Armadillo skin mycoses

What is it?

Armadillo skin mycoses brings together several skin infections caused by microscopic fungi. In this animal with a bony shell (called dermal shell), fungi mainly affect areas of unprotected supple skin, between the plates, on the stomach, limbs and head. These diseases are little documented in armadillos in breeding or captivity, but they are known in other burrowing mammals living in close contact with soil and humidity, a lifestyle similar to that of the armadillo. Certain responsible fungi can also infect humans, which justifies particular vigilance when handling these animals.

Commonly observed signs

These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.

Causes and risk factors

Skin mycoses are caused by filamentous or yeast-like fungi which colonize the superficial layer of the skin. In burrowing mammals like the armadillo, soil fungi (known as geophilic fungi) are particularly responsible, because the animal digs and lives in permanent contact with damp earth. Other opportunistic fungi can also develop on skin already weakened by injury, stress or underlying disease.

A humid, poorly ventilated or insufficiently cleaned environment encourages fungal proliferation.

Prolonged contact with contaminated soil, both in captivity and in the wild, increases the risk.

A weakened immune system, for example as a result of another illness, the stress of captivity or an unsuitable diet, makes the animal more vulnerable.

The presence of wounds or skin irritations makes it easier for fungi to enter.

Promiscuity with other carrier animals may also play a role.

Diagnosis and care

Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.

Treatment

Treatment is generally based on antifungals applied locally in the form of solutions or shampoos, sometimes combined with systemic antifungal treatment in extensive or recurrent cases. Regular cleaning of lesions and disinfection of the environment accompany medical treatment.

Prevention

Possible complications

If left untreated, the lesions can spread and become superinfected with bacteria.

Significant skin damage can weaken the animal and impact its general condition.

In an immunocompromised animal, the infection may become difficult to completely eliminate.

When to see a veterinarian

Transmission to humans

Certain fungi responsible for skin mycoses in burrowing animals can be transmitted to humans by direct contact with infected skin or with a contaminated environment. It is recommended to wear gloves when handling a suspected animal and to wash your hands thoroughly afterwards.

Prognosis

The prognosis is generally favorable when the disease is treated early and the environment is cleaned up. Neglected cases or complicated by superinfection may require longer treatment and prolonged veterinary monitoring.
