results in this study, high resistances were found to nalidixic acid (59.7%) and gentamicin (52.3%) but high susceptibilities were found to ciprofloxacin (59.3%) and ceftriaxone (36.3%). conclusions according to the results obtained in this study ciprofloxacin is an effective antibiotic in e. coli infections. objectives the current study aimed to investigate the resistance of escherichia coli a...

objectives in this study, we explored a physical method of converting drug-resistant bacteria to drug-sensitive ones. materials and methods this is an in vitro case-control study, performed at the ionizing and non-ionizing radiation protection research center (inirprc), shiraz university of medical sciences (sums), shiraz, iran in 2014. all experiments were carried out using gram-negative bacte...

The development of antibiotic resistance is usually associated with genetic changes, either to the acquisition of resistance genes, or to mutations in elements relevant for the activity of the antibiotic. However, in some situations resistance can be achieved without any genetic alteration; this is called phenotypic resistance. Non-inherited resistance is associated to specific processes such a...

background: staphylococcus aureus is a major human pathogen. due to high prevalence of s. aureus infections and increasing resistance to antibiotics, physicians have been facing problems in choosing the appropriate empirical antibiotic therapy for such infections. objectives: the aim of this study was to determine the pattern of antibiotic resistance in s. aureus clinical isolates of mashhad qu...

Background: Acne vulgaris is a self-limited disease that mainly involves the sebaceous follicles. Systemic antibiotic is a common therapeutic modality, so bacterial resistance can be a problem. Objectives: Assessment of Propionibacterium resistance to erythromycin, tetracycline, clindamycin and spiramycin. Patients and Methods: Sampling was done on lesions of 123 patients with acne vulgaris who...
