Goats can contract pneumonia from pathogens such as Mannheimia hemolytica, Pasteurella multocida, and Mycoplasma spp. These bacteria can infect goats particularly when they face stress due to transportation, overcrowding, extreme weather conditions, or concurrent illnesses. Additionally, viral infections such as caprine infectious respiratory disease (CIRD) can weaken the goat’s immune system, making them more susceptible to secondary bacterial infections, which often lead to pneumonia.
