conclusions the study results showed that stimulation of the american cockroach’s immunity system lead to production of antibacterial proteins and peptides which had inhibitory effect on the bacteria, depending on the bacterial strains and their sensitivity. likely this feature of insects can be used as therapeutic strategies to produce natural antimicrobial compounds against the pathogenic bac...

infective endocarditis is one of the most severe complications of parenteral drug abuse. the outstanding clinical feature of infective endocarditis in intravenous drug abusers is the high incidence of right-sided valve infection, and the tricuspid valve is involved in 60% to 70% of the cases. we herein report a case of isolated pulmonic valve infective endocarditis with a native pulmonary valve.

background: yogurt is one of the most popular food diets with refreshing taste, nutritional, and health benefits. the objective of this study was to investigate the effect of three herbal essential oils (eos) including peppermint, basil, and zataria on viability of the probiotic bacteria in yogurt samples and to evaluate the antimicrobial activities of the produced probiotic yogurts against esc...

background: multidrug resistant enterobacteriaceae which was confined to the hospital environments is now emerging in the domestic food related environments as well. the main objective of the present study was to investigate the prevalence of antibiotic resistant enterobacteriaceae in the domestic food related environments.  methods: resistance to ampicillin, chloramphenicol, ciprofloxacin, gen...

materials and methods in this study, biodegradation of amoxicillin by baf was evaluated in the aquatic environment. in order to assess amoxicillin removal from the aquatic environment, this bioreactor was fed with synthetic wastewater at four amoxicillin concentration levels and three hrts. results the results showed that maximum amoxicillin and chemical oxygen demand (cod) removals by aerated ...

background and aim: bacterial elimination from root canal system is one of the aims in endodontic treatments, so the addition of antibiotics to sealers can increase their antimicrobial efficacy, as in this study we are determining the in-vitro antimicrobial effect of ah26 and ah plus sealers mixed with amoxicillin, triple antibiotic pastes and nanosilver on enterococcus faecalis. materials and ...

background: innovative bioactive films incorporated with antimicrobial agents have been recently developed for food preservation. the aim of this study was to evaluate antibacterial activity of polylactic acid (pla) films incorporated with ziziphora clinopodioides essential oil (zeo) and ethanolic propolis extract (epe) against some common food-borne pathogens. methods: the volatile chemical co...

background and objective:   the aim of the study was to evaluate the clinical effects of a mouthwash containing sage (salvia officinalis) extracts on streptococcus mutans (sm) causing dental plaque in school-aged children. material and methods: a double blind clinical trial study was conducted in a dormitory on 70 girls aged 11-14 years having the same socioeconomic and oral hygiene conditions....

non-steroidal anti-inflammatory drugs (nsaids) have shown antibacterial activity in some recent studies. the aim of this study was to evaluate the antibacterial effect of diclofenac against enterococcus faecalis (e. faecalis) as a resistant endodontic bacterium in comparison with ibuprofen, calcium hydroxide and amoxicillin.the antibacterial activity of materials was evaluated using agar diffus...

background silver has been used from ancient times by humans, and recently nanoparticles of silver have been used in many aspects of human life including as a potent antibacterial agent. objectives in the current study a completely green method to prepare silver nanoparticles is reported. two types of starches (potato and corn starches) were used to produce and stabilize silver nanoparticles. a...
