Subsequent Events [Abstract]
SUBSEQUENT EVENTS	19. SUBSEQUENT EVENTS We have evaluated subsequent events through the time of filing on August 13, 2018, the date we have issued this Quarterly Report on Form 10-Q. As of such date, with the exception of the transaction described in the next paragraph, there were no material, reportable subsequent events. During July 2018, we sold certain non-core assets for $700,000 to TCS Biosciences Ltd of Buckingham, United Kingdom. The sale includes the cell line and intellectual property underlying our diagnostic test to detect the presence of Cryptosporidium in drinking water. A payment of $250,000 was received up front, and the remaining $450,000 is due in two payments during the second half of 2019. We retained the rights to all animal health, diagnostic, feed and nutritional applications of this technology. This agreement also includes a purchase order for product worth approximately $125,000 that may be sold to TCS during the first quarter of 2019.
