Pathatrix

Pathatrix is an immuno-capture method whose feature allows the entire sample plus pre-enriched sample to be recirculated over antibody-coated paramagnetic beads. It can specifically purify and detect pathogens directly from food samples within hours. It is also used to improve the performance of other rapid methods such as PCR, lateral flow, ELISA and chromgenic media by reducing or eliminating the need for lengthy enrichment and/or selective enrichment steps. The Pathatrix is useful in pathogen labs that would be running food samples and looking for foodborne diseases.

The Pathatrix was developed due to the foodborne outbreaks occurring. If infected with a foodborne disease it can be fatal to some individuals such as, very young or elderly. The Pathatrix is a rapid test method that helps in testing for microorganisms quickly. There are some foods that the Pathatrix is not useful for such as pre-pared sandwiches.

The Pathatrix will selectively bind and purify the target organism from a comprehensive range of complex food matrices. The Pathatrix is the only microbial detection system that allows for the entire sample to be analyzed.

Pathatrix procedure
To perform a test using Pathatrix there are 4 major steps including sample preparation, pre-incubation, placing the sample in the Pathatrix, and washing and elution.

Once the food samples are ready they are placed in the five independent incubation pots providing heat that makes the Pathatrix more sensitive for the detection of the target organism. Tubing, made of silicone rubber, is then connected to form a loop. Finally magnetic beads particles, coated with an antibody specific to the target pathogen, are added.

The whole process runs for 180 minutes at a temperature between 30-37 degrees Celsius. After the incubation has taken place the target organism, now captured by the reagent, are now retained on the magnetic while unwanted debris is taken away. During the capture phase the microorganisms are removed from the system and further processed, otherwise colonies can be seen within as little as 16 hours.
