ABSTRACT
Serum and urine samples from cattle with experimental and spontaneous systemic mycotic infections were tested for the presence of galactomannan and the 18 kDa antigen from Aspergillus fumigatus by an inhibition ELISA and immunoblotting, respectively. High levels of galactomannan (approximately 80 ng/ml.) were detected in serum from two of three calves experimentally infected with A. fumigatus. In two out of three cows with spontaneous acquired aspergillosis a similar amount of galactomannan was detected. Galactomannan was not found in serum samples of 20 cows which aborted due to either experimental or spontaneous placental aspergillosis. Twenty-four of forty urine samples from normal cattle reacted positively in the ELISA, consequently, the assay was not applicable on bovine urine. The 18 kDa antigen from A. fumigatus was detected in the urine from one calf out of three calves experimentally infected with aspergillosis and in the urine from one cow with spontaneous aspergillosis. It is concluded that detection of galactomannan in serum and the 18 kDa antigen in urine may be used as an aid for the diagnosis of disseminated bovine aspergillosis with the exception of placental and probably gastrointestinal localization.
