Fungal Infections in Guinea Pigs

What is a fungal infection in guinea pigs?

A fungal infection in guinea pigs is caused by the skin fungi Trichophyton mentagrophytes and Microsporum, with Microsporum being the most common culprit. You can recognize a fungal infection by the appearance of bald, round patches, flaking skin, and sometimes crusts. The symptoms are mainly visible around the ears, eyes, and lips. Generally, the guinea pig is not very bothered by it, although in some cases it may cause mild itching.

How does a guinea pig get a fungal infection?

A guinea pig can become infected with fungi through direct or indirect contact. Indirect transmission can occur via hay, the cage, or the food and water bowls. Young guinea pigs are particularly susceptible.

How is the diagnosis made?

If the clinical signs suggest a fungal infection, we perform a microscopic examination. To be completely certain, we also carry out a fungal culture using skin and hair samples. The results of the fungal culture are usually available after about 10 days.

Is a fungal infection contagious?

Fungal infections are highly contagious between guinea pigs. They are also a zoonosis, which means they can be transmitted to humans. Good hygiene is therefore very important. If you develop symptoms yourself, contact your doctor.

How do you treat a fungal infection in a guinea pig?

Treatment of a fungal infection involves medication and a special shampoo. The treatment usually lasts 4 to 6 weeks, and sometimes a repeat course is necessary. It is also important to treat the guinea pig’s living environment.
