Association between fungal detection and extrinsic
factors
The likelihood of finding fungal elements in TW and BALF by culture and
cytology was not significantly associated with either housing (pasture,
straw or shavings) or feeding (dry, wet or sterilized hay). No
significant associations were found between fungal detection in TW or
BALF by culture or cytology and identification of bacteria in TW,
identification of Mycoplasma spp in TW or identification of virus
in TW.
Horses where EHV-2 was detected in BALF had 2-fold higher odds of
exhibiting a positive fungal culture in BALF (Table 3).
