Abstract: Bovine reproductive disorders are of growing interest from both economic and health standpoints. The role that fungi play in these processes is becoming increasingly important. Study of the seroprevalence of anti-Aspergillus antibodies in cow sera taken from herds with previous reproductive disorders is therefore of great interest. We used an indirect ELISA technique, that had shown suitable results in previous studies in other animal species. Thirteen percent of the 387 animals tested in the current study were positive, accounting for 41% of herds. When this technique was applied to the sera of two fetuses, that were aborted due to aspergillosis, a significant difference in anti-Aspergillus antibody levels was found compared with those in control sera. The ELISA technique was compared with PLATELIA and PCR for 24 ELISA-positive cattle sera; these assays resulted in only one and three positive results, respectively. In conclusion, the ELISA analysis showed a significant seroprevalence of Aspergillus antibodies in herds with previous reproductive disorders. There is therefore a need for more attention to be paid to Aspergillus in the differential diagnoses of these conditions and to improve preventive methods to effectively control this organism.
