abstract       background and objective: due to the continuous increase of multidrug-resistant acinetobacter baumannii strains around the world, decision making for an effective treatment of infections caused by this organism depends on the results of antimicrobial susceptibility tests. in this study, the validity of disk diffusion and e-test methods was assessed by their comparison with the re...

in this study, penicillium digitatum, the causes of green mould disease of orange fruits, were isolated from infected fruit in bam city. antifungal activity of three different plant essential oils eucalyptus camaldulensis, zataria multiflora, myrtus communis at 50, 100, 150 and 200 ppm concentration, have been evaluated. mic (minimum inhibitory concentration) and growth inhibition zone diameter...

conclusions finally, it can be suggested that the extracts of this plant be applied as antimicrobial agents against these pathogens, particularly in biofilm forms. results the results showed that the a. sativum l. extract discs did not have any zone of inhibition for the tested bacteria. however, the mic values of a. sativum l. extracts (0.078 - 2.5 mg/ml) confirmed the high ability of these ex...

nowadays, uncontrolled and frequent use of antibiotics may cause emergence of microbial resistanceamong pathogenic agents. therefore, the use of new synthetic and natural antimicrobial compounds isinevitable. one source of natural compounds in this respect comes from plants. the purpose of this study was to examine the antibacterial effects of peel extracts from sour and sweet pomegranate. meth...

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...
