Research ArticleOpen accessIn the abstractPOTENCY OF HONEY AS ANTIBACTERIAL AGENT AGAINST MULTIPLE ANTIBIOTIC RESISTANT PATHOGENS EVALUATED BY DIFFERENT METHODSMohamed Mustafa Aween, Zaiton Hassan, Nur Huda-Faujani et al.Honey is rich with complex natural components which could be useful as antibacterial agents or as preservative. Honey contains high concentration of sugars, low amount of water, high osmolality and often dark colour which influence its antibacterial activity. Disc diffusion, well method, micro dilution assay are methods commonly used to determine the antibacterial activity of honey. In this study, microtiter … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 1 Dec 2014 · 6,570 accessesView PDFCite

Then the ethanol extract of lotus leaves were further … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 18 Nov 2014 · 10,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractGRAPHENE OXIDE AS ANTIMICROBIAL AGAINST TWO GRAM-POSITIVE AND TWO GRAM-NEGATIVE BACTERIA IN ADDITION TO ONE FUNGUSRoda F. Al-Thani, Noorunnisa Khanam Patan, Mariam A. Al-MaadeedGraphene based materials have wide potential applications in biology, biomedical, agriculture environmental and biotechnology. Graphene Oxide (GO) is one of those materials and has a promising substance as antimicrobial agents. GO in this study was prepared by a modified Hummers method and was characterized by different techniques for confirmation of formation of GO. To study the antimicrobial activities of GO, … …OnLine Journal of Biological Sciences, Vol. 14, Issue 3 · 14 Oct 2014 · 9,246 accessesView PDFCite

Research ArticleOpen accessIn the abstractPHENOTYPING, VIRULENCE CHARACTERISTICS OF AEROMONAS SPECIES AND THE EFFECTS OF ESSENTIAL PLANT OILS AS ANTIMICROBIAL AGENTS AGAINST PATHOGENIC ISOLATES FROM DIFFERENT SOURCESAhmed M.A. Mansour, Hoda M. Zaki, Nibal A. Hassan, Nihad A.M. El-NasharAeromonas species are increasingly recognized as enteric pathogens. Faecal samples from 20 cow, 45 sheep; 60 goat and 60 camels were examined for the presence of Aeromonas species, which was also sought in the available drinking water (55 well water and 52 drinking chlorinated tap water were also examined). Aeromonas species was isolated more frequently from goats (21.7%) than from … …American Journal of Infectious Diseases, Vol. 10, Issue 1 · 18 Jan 2014 · 8,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractMOLECULAR CHARACTERIZATION AND IMMUNOPROTECTIVE ACTIVITY OF CAPSULAR POLYSACCHARIDE OF KLEBSIELLA PNEUMONIAE ISOLATED FROM FARM ANIMALS AT TAIF GOVERNORATEAhmed M.A. Mansour, Hoda M. Zaki, Nibal A. Hassan, Abdulrahman A. Al-HumianyKlebsiella pneumoniae is a Gram-negative enterobacterium that has historically been and currently remains, a significant cause of human disease and several kinds of infections in animals. In the present work, trials for the isolation of Klebsiella pneumoniae from diseased and apparently healthy farm animals (cows, sheep, goats and camels) were done for recognition of Klebsiella pneumoniae subspecies.

Research ArticleOpen accessIn the abstractIsolation of the Antimicrobial Cyclic Peptide Subtilosin a from a Gut-Associated Bacillus subtilis StrainGhislain Schyns, Claudia R. Serra, Adriano O. Henriques et al.The endospore-forming Bacillus subtilis has been used as probiotics over the last 50 years. However, little is known on how Bacillus spp act in the gut compared to other well-characterized probiotics such as lactic acid bacteria. It is believed that the competitive exclusion of pathogens results from different mode of action notably the production of antimicrobial compounds such as bacteriocins. … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 7,682 accessesView PDFCite
