Salmonella viruses as biocides in the food industry
Lead Research Organisation:
University of East Anglia
Department Name: Graduate Office
Abstract
A safe food supply for humans and animals requires innovative approaches to exclude bacterial pathogens such as Salmonella from food and feed. The use of naturally occurring bacterial viruses called bacteriophage to kill bacteria in the food chain and processing environments is an exciting area of innovation. Rationale design and implementation of such approaches require scientific knowledge of the genetic diversity of the bacterial host and bacteriophage, to identify potential mechanisms of resistance. At the Quadram Institute Bioscience we are investigating the genomic diversity of bacterial pathogens in the food chain, and this project will integrate with these efforts by discovering and analysing bacteriophage that can be used to eradicate these pathogens from food and food processing environments. In this project you will learn to use cutting edge whole genome sequencing, bioinformatic and molecular microbiology technologies to investigate the mechanisms of killing and resistance of Salmonella by novel bacteriophage. In partnership with a leading food processing company, intervention strategies aimed at excluding Salmonella from food will be developed and tested in a model factory in the lab.

Description | We have identified, purified and sequenced a collection of Bacteriophages (Viruses which Infect Bacteria) which are capable of killing Salmonella, which are of potential use in food and feed processing environments. Through the use of functional genomic approaches, we have identified the Phages host range (How many Bacteria they kill), bacterial targets and identified mechanisms of resistance to the bacteriophages. Using this information, it has allowed us to formulate combinations of bacteriophages which work synergistically together, which make them much more effective at killing their bacterial target. This innovative approach will help design better phage cocktails which have applications in both biotechnology, food safety and phage therapy. |
Exploitation Route | Bacteriophages Isolated in this project and a resource which will be useful to others. In addition, the rich phenotypic data generated will be critical to their appropriate use for many potential applications. It is hoped that this could be used as a proof of concept, demonstrating that rich phentypic data relating to Host Range, Genomics, and Resistance can better inform the use of bacteriophages and improve the efficacy in many applications. |

Description | Findings of this award can have huge impact on the food production sector. There is a growing need for novel methods to exclude pathogens from ready to eat products where no intervention methods are in place. The outcomes of the award can help inform the food production industry that bacteriophages are a potential method to help prevent contamination within the food production environment and the food product. This can help improve quality of life to reduce infections to the public and also has economic impact to help prevent infections, reducing the economic burden of food bourne disease. |
