Veterinary vaccines are subjected to a safety testing using laboratory animals via intraperitoneal injection per batch. From April 2010 to March 2011, 7 guinea pigs in 4 batch tests exhibited unrecoverable weight loss and/or were found dead. Six guinea pigs had developed intussusception, whereas another one had developed an intestinal obstruction consequent to adhesion. A histopathology revealed that these lesions were associated with inflammatory foci. Other animals than the 7 guinea pig also developed similar inflammatory foci but did not develop bowel disorders. In the retesting of these batches, animals did not exhibited clinical signs, though inflammatory foci were detected. The clinical signs, detected in the primary test, might be due to bowel disorders secondary to an inflammatory response, rather than toxicity.
