Reviewed/Revised Jun 2018 | Modified Oct 2022

Glanders is a contagious, short or longterm, usually fatal disease of horses caused by the bacterium Burkholderia mallei. The disease is characterized by the development of a series of ulcerating nodules. The nodules are most commonly found in the upper respiratory tract, lungs, and skin. People, dogs, cats, and other species are susceptible, but infections in dogs are uncommon. Infections in people are often fatal.

Prevention and control depend on early detection and elimination of affected animals. Complete quarantine and rigorous disinfection is required for all housing and objects that have been in contact with the infected animal. Euthanasia is usually recommended for infected animals.
