The bacteria can be transmitted easily from animal to animal and in some cases from animal to human. This infection can be found in both dogs and cats, and at any age.
Apudoma is a gastrointestinal tumor found in dogs and cats which secretes peptide hormones -- hormones that play a role in regulating metabolism, growth, development, and tissue function.
