There have been increased numbers of stillborn and undersized calves in the region this fall. There has been association between Theileria orientalis Ikeda and abortions in cattle, but the pathogenesis and frequency has not been researched. We are interested in obtaining samples from aborted/stillborn calves and their dams. Please contact your veterinarian to submit fresh/frozen spleen from the fetus, EDTA blood from the dam, and formalin fixed placenta when available. If we received these with a history and indication this is for our research study, we will test the samples free of charge. Please feel free to contact ViTALS with any questions.
