BACKGROUND Screening of the ethnobotenical plants is a pre-requisite to evaluate their therapeutic potential and it can lead to the isolation of new bioactive compounds. METHODS The crude extracts and fractions of six medicinal important plants (Arisaema flavum, Debregeasia salicifolia, Carissa opaca, Pistacia integerrima, Aesculus indica, and Toona ciliata) were tested against three Gram pos...

statement of problem: dental plaque is the main source for dental caries and there is no proper vaccine that can affect dental plaques. objectives: daily use of an efficient anti-plaque product can be very beneficial in plaque control and, thus, prevention of caries. this study aims to evaluate the antibacterial effects of four products of chlorhexidine and fluoride on two types of cariogenic b...

Minocycline is a semi-synthetic tetracycline derivative and appears to be as effective as other tetracyclines and analogues. The present research work is on anti-microbial assay to demonstrate the minocycline is more effective on selected gram-positive than the gram-negative bacterial strains. It showed the highest zone of inhibition on Bacillus subtilis than Staphylococccu aureus when cultured...

For the study, 36 soil samples with roots parts were taken from root zone of better grown healthy pepper plants fields Kahramanmaras province. Bacterial isolations made collected samples. Overall, 713 isolates obtained bacteria colonies based on morphological characteristics differences. By measuring radius inhibition zone, ZHA17 was determined to be most effective isolate. Fifteen selected the...

Cocoa Ethanolic Extract (CEE) was observed for antibacterial activity against Escherichia coli. CEE at different concentrations in E. coli-seeded Mueller-Hinton agar medium, resulted zone of inhibition after 24 h incubation in 37°C. CEE concentrations at 15.6, 31.25, 62.5, 125, 250, 500 and 1,000 mg/ml, developed annular radius of inhibition 0.4, 1.0, 1.9, 3.3, 4.5, 5.3 and 6.31 mm respectively...

Six strains of Bacillus cereus exhibiting antifungal activity were isolated from local environment and optimized for growth conditions. The isolates appeared neutrophiles, grew best at aeration and were represented by thermophiles and mesophiles. Growth inhibition zones of varying diameters were observed when the isolates were tested against Saccharomyces cerevisiae on nutrient agar. Largest in...

introduction: the antimicrobial efficacy of root canal irrigant plays an important role in increasing the success of root canal treatment (rct). the aim of the present experimental study was to compare the antimicrobial activity of triphala (a plant-derived solution) with 0.5, 1, 2.5 and 5% concentrations of sodium hypochlorite (naocl), against enterococcus faecalis ( e. faecalis ). methods and...
