Question of the Day

A farmer recently purchased a sheep from a salebarn. The sheep soon became ill, with progressive depression, lethargy, and inappetance.
He had respiratory problems, breathing hard with abdominal effort, and died after three days with a frothy nasal discharge just prior to death.
At necropsy, the lungs had the appearance shown below.
What was the most likely cause of death?
