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.
