The above images are from a peripheral blood film was obtained from a patient living in Minnesota. Besides being an outdoorsman, he had traveled extensively in the past year and visited many parts of Africa and Asia. He had returned from the Sub-Saharan two weeks prior and had since spent time in his garden and walking in the nearby woods with his dog. The patient recalled seeing several ticks on his body, but he did not remember any tick bites.
