Plain-English summary
Two Rottweiler puppies from the same litter developed severe diarrhea starting at 6.5 weeks old. One puppy was put to sleep at 14 weeks due to liver damage caused by a newly identified protozoan parasite. The second puppy was euthanized at 10 weeks after showing signs of severe infection in the lymph nodes, which were filled with another type of parasite. Unfortunately, both puppies did not survive, highlighting the seriousness of these infections.

Abstract
Two of 8 littermate Rottweiler dogs developed persistent diarrhea at 6.5 weeks of age. Dog 1 was euthanatized at 14 weeks of age and had hepatitis characterized by necrosis and mixed leukocyte infiltrations in association with a previously unrecognized Sarcocystis-like protozoon. The organism was free in the hepatocyte cytoplasm without a parasitophorous vacuole, had divided by schizogony, and stained with anti-Sarcocystis serum, but did not stain with anti-Toxoplasma gondii or anti-Neospora caninum serum in an immunohistochemical test. Dog 2 was euthanatized at 10 weeks of age. This dog had large necrotic, hemorrhagic mesenteric lymph nodes. Numerous T gondii tachyzoites were observed in association with these lesions. The organism divided by endodyogeny and stained specifically with anti-T gondii serum.
