improving cleaning and disinfection performance must be taken into account for prevention and control of infection. health care settings are engaged in a battle against healthcare associated infection (hais). the importance of infection prevention and control is increasing due to rapidly developing strains of multi-drug resistant organisms (mdros) that can result in serious illness and even dea...

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...

rubella a benign viral and modestly contagious illness in children, becomes a very dangerous story when acquired by pregnant women. the potential of its teratogenicity is obvious. since prevention is preferred to treatment, diagnosis of rubella infection syndrome being difficult in early stages of pregnancy, the uncertainly about fetuses being really infected and therapeutic abortion because of...

staphylococcus aureus is a major human pathogen producing different types of toxins. enterotoxin a ( sea ) is the most common type among clinical and food-related strains. the aim of the present study was to examine the prevalence of sea in clinical isolates of s. aureus . moreover, the correlation between sea producing strains and type of infection as well as resistance to antibiotics is also ...

purpose : identifying the predisposing factors of the infectious keratitis results in understanding the underlying mechanisms of its expansion and severity that is essential for initiation of optimal empirical antimicrobial therapy. this study identified main predisposing factors of bacterial keratitis in a sample of iranian population. methods : ninety patients with bacterial keratitis were pr...

the recognition of seasonal patterns in infectious disease occurrence dates back at least as far as the hippocratic era, but the mechanisms underlying these fluctuations remain poorly understood. many classes of mechanistic hypotheses have been proposed to explain seasonality of various directly transmitted diseases, including at least the following; human activity, seasonal variability in huma...

background: the prevalence of antimicrobial resistance among enterobacteriaceae is increasing worldwide. identification of pathogens and their resistance to antimicrobials is mandatory for successful empiric antibiotic treatment. the aim of this study was to investigate the prevalence of antimicrobial resistance of enterobacteriaceae isolated from hospital-acquired and community-acquired infect...

objectives in the current case control study, we aimed to compare the histopathological findings of liver to the ccr5δ32 bpdel mutation profiles, expression and some other clinical findings in patients with chronic hcv infection. background the specific antiviral t cells provide cc chemokine receptor 5 (ccr5) for the immune response during the hepatitis c virus (hcv) infection. heterogenous and...

introduction: traumatic ulcers are one of the most common causes of referral to emergency wards and interfere with wound healing. even in a complete sterile condition, all of the ulcers may be contaminated with bacteria, but a few of them progress and cause clinical manifestations. there is a controversy on the use prophylactic antibiotics in traumatic ulcers. in this study we compare the effic...

background and objectives: infection is the most common cause of death among burnt patients and infection control decrease the rate of mortality. the use of sticky mat can control contamination by preventing the entrance microorganisms into the hospital wards. this study was designed to evaluate the sticky mats effect in reduction of microorganism’s entry by personnel shoes to burn intensive ca...
