Johne's Disease Test

TREK Diagnostic Systems, Inc. introduces ESP para-JEM system, the firstfully-automated method available for routine detection of M. avium ssp.paratuberculosis, the causative agent of Johne's disease. Johne's diseaseis a progressive, wasting disease of cattle and other ruminants, costingthe U.S. beef and dairy industries up to $200 million annually from animallosses, the company says. The ESP para-JEM system automates standard culturemethods, providing fast detection with continuous, automatic specimen monitoring.Positive report times are available two to three weeks earlier than conventionalculture methods, which allows for reliable semi-quantitation of high, medium,and low shedders, the company says. Negative culture reports are shortenedfrom the current standard of 12 weeks to just six weeks. Accuracy is improvedby 15 percent, when compared to the standard culture method, the companysays. The ESP para-JEM system consists of the para-JEM liquid broth andreagents, which are specially formulated to provide an optimal environmentfor recovery and detection of M. avium ssp. paratuberculosis, and the ESPCulture System II instrument, which incubates and continuously monitorsspecimens using a unique, non-radiometric, pressure sensing detection system.
