The PhOx
technology addresses an urgent need for truly rapid and affordable detection of
pathogenic bacterial contamination in fresh and processed food with higher
sensitivity and specificity than current technologies. Most current methods of detecting bacterial
contamination take at least 8 hours and up to 10 days. Our technology is able to conclusively detect the presence of
bacteria in fresh food in one to five hours, and potentially faster. The PhOx system is able to be completely automated, requiring no handling between loading and removing samples for testing. Full automation opens up possibilities of offering in-line testing, lowering sample management costs. The PhOx technology is considerably more sensitive and clearly more rapid than current product offerings. Our system is flexible and can be configured to identify the presence of live bacteria in a very wide range of different substances. The significant reduction in time and the increase in sensitivity allows companies to respond to contamination quickly, eliminating expenses and reducing risks associated with slow testing times. The
major difference between PhOx Diagnostics’ detection method and other rapid
methods lies is what is being detected. Current rapid methods detect pathogens
produced by bacteria contaminating a sample. However, there must be a high level of
contamination to generate pathogens which means that prior to being able to use their rapid systems the sample must spend a period of time (8-48 hours) during which the sample is enriched, promoting rapid growth of the contaminating bacteria. By contrast, the PhOx system
detects the presence of live bacteria by measuring oxygen
depletion curves in the sample. Since all bacteria must consume oxygen in order to live, and since each type of bacteria has an individual oxygen consumption rate, this is a very effective and simple way to detect live bacteria. Enrichment
prior to testing is not required. |
