conclusions: with respect to the obtained results and regarding to the daily increase of the resistant microbial strains to the commercial antibiotics, it can be concluded that these extracts can be proper candidates of antibacterial substance against pathogenic bacterial species especially s. aureus, e. coli, k. pneumoniae and s. epidermidis. results: the extract of c. fistula was effective ag...

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...

background: the aim of this study was to determine the occurrence of virulence determinants and vancomycin- resistant genes among enterococcus faecalis and e. faecium obtained from various clinical sources. methods: the study was performed on the 280 enterococcal isolated from clinical specimens in hamadan hospitals, western iran in 2012-14. antibiotic susceptibility testing was performed using...

objective(s): the aim of the present study was to prepare, characterize, and evaluate solid lipid nanoparticles (slns) containing zataria multiflora essential oil (zeo). materials and methods: in this study, z. multiflora essential oil-loaded solid lipid nanoparticles (ze-slns) were prepared to improve its efficiency in controlling some fungal pathogens. slns containing z. multiflora essential ...
