background and objectives: bacterial resistance to conventional antibiotics has become a widespread public health prob- lem. the aim of this study was to investigate the influence of zinc oxide nanoparticles (zno nps) on the antibacterial activity of several conventional antibiotics against pseudomonas aeruginosa. materials and methods: zno nps were prepared by solvothermal method and dispersed...

BACKGROUND The faecal reservoir provides optimal conditions for the transmission of resistance genes within and between bacterial species. As key transmitters of infection within communities, children are likely important contributors to endemic community resistance. We sought to determine the prevalence of antibiotic-resistant faecal Escherichia coli from asymptomatic children aged between 0 a...

The association of the emergence of bacterial resistance to clinical environments is common; however, aquatic environments, especially the polluted ones, also play a key role in this regard. Aquatic environments can act as facilitator for the exchange of mobile elements, responsible for resisting antibiotics. They even may stimulate the emergence and selection of these elements through contamin...

urine specimens collected from in-patients and out-patients in urmia imam hospital, northwest iran, were cultured on blood agar and eosin methylene blue agar. isolated bacteria were identified according to standard microbiological tests and then subjected to sensitivity testing according to routine method of disk agar diffusion technique. out of 8044 and 10425 urine specimens, 8.7% and 11.9% we...

In Spain, the inclusion of new antibiotics in hospital formularies is performed by the Infection Policy Committee or the Pharmacy and Therapeutic Committee, although now the decision is moving to a regional level. Criteria for the evaluation of new drugs include efficacy, safety and cost. For antimicrobial drugs evaluation it is necessary to consider local sensibility and impact in bacterial re...

one of the great challenges in the treatment of infectious diseases is the resistance of pathogenic bacteria against antibiotics, and antibiotic resistance to shigella is broadly observed in different parts of the world. the object of this study was to determine shigella antibiotic resistance pattern against the antibiotics such as ampicillin, amoxicillin, trimethoprim-sulfamethoxazole, chloram...
