Motility allows populations of bacteria to rapidly reach and colonize new microniches or microhabitats. The motility of rhizobia (symbiotic nitrogen-fixing bacteria that nodulate legume roots) is an important factor determining their competitive success. We evaluated the effects of temperature, incubation time, and seed exudates on swimming and swarming motility of five strains of Bradyrhizobiu...

BACKGROUND The main objective of this study was the phytochemical characterization of four indigenous essential oils obtained from spices and their antibacterial activities against the multidrug resistant clinical and soil isolates prevalent in Pakistan, and ATCC reference strains. METHODS Chemical composition of essential oils from four Pakistani spices cumin (Cuminum cyminum), cinnamon (Cin...

ObjectiveThe present work represents the green synthesis of silver nanoparticles using Withania coagulans extract and its antibacterial property. The synergy, additive, bacteriostatic and bactericidal effect of silver nanoparticles was determined against Enterococcus faecalis, Staphylococcus aureus, Escherichia coli, Proteus vulgaris, Salmonella typhi, and Vibrio cholerae. Methods <...

abstract       background and objective: probiotics are living microorganisms that have beneficial effects on the health of digestive system. the aim of this study was to evaluate the antimicrobial ability of acidic and neutral supernatants (culture supernatant) of lactic acid bacteria against common bacterial pathogens.        methods: four species of lactic acid bacteria (lactobacillus planta...

antimicrobial activity of the roots of eranthemum roseum (vahl) r.br. (dasmuli), were tested against different bacteria (including escherichia coli, staphylococcus aureus, bacillus subtilis, shigella sonnei, klebsiella pneumoniae, salmonella typhi, proteus vulgaris, pseudomonas aeruginosa) and fungi (such as candida albicans and aspergillus niger) by cup plate diffusion method. minimal inhibito...

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...

In the present research, In vitro study of antagonistic properties of fifty soil actinomycetes against 10 bacteria which were: Salmonella typhi, Klebsiella pneumoniae, Serratia marsecense, E. coli, Proteus vulgaris, Streptococcus faecalis, Staphylococcus aureus, Bacillus subtilis, Bacillus cereus and Micrococcus luteus showed that Six of them have inhibitory effects on both gram negative and gr...
