertilizers and the rest with bovine manure. Two samples, from surface and a depth of 15cm, were taken. After enrichment and culture onto MacConkey agar, Pink colored...

to study the putative transfer of antibiotic resistance from broiler breeders to human, hen’s eggs and theirday-old chicks were examined for the presence of bacteria. the most frequently isolated organisms indecreasing order were: streptococcus spp., bacillus spp., staphylococcus spp., klebsiella spp., enterobacterspp. and escherichia coli followed by citrobacter spp., proteus spp. and pseudomo...

Multidrug-resistant gram-negative bacteria are an emerging problem. The present article addresses 2 relevant questions: (1) should active surveillance be performed to identify patients colonized with multidrug-resistant gram-negative bacteria, and (2) should contact isolation precautions be taken with patients colonized or infected with multidrug-resistant gram-negative bacteria? Data and varia...

Background and Objectives: Recently, the use of probiotics for the treatment of Urinary Tract Infections has become more popular. The use of probiotics in therapy is useful as only a few side effects such as destruction of resistant bacteria or disturbance of the intestinal microbiota have been reported. The aim of this study was to evaluate the probiotic effects of lactic acid bacteria by co-a...

Antimicrobial resistant zoonotic pathogens present on food constitute a direct risk to public health. Antimicrobial resistance genes in commensal or pathogenic strains form an indirect risk to public health, as they increase the gene pool from which pathogenic bacteria can pick up resistance traits. Food can be contaminated with antimicrobial resistant bacteria and/or antimicrobial resistance g...
