Gram-positive pathogens are a significant cause of morbidity and mortality in both community and health care settings. Glycopeptides have traditionally been the antibiotics of choice for multiresistant Gram-positive pathogens but there are problems with their use, including the emergence of glycopeptide-resistant strains, tissue penetration, and achieving and monitoring adequate serum levels. N...

Tectona grandis L. (Teak) is one of the commercial plants which often used in Southeast Asia. Globally, total area planted teaks reaches 3 million hectares, with about 31% land located Indonesia. Preliminary phytochemistry showed bioactive constituents as alkaloids, tannins, flavonoids and phenolic compounds. Isolation characterization by several methods were reported for quantifying secondary ...

The sensitivity of bacteria to the marine neurotoxins, brevetoxins, produced by the dinoflagellate Karenia brevis and raphidophytes Chattonella spp. remains an open question. We investigated the bacteriocidal effects of brevetoxin (PbTx-2) on the abundance and community composition of natural microbial communities by adding it to microbes from three coastal marine locations that have varying de...

Background and Aims: Campanula tomentosa Lam. Verbascum mykales Bornm. are endemic species in Turkey. Extracts of these plants contain important natural compounds such as flavonoids, saponins tannins. This study investigates the antimicrobial effects leaf extracts C. V. against some bacteria yeasts. Materials Methods: Leaves plant samples were air-dried ground into powder. Five solvents (ethyl ...

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 <...
