CONCLUSION
Overall, the prevalence of fungal detection was found to be significantly higher in the airways of MA horses than SA and/or CTL horses. Due to the high proportion of positive fungal detection, by either cytology or culture, in TW of CTL horses, investigations based on this type of samples were found to be uninformative in a clinical context. On the other hand, fungal detection by culture (but not by cytology) in BALF has been identified as a significant risk factor for mild-moderate asthma in horses.
