Yersiniosis
Occasionally rabbits may be infected with Yersinia pseudotuberculosis.  During life, it causes vague clinical signs of anorexia and weight loss. At post-mortem examination , numerous white foci  can be observed on the intestine, especially in the appendix ( white arrow) and sacculus rotundus (yellow arrow). Foci may also be seen in the spleen.
