Airborne endotoxin concentrations and the number of viable airborne gr
am-negative bacteria were measured in cow and calf stables. The total
amount of airborne endotoxin varied between 36 and 761 EU m(-3) (EU en
dotoxin units) in tile cow stables, and between 44 and 262 EU m(-3) in
the calf stables. No correlation was found between concentrations of
airborne endotoxin and the number of viable airborne gram-negative bac
teria. (C) 1998 Elsevier Science Ltd. All rights reserved.
