Plain-English summary

A 1-year-old female dog died suddenly and was found to have numerous grey-tan nodules in her lungs, brain, and lymph nodes. Upon examination, the cause was identified as infections from two parasites: Toxoplasma gondii, which caused significant tissue damage, and Hepatozoon canis, which was also present in her lymph nodes and spleen. Unfortunately, despite the findings, the dog did not survive. This case highlights the serious impact of these infections on a young dog's health.

Abstract

A female 1-year-old dog died suddenly and was submitted for necropsy. Numerous grey-tan-colored nodules were seen in the lungs, brain and lymph nodes. Microscopically, the predominant lesion was necrosis associated with numerous Toxoplasma gondii tachyzoites. The parasites reacted positively with anti-T. gondii serum in an immunohistochemical test. Schizonts of Hepatozoon canis were seen in sections of lymph nodes and the spleen.
