title: Studies on the use of gerbil-derived Babesia divergens antigen for diagnosis of bovine babesiosis.
abstract: Babesia divergens antigen obtained from bovine and gerbil erythrocytes was compared for the diagnosis of bovine babesiosis by the indirect immunofluorescence antibody test (IFAT) and the enzyme-linked immunosorbent assay (ELISA). Using a range of sera from the field and from experimental cattle, it was found that antigen from the two sources did not differ significantly in sensitivity or specificity. Antigen from gerbils may, therefore, be used for serological surveys of bovine babesiosis caused by B. divergens. The IFAT and ELISA were also compared and it was concluded that they are equally effective in the detection of positive samples. For small-scale surveys, the IFAT using gerbil-derived antigen is adequate, but for large surveys the ELISA is preferable.
