Etymology: In 1851 the German physician Theodor Bilharz, working at a hospital in Cairo, examined the body of a patient and found a small worm in the blood vessels around the bladder. He described it in 1852 as "Distoma haematobium," and the name stuck to the species. The second part, "haematobium," combines the Greek "haima," meaning blood, with a suffix that likely comes from the Greek "bios," meaning life, so the name roughly means "living in blood." The name refers to the worm's habitat, not to any bloody symptom, although the infection does cause blood in the urine. The worm was later moved to the genus "Schistosoma," a name coined in 1858 from Greek roots meaning "split body," a reference to the male's flattened body that cradles the female. Bilharz's name survives in the common disease name "bilharzia," used mainly in Africa and the Middle East for the infection this worm causes. Some ancient Egyptian medical texts describe blood in the urine, which may refer to the same disease, but the link is uncertain.
