Pigeon fever, also known as dryland distemper, is a common bacterial infection that affects horses. It’s characterized by abscesses, most notably in the pectoral region (chest), hence the name “pigeon fever” due to the swelling resembling a pigeon’s breast. But How Does A Horse Get Pigeon Fever in the first place? Let’s delve into the causes, symptoms, and treatment options.
Understanding the Causes of Pigeon Fever in Horses
The bacterium Corynebacterium pseudotuberculosis is the culprit behind pigeon fever. This bacterium thrives in dry, dusty environments, which is why the infection is often called “dryland distemper.” So, how does this bacterium find its way into your horse?
The most common route of infection is through wounds, even minor abrasions or insect bites. Flies, especially stable flies and horn flies, can mechanically transmit the bacteria from an infected horse to a healthy one. Contaminated soil and bedding can also be sources of infection, particularly if the horse has any skin breaks. Interestingly, internal abscesses can also form, though less common, likely through inhalation or ingestion of the bacteria.
Another less common route of infection is through contaminated surgical instruments or injections. While rare, it’s crucial to maintain proper hygiene and sterilization procedures during any veterinary interventions.
Recognizing the Symptoms: Is It Pigeon Fever?
Identifying pigeon fever early on is key to effective treatment. The most obvious sign is the formation of external abscesses, most frequently in the chest muscles. These abscesses can be hot, painful, and filled with pus. However, abscesses can also develop in other areas, including the abdomen, legs, and even internally.

- Lameness (if abscesses are near joints)
- Swelling in the affected area
- Draining tracts from the abscesses
If you suspect your horse has pigeon fever, contact your veterinarian immediately for a proper diagnosis and treatment plan.

Pigeon Fever: A Closer Look at Common Scenarios
Imagine your horse has a small cut on its leg after brushing against a fence. This seemingly insignificant wound can become an entry point for the C. pseudotuberculosis bacteria, especially in a dusty paddock. Another common scenario is a horse developing an abscess after being bitten by flies carrying the bacteria.
