Hibiscus rosa sinensis, a member of the Malvaceae family, is widely cultivated in the tropics as an ornamental plant. It is often planted as a fence or hedge plant, and has several forms of flowers with varying colours. It is also used in traditional medicine to induce abortion, ease menstrual cramps, assist in childbirth and relieve headache, fever and inflammation. In this study, we evaluated...

The objective of this study was to determine the chemical composition and antibacterial activity of essential oils (EOs) of Tagetes minuta against three phytopathogenic bacteria Pseudomonas savastanoi pv. phaseolicola, Xanthomonas axonopodis pv. phaseoli, and Xanthomonas axonopodis pv. manihotis. The essential oils were extracted using steam distillation method in a modified Clevenger-type appa...

The present paper investigates to examine the in vitro antibacterial activities of the chromium nanopartical which preparied by -green synthesis techniquesreduction of potassium dichromate solution with Arachis hypogaea leaf extract containing reducing sugars which act as reducing agent. Chromium nanoparticles were shown to be an effective control of two phytopathogenic bacteria, namely Erwinia...

The antibacterial activity of crude extracts of Sargassum longifolium and Gracilaria corticata collected from the Gulf of Mannar Coast, Tamilnadu, India against common shrimp pathogens were tested by disc diffusion method. Three different solvents namely aqueous, ethanol and methanol were used for extraction. The qualitative phytochemical analysis revealed the presence of carbohydrates, protein...

antibiotic resistance of intensive care unit (icu) born aerobic gram-negative bacteria was evaluated during a six months period at a teaching hospital in tehran, and determination of the validity of the results obtained from disc diffusion tests, using discs manufactured in iran. disc susceptibility tests using iranian and standard discs (diffusion discs available in international markets) were...

In continuation of Nepalese medicinal plant screening research, we have examined the antibacterial property of 40 methanol crude extracts in vitro using disc diffusion method against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis. Overall, 95 % of the extracts showed antibacterial activity against at least one Gram-negative bacteria and 90 % of the extract...

In present study, methanol extracts of the Chlorophycean group of seaweeds have been tested for their antibacterial activity against oral bacteria causing dental caries. Different concentrations of the extracts of the four species of seaweedsChaetomorpha antennina, Cladophora fascicularis, Spongomorpha indica and Ulva fasciata collected from sea coast of Visakhapatnam have been tested for their...

The potent antibacterial and antiviral activity of petroleum ether, ethyl acetate, successive and crude methanolic extracts of J. curcas leaves was evaluated. The antibacterial activity of J. curcas extracts was studied against 6 common foods borne bacteria using disc diffusion assay. The antibacterial activity of J. curcas extracts showed different degrees of inhibition zone against the pathog...

With increased prevalence of antibioticresistant bacterial, finding new sources with antibacterial activity could be an effective help in diseases. The antibacterial activity and Minimal Inhibitory Concentration (MIC) of the extracts of Calendula Officinalis L., Achillea millefolium L. Millefolium L., Allium haemanthoides Boiss. & Reut. ex Regel, Allium ampeloprasum L. and Echinophora platyloba...

Staphylococcus aureus is one of the most common causes of nosocomial infections. The purpose of this study was the synthesis and in vitro evaluation of antimicrobial activity of 10 new 3-oxazolidin-2-one analogues on 12 methicillin resistant S. aureus (MRSA) clinical isolates. S. aureus confirmation was achieved via catalase and coagulase test. Molecular characterization of MRSA was performed b...
