A20-A28: Certain zoonotic bacterial diseases

A24: Glanders and melioidosis

Glanders and melioidosis are infectious diseases caused by different types of bacteria. Glanders, primarily affecting horses and other equines, is caused by the bacterium Burkholderia mallei. Humans can get infected through direct contact with sick animals or by inhaling contaminated dust. Melioidosis, on the other hand, is caused by Burkholderia pseudomallei and is found in the soil and water of certain regions. Humans usually get infected from direct contact with contaminated soil or water. Both diseases present similar symptoms, which may include fever, muscle and joint pain, and skin abscesses. Glanders often affects the upper respiratory tract, and can cause nodules and ulcers in the nose. Melioidosis can affect almost any system in the body, sometimes leading to severe lung or blood infections. Both diseases progress rapidly if untreated, and can be fatal.
