MobileAir Xtractor 400 (MAX400)

The MAX400 is a patented, revolutionary air sampling system used by producers and researchers to monitor airborne pathogens potentially threatening their operations. The system has successfully been used to detect Influenza, Porcine Reproductive and Respiratory Syndrome Virus, and Mycoplasma hypopneumoniaewithin operations, as well as at distances of at least 3 miles from affected operations (Corzo et al., 2013a; Corzo et al.,2013b; Dee et al., 2009; Otake et al., 2010).

Airborne dissemination of pathogens is a significant risk to producers, and the MAX400 is designed to assist in the identification of these risks. Industry experts using the device have provided "veterinarians and producers with proof that longdistance airborne transport of economically significant pathogens of swine is possible." (Dee et al., 2009). In controlled experiments, the MAX400 "proved to be an analytically sensitive method for detecting airborneinfluenza virus...at very low aerosolized concentrations of 101 TCID50/ml."(Corzoet al., 2013b).

Regional aerosol collection, detection and elimination of these pathogens are critical elements of a successful eradication program - the MAX400 is the first step in establishing an early warning system.

The MAX400 provides animal producers with a precise system for the collection of samples leading to the early detection of airborne pathogens. Once collected, samples are submitted to a diagnostic lab for analysis using well-defined, PCR based techniques. This is the first step to disease eradication and significant operating cost savings. Early detection of airborne infectious disease will serve as a valuable function in helping animal producers reach new levels of productivity in the 21st century.
