🌿 Tularemia in Hamsters: A Vet’s 2025 Guide by Dr Duncan Houston BVSc 🛡️

By Dr Duncan Houston BVSc – Though rare, tularemia—a serious infection caused by *Francisella tularensis*—can affect hamsters. This 2025 guide explains what it is, how it presents, why it’s a zoonotic hazard, and why euthanasia and strict hygiene are essential. If you keep hamsters, knowing these facts could protect your pet and family. 💚🐹

🔬 What Is Tularemia?

Tularemia (rabbit fever) is caused by the bacterium *Francisella tularensis*. It can infect rodents, rabbits, and humans, often via tick/mite bites or contact with infected animals. In hamsters, infection is rare but can be rapidly fatal—often killing within 48 hours of onset. :contentReference[oaicite:3]{index=3}

⚠️ How Do Hamsters Get It?

• Tick or mite bites that transmit the bacterium. :contentReference[oaicite:4]{index=4}
• Potential exposure to infected wildlife, bedding, or during shipment. :contentReference[oaicite:5]{index=5}
• Contamination via infected fleas, lice, or mites. :contentReference[oaicite:6]{index=6}

🩺 Clinical Signs in Hamsters

• Depression and dull appearance, rough coat, reduced appetite. :contentReference[oaicite:7]{index=7}
• Sudden death—signs often appear too late. :contentReference[oaicite:8]{index=8}
• Post-mortem: enlarged liver, spleen, lymph nodes, possible bleeding. :contentReference[oaicite:9]{index=9}

🔍 Diagnosis & Testing

• Often confirmed post-mortem via necropsy. :contentReference[oaicite:10]{index=10}
• Cultures or PCR may detect *F. tularensis* in organ tissue. :contentReference[oaicite:11]{index=11}
• X‑rays may show enlarged liver/spleen if done pre-death. :contentReference[oaicite:12]{index=12}

🚑 Treatment: It Doesn’t Exist for Hamsters

Unlike humans, antibiotics are not effective in hamsters. The disease progresses too rapidly, and euthanasia is often the only humane and safe option for infected or exposed animals. :contentReference[oaicite:13]{index=13}

🧼 Zoonotic Risk: A Serious Concern

• Humans can catch tularemia from hamster bites or contact with infected tissues or bedding. :contentReference[oaicite:14]{index=14}
• A documented case in Colorado: a 3-year-old contracted tularemia after a hamster bite. :contentReference[oaicite:15]{index=15}
• Human forms vary—ulceroglandular, glandular, pneumonic—with fever, lymphadenopathy, and possible ulceration. :contentReference[oaicite:16]{index=16}

🧨 Human Treatment—But Not for Pets

Humans recover with prompt antibiotic therapy (streptomycin, gentamicin, doxycycline, ciprofloxacin). Duration runs 10–21 days. :contentReference[oaicite:17]{index=17}

🛡️ Prevention & Hygiene Measures

• Avoid tick or mite exposure; use vet-approved acaricides on habitat if outdoor exposure. :contentReference[oaicite:18]{index=18}
• Quarantine new hamsters and monitor them for at least 2 weeks. :contentReference[oaicite:19]{index=19}
• Use gloves when handling sick hamsters or any bedding—double-bag waste. :contentReference[oaicite:20]{index=20}
• Thoroughly disinfect all habitats with bleach or appropriate virucidal agents. :contentReference[oaicite:21]{index=21}
• Dispose of exposed hamsters humanely—euthanasia recommended. :contentReference[oaicite:22]{index=22}
