Refines O 157 Evolutionary Model 1 Escherichia coli serotype O 55 : H 7 diversity supports parallel acquisition of bacteriophage 1 at Shiga toxin phage insertion sites during evolution of the O 157 : H 7 lineage

Survey of the contamination of foodstuffs from animal origin ( beef , pork , chicken , fish ) by shiga toxin producing Escherichia coli serotype O 157 : H 7 in Belgium from 1999 to 2003

Seasonal change and fate of coliphages infected to Escherichia coli O157:H7 in a wastewater treatment plant.

Seasonal change of virulent phage infected to two E. coli O157:H7 strains (O:157-phage) in the influent of a domestic wastewater treatment plant in the central part of Japan and fate of O:157-phage in the plant were monitored almost monthly from March 2001 to February 2002. Coliphage infected to nonpathogenic E. coli O157:H7 ATCC43888 (43888-phage) was detected for 1 year. On the other hand, ph...

Inhibitory Effect of Nano-gel/Emulsion of Chitosan Coating Incorporated with Ziziphora Clinopodioides Essential Oil and Nisin on Escherichia Coli O157:H7 Inoculated in Beef at Cold Storage Condition

Introduction: This study was conducted to evaluate the influence of chitosan Nano-gel/emulsion coating functionalized by Ziziphora clinopodioides essential oil (ZCEO) and nisin on growth inhibition of Escherichia coli O157: H7 inoculated in beef samples during 16 days in cold storage condition (4˚C). Methods: Beef sample ...

Effect of alginate coatings containing Zataria Multiflora Boiss essential oil in forms of coarse emulsion and Nano-emulsion on inoculated Escherichia coli O157:H7 in beef fillets

The present study was carried out to compare the inhibitory effect of alginate coatings containing Zataria Multiflora Boiss essential oil (ZMEO) in two forms of coarse emulsion and Nano-emulsion on the growth of inoculated Escherichia coli O157:H7in beef fillet during 16 days of refrigeration (4 C °). Accordingly, alginate solutions (3%) with different co...
