Ehrlichiosis ("Ehrlichia chaffeensis"), a bacterial infection transmitted by ticks, and its complications are examined here in a case-based learning approach. This case scenario describes a person who was bitten by a tick while farming and the complications they experienced. Students are presented with a patient case scenario that entails a detailed assessment of the patient's physical status, medical history, vital signs, laboratory values, and treatment methods so as to provide a complete picture of the pathophysiology of ehrlichiosis. This case scenario can be used to teach physiology or pathophysiology of infection and inflammation topics in clinical courses such as nursing, physician assistant, pharmacy, and other allied health programs.
