Pathogen and Pathogenesis

Wet tail (proliferative ileitis) is caused by Lawsonia intracellularis, an obligate intracellular bacterium that infects intestinal epithelial cells causing hyperplasia and severe diarrhea. Stress is the primary trigger — weaning, transport, cage changes, and temperature fluctuations suppress immune function and allow latent infection to activate. Syrian hamsters aged 3-6 weeks are most susceptible.

Clinical Signs

Wet, matted perineum and tail (pathognomonic)
Severe watery diarrhea with characteristic odor
Lethargy, hunched posture, ruffled fur
Anorexia and rapid weight loss
Rectal prolapse in severe cases

Treatment Protocol

Immediate veterinary care is non-negotiable. Treatment involves: enrofloxacin or tetracycline antibiotics, subcutaneous fluids for dehydration, nutritional support via syringe feeding (Critical Care or Emeraid), and strict quarantine from other hamsters. Cage must be thoroughly disinfected — Lawsonia survives in feces for 2 weeks at room temperature.
