The major metabolites of Diopsyros melanoxylon viz. amyrins and ursolic acid and their lipophilic 3-O-fatty acid ester chains (C12-C18), which are synthesized now under mild esterification conditions in excellent yields (80-95%), were evaluated for their antimicrobial activity against a series of Gram positive and Gram negative bacteria. Significantly these compounds were found to exhibit poten...

Bactericidal activity of crude extracts from Asparagus racemosus were screened against eight pathogenic strains which belongs to Bacillus subtilis, Staphylococcus aureus, Micrococcus luteus, Escherischia coli, Vibrio cholerae, Shigella dysenteriae , Shigella flexneri and Pseudomonas aeruginosa. The chloroform and ethanolic extract exhibited predominant antibacterial activity against all the bac...

BACKGROUND Bacterial vaginosis is a global concern due to the increased risk of acquisition of sexually transmitted infections. OBJECTIVES To determine the prevalence of bacterial vaginosis and bacteria causing aerobic vaginitis. METHODS A cross-sectional study was conducted among 210 patients between September 2015 and July 2016 at St. Paul's Hospital. Gram-stained vaginal swabs were exami...

The aim of this research is to study the bactericidal effects copper-polypyrrole composites deposited onto 316L SS modified with silver nanoparticles. antimicrobial properties were evaluated against twenty-four strains Gram-positive and Gram-negative bacteria. Among studied, isolates included reference (E. coli ATCC 25922, E. 0157:H7 EDL 933, S. aureus 25923 L. monocytogenes 7644), as well isol...

ABSTRACT: Essential oils are commonly used to treat minor health problems. In this study the chemical compositions of Lavandula officinalis and Thymus vulgaris were determined by gas chromatography and mass spectrometry. GC/MS analysis of T. vulgaris resulted in thymol as the major oil component where as methyl sulfony exhibited as the most abundant constituent of L. officinalis. The antibacter...

Aqueous extracts and organic solvent extracts of isolated marine cyanobacteria strains were tested for antimicrobial activity against a fungus, Gram-positive and Gram-negative bacteria and for cytotoxic activity against primary rat hepatocytes and HL-60 cells. Antimicrobial activity was based on the agar diffusion assay. Cytotoxic activity was measured by apoptotic cell death scored by cell sur...

results out of 2229 suspected meningitis cases, 255 (11.4%) were detected as positive culture. most of the isolates were gram-positive cocci, which 116 (45.5%) were staphylococcus epidermidis, and 20 (7.8%) identified as streptococcus spp. among gram-negative isolates, escherichia coli and acinetobacter spp., each with 19 isolates (5.9%), were predominant. overall, the most effective antibiotic...

The chemical compositions, antioxidant and antimicrobial properties of fucoidan extracted from Sargassum ilicifolium and S.angustifolium were investigated. The results showed that these seaweeds were characterized by an acceptable level of minerals and proteins. The fatty acid profile was dominated by the palmitic acid, which represents about 37.44±0.01% and 23.05±0.01% of the...

BACKGROUND Clausena anisata belongs to the family Rutaceae, a shrub widely used in West Africa for the treatment of bacterial and fungal infections of the skin including boils, ringworm and eczema. The study was designed to evaluate the antimicrobial activity and phytochemical screening of ethanol leaf extract of C. anisata (CLE). METHOD Antimicrobial activity of CLE was investigated using ag...
