Abstract
Antigens prepared from ovine granulocytes and tick cells infected with ovine strains of Anaplasma phagocytophilum, the causative agent of tick-borne fever, were tested in respect of their suitability for the assay of antibodies in ovine sera by enzyme-linked immunosorbent assay (ELISA) and by indirect immunofluorescent antibody test (IFAT). Antigens prepared from tick cells were as sensitive and specific as those expressed in ovine granulocytes for the detection of specific antibodies by ELISA, but they failed to react in the IFAT with immune sera obtained from sheep previously infected with ovine strains of A. phagocytophilum.
