Additional recommended knowledge
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.
Pathatrix equipment and procedure
The Pathatrix consist of five independent units for testing allowing five pumpheads. Tubing is then needed for the recirculations process. It is made of silicone rubber. Another part is the capture reagent, this consist of magnetic beads particles that are coated with an antibody specific to the target pathogen.
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. With providing heat in the incubation pots this makes the Pathatrix more sensitive for the detection of the target organism.
To perform a test using the Pathatrix it usually consists of 4 major steps. They include 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. The tub is then connected to form a loop and the magnetic beads are added. Once all this has been done the process in the Pathatrix takes place. The 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. This is done so that colonies cab be viewed within 16 hours. This system should save someone at least 2 days.
