Fungal isolation and identification in 21 cases of guttural pouch mycosis in horses (1998-2002).

Abstract: This aetiological study of guttural pouch mycosis (GPM) in the horse was based on the retrospective study of 21 horses brought into the National Veterinary School of Lyon (France) between 1998 and 2002. Biopsies were taken from the lesions caused by GPM during endoscopic examination. In 87% of the cases, direct examination gave positive results, whereas 43% of the cultures were found to be negative. The main fungi observed were Aspergillus fumigatus (in three cases), A. versicolor (in two cases, together with other fungi), and A. nidulans and A. niger (one case each). In six cases, the Aspergillus species could not be identified. In two cases, cleistothecia and/or Hulle cells were observed. In three cases, fungi other than Aspergillus were seen, mixed or not with Aspergillus. These results underline the importance of Aspergillus fumigatus in the development of GPM in horses.

This research studied the types of fungi that cause guttural pouch mycosis (GPM) in horses, finding that Aspergillus fumigatus is frequently involved.

Study Overview

  • This research took place at the National Veterinary School of Lyon in France from 1998 to 2002, involving 21 horses suffering from guttural pouch mycosis (GPM).
  • GPM is a fungus-based disease that affects the guttural pouch of horses. The researchers conducted a study to identify the types of fungi responsible for this condition.
  • The diagnosis of GPM was based on biopsy samples taken from the site of the lesions during an endoscopic examination.

Results and Findings

  • The results of this study were largely dependent on direct examinations and culture tests performed on the biopsied tissue samples.
  • Direct examination resulted in identifying fungi in 87% of the cases, while 43% of the cultures were found to be negative, which means no fungi were grown in these samples.
  • The main fungi identified through this study were various species of Aspergillus. Aspergillus fumigatus was observed in three cases, A. versicolor was found in two cases (alongside other fungi), and A. nidulans and A. niger were identified in one case each.
  • In six cases of the study, the species of Aspergillus could not be specifically identified.
  • In two instances, researchers found cleistothecia and/or Hulle cells, which are specific types of fungal structures.
  • In three cases, other types of fungi were present, either alone or along with Aspergillus.

Conclusions

  • The findings of this study underscore the significant role of Aspergillus fumigatus in the development of guttural pouch mycosis in horses.
  • This information could be useful in exploring more effective treatment strategies for GPM in horses, by targeting this particular fungus.
