Scarred pitted kidney
-
Focal, depressed areas of the kidney are typical of infection with Encephalitozoon cuniculi. The disease causes granulomatous lesions in the kidneys that become pitted and scarred with fibrotic areas

Spleen in a rabbit with RHD2
-
The spleen must be found during a post-mortem examination. Lifting the stomach and reflecting it dorsolaterally the spleen can be found, attached to the stomach by the lesser omentum. In this case it is at least double the size it should be. This is a sign of RHD.

White spots in liver
-
Several disease can cause white spots in the liver. Hepatic coccidiosis is the most likely cause.

Eimeria steidae

Hepatic coccidia obtained by a firmly-made impression with a microscope slide onto the cut surface of an affected liver. The slide was stained with RapidDiff2. The rabbit had died from RHDV2 which made an unavoidable preponderance of erythrocytes even with careful preparation (blotting) of the liver before applying the slide. Three slides were made and this, the third, was the only slide with coccidia. Success with this technique requires careful blotting of the cut surface and some pressure on the sides of the liver so that coccidia are squeezed out of the affected bile ducts.

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.

Eimeria steidae

The freshly cut section of liver of a young male wild rabbit that died from RDH2, shows several areas of fibrosis involving the bile ducts. There is also a normal bile duct running across the section. This appearance is very suggestive of hepatic coccidiosis. Cytology can be used to confirm the presence of coccidial oocysts. Histology will also show the oocysts as well as showing the typical changes produced by RHD. A pcr test for rhd/rhd2 is required to confirm the presence of this viral disease.
