Helicobacter Gastritis
What is it?
Many ferrets carry the stomach bacterium Helicobacter mustelae. Under stress or with other illnesses, it can cause stomach inflammation and ulcers.
What signs should I watch for?
Signs to watch for include poor appetite, weight loss; vomiting; dark, tarry stools; grinding teeth or drooling (signs of nausea); and lethargy.
How is it diagnosed and treated?
Diagnosis is often based on signs and response to treatment; biopsy is definitive. Treatment combines multiple antibiotics with stomach-protective medication, plus nutritional support.
Can it be prevented, and what's the outlook?
Reducing stress and treating promptly usually improves the outlook, though relapses can occur.
