Detection of Neospora caninum antibodies in Commercial Fetal bovine serum (FBS) by ELISA

Neospora caninum is a worldwide distributed pathogen which causes abortions in dairy cattle, leading to economic losses in the cattle industry. In this study ten different available lots of commercial fetal bovine serum samples and sixteen different lots of prototype fetal bovine serum were tested using a commercially available ELISA kit for the presence of total antibody to N. caninum. 100% (10/10) of the commercial FBS and 37.5% (6/ 16) of the prototype fetal bovine serum examined in this study were positive for N. caninum. This finding showed the high frequency of
N. caninum infection in used commercial fetal bovine serums.
