Olive mill wastewater polyphenol extract was tested for antimicrobial activity against 64 strains of Pseudomonas fluorescens responsible for mozzarella discolouration. The extract showed a minimum inhibitory concentration (MIC)50 value of 5 mg/mL and a MIC90 value of 7 mg/mL. The MBC50 and MBC90 values corresponded to 6 and 8 mg/mL, respectively. The MIC concentration (7 mg/mL) was demonstrated...
background: in this study, the efficacy of nitazoxanide in the treatment of helicobacter pylori isolates, which were resistant to metronidazole, was examined. methods: one hundred twenty two patients who underwent endoscopy examinations at kasra and laleh hospitals in tehran from november 2014 to july 2015 were enrolled. helicobacter pylori strains were isolated from the patients’ endoscopy b...
emergence of resistance among pathogenic bacteria against available antibiotics is posing a great challenge to the current world. thus, there is a great need to discover novel antibiotics. traditional plants have been proved to be novel source in the search of antimicrobial compounds. the current study pertained to the susceptibilities of some clinically significant bacterial species to various...

results of total 60 s. aureus isolates, 51 (85%) were mrsa, and of 60 cons, 7 (11.66%) were mrcons. the results showed that the mic of chlorhexidine for all 120 isolates was 1-16 μg/ml. 15 (12.5%) isolates carried qaca/b gene, 26 (21.7%) carried qacc gene, and 38 (31.7%) carried smr gene. conclusions maintenance of mrsa isolates in the attendance of low amounts of antiseptics could result in th...
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...
we consider of the antimicrobial activity on the ag nanoparticles(ag nps) aqueous solutions, which was prepared using a stabilizer, such as poly(n vinyl 2 pyrrolidone pvp , for staphylococcus aureus) s aureus and escherichia coli e coli by measuring the minimum inhibitory concentration mic . antimicrobial effect of ag nps for s aureus and e coli was investigated using disk diffusion method also...
Objective(s): This study aimed to investigate the effect of zinc oxide nanoparticles (ZnO-np) on biofilm formation and expression of the flu gene in uropathogenic Escherichia coli (UPEC) strains. Materials and Methods: Minimum inhibitory concentration (MIC) of ZnO-np was determined by agar dilution method. The effect of MIC and sub-MIC concentrations of ZnO-np on biofilm formation were determin...
Introduction:Salmonella typhi and paratyphi - related enteric fever still poses serious health risks to people all over the world. Ceftriaxone azithromycin were recommended as preferred treatments for following emergence of fluoroquinolone resistance. Several reports ceftriaxone resistance have also been reported, hence accurate medication susceptibility tracking is essential maintain empiric m...
