By Dr Duncan Houston BVSc – Salmonellosis is a bacterial disease caused by *Salmonella* species that can infect hamsters, causing digestive illness, systemic spread, and posing zoonotic risk. In this comprehensive 2025 guide, we’ll cover causes, symptoms, diagnosis, treatment, hygiene protocols, and prevention—ensuring both your pet and household stay healthy. Stay informed, stay safe! 🌿

📘 What Is Salmonellosis?

Salmonellosis is an infectious disease caused by bacteria in the genus *Salmonella*. Hamsters can acquire it through contaminated food, water, bedding, or infected fomites. Infection affects the gut, but can lead to systemic illness and poses a serious zoonotic threat.
