Two clerodane diterpenoids, Bafoudiosbulbins A 1, and B 2, together with five known compounds: tetracosanoic acid, 1-(tetracosanoyl)-glycerol, trans-tetracosanylferulate, beta-sitosterol and 3-O-beta-D-glucopyranosyl-beta-sitosterol were isolated from the tubers of Dioscorea bulbifera L. var sativa. Their structures were established by spectroscopic methods (1D and 2D-NMR, MS) and X-ray crystal...

OBJECTIVE To determine the occurrence of bacterial pathogens responsible for diarrhea and to engender information regarding the effectiveness of commonly used antibiotic against diarrhea. METHODS This cross-sectional study was conducted between April and July 2014. Samples were collected from the Divisional Headquarter and Allied Hospital, Faisalabad, Pakistan. The differential and selective ...

To the Editor—Field investigations in the People’s Republic of China to determine the protective efficacy of typhoid Vi polysaccharide vaccine (Vi vaccine) were done among students attending a middle school [1]. Vi vaccine was offered to students even during an outbreak of typhoid fever. The efficacy was 73% among those immunized before the outbreak and 71% among vaccine recipients during the o...

Antimicrobial activity of the roots of Eranthemum roseum (Vahl) R.Br. (Dasmuli), were tested against different bacteria (including Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Shigella sonnei, Klebsiella pneumoniae, Salmonella typhi, Proteus vulgaris, Pseudomonas aeruginosa) and fungi (such as Candida albicans and Aspergillus niger) by cup plate diffusion method. Minimal Inhibito...

Blood, stool and urine samples were collected from 100 patients diagnosed as having typhoid in 5 hospitals in Akwa Ibom State and analyzed for the presence of Salmonella species and other bacteria. Of the 100 blood samples screened, 55 (55%) were positive with the Widal test and 39 (39%) were positive on blood culture. Thirteen (14.1%) out of 92 urine samples were positive for bacterial growth,...

Chemical precipitation method was used in order to synthesize CdSe:Ag quantum dots (2-3 nm). Their Physical properties and characteristics were assessed by X-ray diffraction, ultra violet-visible spectrophotometer and TEM (Transmission Electron Microscope) and it was shown that the obtained CdSe:Ag quantum dots are cubic with high-quality. Antibacterial effects of CdSe:Ag nanoparticles against ...

The in vitro antimicrobial activities of the whole plant extract (ethanolic-CEE) of Chrozophora senegalensis and its fractions (ethyl acetate-EAA, n-butanol-NBE, aqueous-AQE) were assayed using the agar plate diffusion and nutrient broth dilution methods. Test microorganisms were Bacillus subtilis (NCTC 8326 B76), Escherichia coli (ATCC 11775), Pseudomonas aeruginosa (ATCC 10145), Staphylococcu...
