Research ArticleOpen accessIn the abstractBiosynthesis of Zinc Oxide Nanoparticles and Assay of Antibacterial ActivityEmad J. Ibrahem, Karkaz M. Thalij, Mahmood K. Saleh, Amin S. BadawyIn this study Out of 280 urinary tract infections samples, 212(75.7%) bacterial isolates were recovered. Based on, morphological, cultural and biochemical testes, further, confirmed the results by VITEK 2 System there were 54 (30.2%) of gram positive whereas the 158 (69.8%) of gram negative. The bacterial isolates were distributed as Escherichia coli followed by Klebsiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 2 · 3 Apr 2017 · 8,880 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAntibacterial and Anti-Quorum Sensing Activities of Selected Italian Honeys against Antibiotic-Resistant PathogensMarco Fidaleo, Roberto Lavecchia, Antonio ZuorroThree nectar honeys (eucalyptus, thyme and forest) and two honeydew honeys (fir and Metcalfa) from Italy were tested for their antibacterial activity against pathogens commonly associated with wound and burn infections, including Methicillin-Resistant Staphylococcus Aureus (MRSA), methicillin-resistant Staphylococcus epidermidis (MRSE) and Vancomycin-Resistant Enterococcus Faecalis (VREF). All honeys showed bactericidal activity against the microorganisms used, with honeydew honeys being the most … …OnLine Journal of Biological Sciences, Vol. 15, Issue 4 · 27 Oct 2015 · 7,050 accessesView PDF Cite

EditorialOpen accessIn the abstractThe Food Additives Nitrite and Nitrate and Microbiological Safety of Food ProductsStefanie Müller-Herbst, Anna Mühlig, Jan Kabisch et al.In Germany, raw sausages are typically produced according to a technology referred to as hurdle technology (Leistner, 2000). The combination of several stressful conditions should successfully inhibit growth and survival of pathogenic bacteria, which can be regularly found in raw pork or beef material (Mataragas et al., 2008; Rhoades et al., 2009). Hurdles applied during raw sausage fermentation are the … …Current Research in Microbiology, Vol. 6, Issue 1 · 29 Jun 2015 · 10,378 accessesView PDF Cite

EditorialOpen accessIn the abstractAntibacterial Quorum-Sensing Molecules as Long Lasting Antibacterial DrugsAnanya Pavuluri, Yan Zhang, Shanzhi WangAntibacterial quorum-sensing molecules are a new type of antibacterial reagent that blocks bacterial communications and dampens virulence. These molecules are proposed to tackle the roots of drug resistance and to be long lasting, although more research should be done toward the effectiveness and resistance of these drugs. …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 26 Jan 2015 · 6,925 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of Different Drugs in Down-Regulation of Efflux Pump Genes expression in Methicillin-Resistant Staphylococcus aureus StrainsManu Chaudhary, Santosh Kumar Patnaik, Anurag PayasiAntimicrobial resistance caused by efflux systems is not widely studied in Staphylococcus aureus. In the present study, prevalence of NorA and NorB efflux pumps was studied in thirteen Methicillin-Resistant Staphylococcus aureus (MRSA) strains using a pair of primers with Polymerase Chain Reaction (PCR). Antibiotic susceptibility study in NorA and NorB efflux positive isolates was carried out according to the Clinical … …American Journal of Infectious Diseases, Vol. 10, Issue 4 · 7 Jan 2015 · 7,451 accessesView PDF Cite

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 · 6,564 accessesView PDF Cite
