A Babesia infection is a protozoan infection that can cause babesiosis in humans and animals. These pathogens attack the red blood cells. The decay of the erythrocytes causes symptoms typical of babesiosis: fever, anaemia and jaundice. In acute cases, a coffee-brown to red urine often appears as a symptom of the disease.
This disease is known as ‘dog malaria’ in canines. It is rarely diagnosed in humans because of a generally unobtrusive course of the disease. In patients with immunodeficiencies, however, the course of the disease can be serious.
