Fig. 5From: 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 parasitemia in calves challenged with a low dose of the Tf-137-4 or Mo7 strain. The red and pink dots depicting positive parasitemia days of calves C1292 and C1290 (infected with the Tf-137-4 strain of B. bovis), respectively and green and blue dots the positive parasitemia days of calves C1291 and C1287 (infected with Mo9), respectively. Parasitemia was monitored by nested PCR on a daily basis for the first twenty DPI and on a biweekly basis thereafter until 11Â months post-infection.
