The antibacterial activity of leaf extract of mangroves, namely, Rhizophora mucronata, Sonneratia alba and Exoecaria agallocha from Chorao island, Goa was investigated against human bacterial pathogens Staphylococcus aureus, Streptococcus sp., Salmonella typhi, Proteus vulgaris and Proteus mirabilis. As compared to aqueous, ethanol extract showed broad-spectrum activity. The multidrug-resistant...

In this study, the antimicrobial activity of crude extracts of flower, fruit, stem and leaf of Conocarpus erectus and purified tannins were evaluated against three fungi and seven Gram-positive, Gram-negative and acid-fast bacteria. While, by disc diffusion method, extracts of different parts of C.erectus were active only against Saccharomyces cerevisiae, purified tannins were active against Sa...

during this research, bacteria resistant to metals were evaluated in the soil of isfahan province.according to the sampling locations the soils are classified as agricultural soils, non-agricultural soils andsediments of the zayanderood riverbank. the bacteria resistant to lead (2 mm), copper (5 mm), cadmium(0.5 mm) and arsenic (5 mm) were identified, and then during later stages, the minimum i...

conclusions ethanol extracts of p. granatum (pericarp, leaves, flowers, seeds) have antibacterial effects against p. haemolytica which has shown resistance to all studied antibiotics. background continuous researches on drugs that solve the problem of growing number of resistant bacteria are important. objectives this research aims to investigate the effectiveness of anti-bacterial properties s...

this laboratory study simultaneously was conducted to evaluate the resistance to heavy metals, silver, cadmium and a number of commonly used antibiotics. sampling was done in 2014 of the two silver workshops in isfahan, and the inlet of phase 2 of shahin shahr wastewater treatment plant, isfahan. to isolate resistant bacteria to metal silver and cadmium and review multiple resistance to other m...

b a ckground: the brown-banded cockroach, supella longipalpa is known as a carrier of pathogenic bacteria in urban environments, but its role is not well documented regarding the carriage of antibiotic-resistant pathogenic bacte- ria in iran. the aim of this study was to determine the resistance bacteria isolated from the brown-banded cockroach in ahvaz, south west of iran. m e t hods: totally ...

background and objectives : due to the extensive use of antibiotics, the spread of drug-resistant bacteria is one of the most worrisome threats to public health. one strategy that can be used to overcome potential shortcomings might be the inactivation of these organisms by photodynamic therapy. in this study, we have investigated whether drug-resistant wound-associated organisms (staphylococcu...

Objective: The aim of the present study was to screen phytochemicals and antimicrobial activities of the extracts of three medicinal plants viz. Calotropis gigantea, Lawsonia inermis and Trigonella foenum-graecum. Methods: The methanolic extracts of the three plants were tested against clinical isolates of five bacterial strains (Staphylococcus aureus, Bacillus cereus, Methicillin Resistant Sta...

Ethanolic extracts of 45 Indian medicinal plants traditionally used in medicine were studied for their antimicrobial activity against certain drug-resistant bacteria and a yeast Candida albicans of clinical origin. Of these, 40 plant extracts showed varied levels of antimicrobial activity against one or more test bacteria. Anticandidal activity was detected in 24 plant extracts. Overall, broad-...

Datura stramonium is commonly known as Jimson weed and is widely used in phytomedicine to treat epilepsy, skin ulcers, etc as well as to kill the microbes associated with wound lesions. Antimicrobial activity of ethyl acetate and methanol extracts of leaves and flowers of Datura stramonium was investigated against antibiotic resistant pathogenic bacteria isolated from pus samples of skin and ur...
