background and objective: diabetes mellitus is one of the main problems in health systems in the world. diabetic foot infections (dfi) is one of the main complications and the most cause  of non-traumatic lower limb amputation .this study aimed to determine the prevalence of bacteria involved in dfi and their antibiotic resistance in patients with dfi diagnosis. patients and methods: this desc...

Some Azomethines of 5-amino isophthalic acid were synthesized and their antibacterial activity was studied in DMSO against four Gram positive Bacillus cereus ATCC11778, Staphylococcus aureus ATCC29737, Staphylococcus epidermidids NCIM2493 and Micrococcus luteus ATCC10240, and three Gram negative bacteria viz. Proteus mirabilis NCIM2241, Escherichia coli ATCC25922 and Klebsiella aerogenes NICM20...

background and objectives: the artemisia genus of asteraceae family is represented by 34 species in iran. artemisia sieberi grows wild in different regions of iran and grows in desert and semi- desert climate and has forage value for animals and also medicinal properties for humans. in this study we examined the antimicrobial effects of a. sieberi. materials and methods: the antimicrobial activ...

The reversal of the inhibitory action of antiseptics by substances showing a specific affinity for the inhibiting agent has been reported for many compounds, the most striking effect probably being the reversal of the action of mercurials by H2S, glutathione, sodium thioglycolate, etc. Valko and DuBois (1944) have reported that the germicidal action of cationic detergents against both gram-posi...

background: treatment of chronic sinusitis is complicated due to increase of antibiotic-resistant bacteria. the aim of this study was to determine the multidrug resistance (mdr) pattern of the bacteria causing chronic sinusitis in north of iran. methods: this cross-sectional study was carried out on patients with chronic sinusitis. bacterial susceptibility to antimicrobial agents was determined...

BACKGROUND For precise diagnosis of urinary tract infections (UTI), and selection of the appropriate prescriptions for their treatment, we explored a simple and rapid method of discriminating gram-positive and gram-negative bacteria in liquid samples. METHODOLOGY/PRINCIPAL FINDINGS We employed the NaOH-sodium dodecyl sulfate (SDS) solution conventionally used for plasmid extraction from Esche...

in this study, the aerial parts of pimpinella puberula were collected from ramhormoz and mashhad (khuzestan and khorasan provinces) at the vegetative, flowering and seeding stages. essential oils from the whole aerial parts as well as stem/leaf, inflorescence, unripe and ripe seeds, were isolated by hydro-distillation. the yields of essential oil obtained from the ramhormoz samples were 0.49%, ...

Plant growth and development are significantly influenced by the presence and activity of microorganisms. To date, the best-studied plant-interacting microbes are Gram-negative bacteria, but many representatives of both the high and low G+C Gram-positives have excellent biocontrol, plant growth-promoting and bioremediation activities. Moreover, actinorhizal symbioses largely contribute to the g...

biotics having low toxicity and high activities against both Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA) and Gram-negative bacteria including Pseudomonas aeruginosa (P. aeruginosa), which are the main bacteria causing nosocomial infections, are now urgently required. Recently, we introduced cefoselis (CFSL)4'5), which shows potent broadspectrum activity a...
