Plain-English summary

Two horses were diagnosed with a serious condition called guttural pouch mycosis, which involves a fungal infection in a part of their throat. Both horses showed signs of severe nosebleeds, trouble swallowing, and pain in their jaw area, along with a runny nose that contained food. One horse improved gradually with medical treatment, while the other sadly had to be euthanized for further examination. The tests done on the second horse did not find the original cause of the problem, but they did identify a fungus that looked like Aspergillus, which is known to cause infections. Overall, one horse recovered while the other did not survive.

Abstract

The history and clinical findings of 1 horses with guttural pouch mycosis referred to us are described. The salient features of the history and clinical signs common to both cases were profuse spontaneous nasal haemorrhage, partial pharyngeal paralysis; subsequently bilateral nasal discharge containing food material, inability to drink and parotid pain became evident. One case made a gradual recovery with conservative medical treatment while the second case was destroyed and submitted for post-mortem, histopathological and microbiological examination. This examination failed to establish the initiating cause of the lesion but later stages were clearly associated with an invasive septate fungus morphologically resembling Aspergillus.
