background and objectives: acinetobacter spp. are important causes of nosocomial infections. they possess various antibiotic resistance mechanisms including extended spectrum beta lactamases (esbls). the aim of this study was to determine antibiotic resistance profile of acinetobacter clinical isolates especially among esbl-producing strains and to investigate the antimicrobial effects of oleo-...

staphylococcus aureus is a hazard to human health since they can cause a wide variety of hospital-associated infections ranging from minor skin infections to post-operative wound infections and food poisoning which produces many different virulence factors, including enterotoxins (ses). although  studies  have  been  done  regarding  the difference  between  virulence  factors  of  sensitive st...

abstractpropionibacterium acnes is propounded as one of the significant factors in occurrence of acne. today, due to development of the antibiotic resistance, most of the acne treatments are faced with failure. in order to determine the antibiotic resistance of the p.acnes strains isolated from the patients with acne, this research has been carried out. 70 samples collected using microbial cult...

background: one of the main causes of sexually transmitted diseases is group b β- hemolytic streptococci (gbs) multiplying in the genital tracts. penicillin is the most common drug for the treatment of infections caused by these bacteria, but in patients suffering from penicillin allergy, erythromycin and clindamycin are used as alternative therapeutic drugs against gbs. recently, resistance to...

background :  emerging antibacterial resistance rates and beta-lactamase producing bacteria recovered from uti is an increasing problem in different regions, limiting therapeutic options. therefore, this survey consider to use the extract and essence of the citrus aurantium (which have a so many rate of planting in iran) and also survey on extract on bacteria whose cause urinary tract infection...

pseudomonas aeruginosa is among the most important pathogens in the nosocomial infections. a genetic mobile element, the integron, is one of the major agents involved in dissemination of multi-drug resistance among gram negative bacteria. during a descriptive study from october 2009 to august 2010, some 130 p. aeruginosa clinical isolates were collected from different wards of three hospitals i...

introduction: resistance of pathogenic organisms to countenance antibiotics has become a worldwide problem with serious consequences on the treatment of infectious diseases. the aim of this study was to evaluate antibiotic resistance and also the detection of transferred antibiotic resistance by plasmid in clinical proteus isolates. materials and methods: a total of 250 urine samples were colle...
