Many adult females developed a swelling of their lower jaws, it wouldn't typically result in death but was fairly common to see. Samson taught employees that an incision with a knife could be made on these animals jaws to drain the fluid and puss buildup inside the mass.

There were respiratory infections that would cause a thick mucus to clog up animals throats and suffocate them slowly. The thick mucus could be removed, but would build up again overnight. The respiratory infection would often result in death and seemed contagious to other animals.

Some animals would develop little red pimple like blisters all over their bodies, and was contagious to other animals. When an animal would develop these, it would mean that they would likely die within the month. Out of all the animals that got these blisters, only a small number actually survived. 

The only thing used to treat them was an iodine bath, which wasn't enough to combat whatever was going on inside their bodies.

There were parasites in breeding males that would actively be paired with females, even though they had parasites.

Due to no quarantine process being present within Samson Pruitt's collection, there is no telling where these issues originated from. The fact that Samson was willing to sell animals out of the same building that all of these issues were going on in speaks volumes to his ethics and business practices. It is always a good practice to quarantine new animals, no matter how large or small your collection is. 

But when you have a collection the size of Samson's it is especially important so that such a large quantity of animals don't suffer for the negligence of one.
