abstract background: the invasion of microorganisms into the bloodstream and spread to different parts of body can cause disruption the functions of vital organs and even death. the proper and prompt treatment is essential and can significantly reduce morbidity and mortality rates. this study aimed to determine the frequency and the antimicrobial susceptibility of bacteria isolated from blood c...

background: recent analyses of hospital outbreaks have documented the spread of resistance to imipenem, which is cur­rently a major problem among gram positive and gram-negative bacteria. the aim of this study was to describe the rate of gram- positive and gram-negative isolates resistance to imipenem as an antibiotic. methods: recorded files of 242 hospitalized patients with at least one sampl...

the objective of this study was to determine the frequency of microorganisms isolated from blood samples of patients admitted to intensive care unit (icu), and the rate of their resistance to common administered antibiotics in an iranian icu. one-hundred patients with systemic inflammatory response syndromes (sirs), hospitalized in icu of sina hospital, tehran, iran, were entered to this cross-...

background and objectives: the emergence of extended-spectrum β-lactamase (esbl)-producing shigella spp.  is of increasing clinical concern specially in children worldwide. the aim of this study was to investigate the occurrence of extended-spectrum β-lactamase producing shigella spp. in tehran, iran. materials and methods: the study included all shigella isolates recovered from pediatric patie...

conclusions periodic evaluation of antimicrobial susceptibility for c. perfringens should be performed. harboring of enterotoxigenic c. perfringens in individuals not necessarily results in diarrhea. results of 136 stool samples including diarrhea [48] and non-diarrhea [88] ones, 83 (61.02%) c. perfringens were cultured. of these 83, 79 c. perfringens isolates showed the alpha-toxin (phospholip...

conclusions: ten percent of the isolates were positive for meca gene among the vancomycin-oxacillin resistant strains, while van gene was not detected in any of the isolates. the data obtained would be useful in clinical control of resistant staphylococcal strains. results: a total of 120 staphylococcus isolates were screened, out of which, 32 (26%) were susceptible to both methicillin and vanc...

background: human exposure to antibiotic resistant bacteria (arb) is a public health concern which could occur in a number of ways. wastewaters seem to play an important role in the dissemination of bacteria and antibiotic resistant genes (args) in our environment. the aim of this study was to evaluate the occurrence of three groups of arb and their resistance genes in hospital and municipal wa...

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...

background and objectives: the appearance of antibiotic resistance in streptococcus pneumoniae has raised a global concern over the past three decades. this study was conducted to determine the antimicrobial susceptibility of s. pneumoniae isolated from patients in children´s medical center (cmc) hospital during 2001 to 2011. materials and methods: during the 11 years period, a total of 194 s. ...

The present study aimed to evaluate the antibiotic resistance pattern of Escherichia coli strains isolatedfrom animals to ascertain the levels of antibiotic resistance pervasiveness. A total of 28 E. coli strains wereisolated from faecal samples and the antibiotic resistance pattern of E. coli strains was determined by meansof disc diffusion assay. The resistance pattern determined for all stra...
