In '''horses''', the pathogenesis of [[Guttural Pouch Mycosis|'''guttural pouch mycosis''']] is largely unknown but is thought to relate to damage to the mucosal layer of the pouches by trauma or infection. This enables opportunistic ''Aspergillus'' fungi to invade and colonise the damaged tissue. | In '''horses''', the pathogenesis of [[Guttural Pouch Mycosis|'''guttural pouch mycosis''']] is largely unknown but is thought to relate to damage to the mucosal layer of the pouches by trauma or infection.
