To acquire the TGEV patent, ProdiGene was able to demonstrate the ability of its oral vaccine to overcome a major obstacle for many oral vaccines, the inability of the antigen to survive in the gut thereby neutralizing the body's ability to mount an immune response.
Of the 89 PDCoV-positive samples, 20 samples (22% [11 fecal, 6 intestinal homogenate, 2 fecal swab, and 1 feed]) were negative for TGEV, porcine epidemic diarrhea virus (PEDV), rotavirus A (RVA), rotavirus B (RVB), and rotavirus C (RVC); 69 (78%) PDCoV-positive samples were positive for PEDV, RVA, RVB, or RVC.
We identified positive PDCoV in 20 (22%) samples that were negative for TGEV, PEDV, RVA, RVB, and RVC, but PDCoV co-infections were more common (69 [78%] samples), especially with RVC (52 [58%]).
Protection from TGEV proves that this technology is an innovative method to address animal and human health at a time when fewer therapeutics, such as antibiotics, are available," said Joe Jilka, Ph.
