the introduction of newly devised wound dressing has been a major breakthrough in the management of wounds or infections. the aims of this paper are to isolate and identify bacterial species causing burn wound infections from a university-related iranian hospital as well as determination of the antimicrobial susceptibility of the isolated microorganisms to newly devised nanocomposite materials ...

background: escherichia coli and staphylococcus aureus as important food-borne pathogens are the main concerns of food producers and consumers which create a lot of problems worldwide. the objective of this study was to investigate the inhibitory effect of monolaurin alone and in combination with edta on viability of e. coli and s. aureus in culture media and iranian white cheese. methods: the ...

The purpose of this study was to determine the antibacterial susceptibility of field isolates of Mycoplasma bovis originating from the upper respiratory tract of cattle of different ages. Bacteriological examination of 90 nasal swabs collected from calves at three months of age identified M. bovis in 31 (34.44%) samples. Seventeen (18.88%) of these animals still housed M. bovis in their nasal c...

abstract       background and objective: enterococci are relatively nonvirulent bacteria that rarely cause disease. antimicrobial treatment of enterococci is often challenging due to their antibiotic resistance. this study aimed to investigate the antibacterial activity of aqueous extract of garlic against enterococcal isolates.     methods: in this descriptive study, 120 enterococcus isolates ...

objective: bioactive glass 45s5 is a surface reactive glass-ceramic biomaterial, developed in 1969. bag 45s5 with particle size of 20-60 nm has the ability of bone regeneration, broad spectrum antibacterial effect, repairs and replaces diseased or damaged bone. the aim of this study was to evaluate the antibacterial activity and determine mic and mbc values of nano-bag45s5 on streptococcus muta...

OBJECTIVES The antioxidant tert-butylhydroquinone (TBHQ) is a food additive reported to have antibacterial activity, and may therefore have application in the healthcare setting. This study sought to characterize the antibacterial activity and mode of action of TBHQ and its oxidation product, tert-butylbenzoquinone (TBBQ). METHODS The stability of TBHQ/TBBQ was studied in buffer. Susceptibili...

Hexane, petroleum ether, chloroform, ethyl acetate, acetone and methanol extracts of Tulsi (Ocimum sanctum) were analyzed for determination antibacterial activity against enteric-pathogenic bacteria Escherichia coli, Shizella dysenteriae, Salmonella typhi, Pseudomonas aeruginosa Vibrio cholerae using agar well diffusion method. Only extract all them exhibited an inhibiting effect on the develop...

Propolis is a resinous plant material collected by bees to defend their colony. This study evaluated the antibacterial and antioxidant activities of ethanolic extracts Ugandan propolis in three bee-keeping agro-ecological zones. Antibacterial assays were performed on two Gram-positive (S. aureus S. pneumoniae) Gram-negative (E. coli P. aeruginosa) bacteria within concentration range ~1.6 100 mg...

Background: Pulicaria gnaphalodes, Ducrosia anethifolia, Trachyspermum copticum, Foeniculum vulgare Mill and Majorana hortensis Minch are widely used as herbal plants in traditional medicine and they have been reported to have a variety of therapeutic effects. This study was carried out to evaluate the antimicrobial effects of essential oils (EOs) extracted from these medicinal herbs against si...
