2. Keeping deer with cattle, sheep, or goats

3. Group housing fawns on dirt or other surface that cannot be easily cleaned.

4. Reusing needles from one deer to the next.

-How serious is Trueperella pyogenes?

It usually causes a localized infection that is easy to manage if properly diagnosed and properly treated. If it is not treated early or if it gets into the lungs or other organs, it can be life-threatening.
