Foodborne illness is a global burden that impacts a country politically, economically and
socio-economically. The severity of the burden can be unmeasurable as foodborne illness
is often an underestimated problem. In order to enlighten the burden, appropriate food
safety control measures should be taken. This study aimed to optimize a multiplex
Polymerase Chain Reaction (mPCR) detection method to identify foodborne pathogens
simultaneously. Six foodborne pathogens namely, Salmonella spp., Escherichia coli O157,
Vibrio parahaemolyticus, Vibrio cholerae, Listeria monocytogenes and Campylobacter
spp., were targeted in the mPCR detection method. Each mPCR parameter was tested and
the outcome was analysed to obtain a successful mPCR protocol to detect the targeted
foodborne pathogens. The amplified PCR products showed that the optimized mPCR
protocol will be a potential rapid diagnostic tool in foodborne pathogen detection.
Bacteriophages are ubiquitous in our world, mainly in the oceans, soil, the water and food
we consume. They can be used efficiently in modern biotechnology, as well as alternatives
to antibiotics for many antibiotic resistant bacterial strains. Phages can be used as vehicles
for vaccines both DNA and protein, for the detection of pathogenic bacterial strain, as biocontrol
agents in agriculture and food industry. This review outlines the properties as well
as the influence of different external physical and chemical factors like temperature and
acidity on phage persistence. A better understanding of the complex problem of phage
sensitivity to external factors may be useful for other researchers working with phages.
Furthermore, the applications of bacteriophages were described in this paper as well.
