OBJECTIVES Ciprofloxacin is a broad-spectrum antibiotic widely prescribed in clinical and hospital settings. The emergence of antimicrobial resistance against effective antibiotics is a global issue. The objective of study is the surveillance of ciprofloxacin against common pathogens. METHODS To investigate the present status of antimicrobial resistance against ciprofloxacin, five hundred and...

The methanolic leaf extract of Newbouldia laevis was subjected to preliminary phytochemical screening and in-vitro antimicrobial tests. The extract revealed the presence of flavonoids, tannins, terpenes, steroidal and cardiac glycosides. The antimicrobial activity of the plant extract was assayed by the agar plate disc diffusion and nutrient broth dilution techniques. Test microorganisms were P...

Bactericidal activity of crude extracts from lichen Ramalina pacifica were screened against 20 clinical pathogenic strains isolated from different infectious sources which belong to Pseudomonas aeruginosa, Klebsiella pneumonia, Salmonella typhi, Salmonella paratyphi, Echerichia coli, and Staphylococcus aureus. The minimal inhibitory concentration of petroleum ether extract and ethanol extract w...

This study aimed to determine the antibacterial activity and toxicity of methanol hexane extracts Halymenia durvillei red seaweed which were found abundantly in Kayangan island, South Sulawesi. The crude extract was tested against five gram-negative bacteria, namely Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa, Aeromonas hydrophila, Vibrio harveyi at a dose 200 g/disk. Extract on ...

The phytochemical analysis of the medicinal plants are important and have commercial interest in both research institutes pharmaceutical companies for manufacturing new drugs treatment various diseases. present study was aimed to investigate preliminary screening seeds Syzygium cumini belonging family Myrtaceae. results revealed presence medicinally constituents ethyl acetate methanol extracts ...

The reaction of benzil, 1-alkyl-2-arylethanediamine dihydrochloride and sodium acetate trihydrate gave the target molecule dihydropyrazine derivatives 30-34. The compounds have been characterized on the basis of their FT-IR, 1H NMR and 13C NMR spectroscopies. All the compounds are screened for their antibacterial activity against Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aerugin...

the antimicrobial activity of methanolic extracts from different parts of 11 indigenous wild plantspecies used in traditional medicines of iran were tested against nine species of microorganisms: escherichiacoli, staphylococcus aureus, staphylococcus epidermis, pseudomonas aeruginosa, klebsiella pneumoniae,salmonella typhi, bacillus subtilis, aspergillus niger and candida albicans. the antimicr...

Trianthema decandra L. root and root callus extracts of different solvents viz., petroleum ether, chloroform, ethyl acetate and ethanol were tested against both Gram positive and Gram negative bacteria and also against Fusarium spp. Root callus extract of chloroform and ethanol showed significant activity against Bacillus subtilis, B. cereus. Staphylococcus aureus, Staph. epidermis and also aga...

Background: The emergence of antimicrobial resistance results in morbidities and mortalities associated with many bacterial infections is a major concerning issue front the healthcare system. As part competitive adaptive strategy for its growth, gram-positive bacteria like Bacillus subtilis produce peptides; bacteriocins. These peptides protect other species. Objectives: To counter resistance, ...

Objective(s): A large ratio of surface to volume of nanoparticles in comparison with bulk ones, will increase the cell penetration and therefore their toxicity. Materials and Methods: Chemical precipitation method was used in order to synthesis of ZnS:Ag quantum dots. Their Physical properties and characteristics were assessed by X-ray diffraction, Ultra Violet-Visible Spectrophotometer, Transm...
