Some medicinal plants are used traditionally in Saudi Arabia to treat many bacterial infections. Three plants, lemongrass (Oymbopogon citrates), lantana (Lantana camara), and wild olive leaves (Olea europaea) were collected, identified, extracted with either hot water or organic solvents (methanol, diethyl ether, ethyl acetate and n-butanol) to investigate their antibacterial activities against...

Characterization and the antibacterial potential of gold (AuNPs) and silver nanoparticle (SNPs) biosynthesized greenly using exopolysaccharides (EPS) and Culture Free Supernatant (CFS) of Wesiella confusa against some multidrug resistance (MDR) E. coli was investigated. The biosynthesized nanoparticles were characterized by UV-visible spectra, Fourier Transfor...

       Cholera toxin B subunit (CtxB) is a homopantameric, nontoxic subunit of cholera toxin that is responsible for its binding to the cell and has been known as a mucosal adjuvant for vaccines that could increase homoral and mocusal immunity response. In this work, the CtxB gene was fused to the StxB gene from Shigella dysenteriae type I a vaccine antigen candidate against t...

results the results showed that the chimeric recombinant protein induced strong humoral response as well as protection against live oral challenges using e. coli o157:h7. conclusions the rit could reduce bacterial shedding effectively. objectives the eae gene encoded intimin protein which is essential for colonization of the mucosa and a/e lesions formation by docking to the tir. materials and ...

this study was carried out to determine the prevalence of foodborne pathogens, escherichia coli, e. coli o157:h7, listeria monocytogenes and campylobacter spp. on slaughtered cattle in isfahan, iran. a total of 203 cattle carcasses were sampled by surface section of neck meat taken immediately after slaughter and analyzed using microbiological examinations. suspected colonies to e. coli o157:h7...
