Case Study 3

Dead Cattle, bloated, with epistaxis

Wrong Answer!

Question 5 of 8

It is common practice in cases of domestic animal disease to conduct a post mortem examination. Will you do a post mortem exam on one or more of these cattle? P>

A. Yes
Opening a carcass infected with B. anthracis exposes the organism to oxygen in the air and induces sporulation. B. anthracis will sporulate only under well aerated conditions. The high levels of CO2 inside the carcass prevents sporulation.

Spores are very resistant to environmental conditions and can persist for many years if released in the environment. Therefore, an autopsy should not be performed. The carcasses should be burned or buried with lime.
