Fungal Infection (Ringworm) in Ferrets


Ringworms is a typical fungal disease which affects ferrets, regardless of age and gender; however, it is more common in young and infant ferrets. Ringworm infection in ferrets is due to two types of fungi: Micwspomm canis and Trichophyton mentagmphytes.

Other fungal diseases like fungal pneumonia (blastomycosis) or fungal infections of the central nervous system (cryptococcal meningitis), are uncommon in ferrets, but can occur when its immunity is low.

Symptoms and Types

Common symptoms for ringworms include hair loss, itching, and a moist, circular patch located where the ferret has the skin infection.


Ferrets usually contract ringworm through direct contact with an infected animal or object (e.g., bedding, grooming brush, or cage). Infection is especially spread when ferrets are overcrowded within an enclosure.

Ringworm infection is contagious to humans. Therefore, follow preventative measures and consult a veterinarian when you suspect your ferret is infected.


Ringworm infection is treated with anti-fungal medicines and topical ointments.


To protect yourself from ringworm infection, wash your hands thoroughly after touching an animal (or infected object) and wear gloves while handling them.
