infectious diseases are one of the most common causes of morbidity and mortality and the spread of resistant microorganisms is playing a significant role in this regard. the purpose of this study was to assess the trend in antimicrobial resistance of gram-positive bacteria at the main referral teaching hospital in tehran during a 4-year period. all patients' biological isolates such as blood, u...

background: acinetobacter baumannii is an opportunistic and gram-negative coccobacillus. this opportunistic pathogen infectivity, especially in the intensive care units of hospitals is extensive worldwide. due to the incremental pattern of antibiotic resistance, this study was carried out to track the class i, ii and iii integrons in acinetobacter baumannii isolated from hospitalized cases in m...

objective(s):helicobacter pylori (h. pylori) is a pathogenic bacterium that colonizes the stomachs of approximately 50% of the world’s population. resistance of h. pylori to antibiotics is considered as the main reason for the failure to eradicate this bacterium. the aim of this study was to determine the rate of resistant h. pylori strains to various antimicrobial agents in different areas of ...

introduction: the inappropriate use of broad- spectrum antimicrobials in intensive care units (icu) is a universal problem. the main goal of this study was to implement antibiotic stewardship program (abs) concentrated on vancomycin and carbapenems, in pediatric icu (picu) of sheikh hospital. as an accessory purpose we looked for the effect of abs on the rate of antibiotic administration, lengt...

background and objectives: the prevalence of vibrio parahaemolyticus has been reported from ponnani earlier, however incidence of multidrug resistant strains have been encountered recently in clinical laboratories. the source for such strains and their presence in this major fish landing centre has been investigated. materials and methods: antibiotic sensitivity tests on isolates of v. parahaem...

medical compounds, especially antibiotics, in which remains in milk and dairy products on the one hand causes health problems such as allergic reactions and development of bacterial resistance to antibiotics are a serious threat to the health of consumers , and on the other hand, industrial troubles such as failure to produce fermented products can cause the milk back to the rancher. the purpos...

conclusions the remarkable rates of biofilm production ability among clinically isolated staphylococci emphasize the necessity of more effective infections control policies to prevent biofilm formation on medical devices and hospital environmental surfaces. background biofilm formation capacity is recognized as an important virulence factor in staphylococci that makes the organisms more resista...

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...
