Fig. 7From: A novel modified-indirect ELISA based on spherical body protein 4 for detecting antibody during acute and long-term infections with diverse Babesia bovis strainsLong-term monitoring of B. bovis antibody responses by IFA in calves challenged with a low dose of the Mo7 (a. C1287, c. C1291) or Tf-137-4 (b. C1290, d. C1292) strain. A positive IFA result was defined as fluorescence ≥ 1+. Abbreviation: DPI, days post-infectionBack to article page
