Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Listeria monocytogenes belongs to one of four severe food-borne pathogens issued by World Health Organization. It has the ability to form biofihns on food-processing surfaces, potentially leading to food product contamination. In order to examine the effection of PrfA on biofilm formation in L. monocytogenes, the wild strain EGD (LM), the virulence genes prfA deletion mutant strain ΔprfA, Listeria innocua (LI) and recombinated Listeria innocua strain contained pERL3-pr£4* (LI-pERL3-PrfA*) were compared to examine their biofilm formation abilities in BHI media at 37°C, our results indicated that deletion of prfA reduced the ability of L. monocytogenes to form rigid biofim structure, however, no impact was observed on the L. innocua biofilm formation.
