Pear-shaped appearance of Babesia

Babesiosis is a rare disease caused by single-celled parasites which infect red blood cells. Babesia mainly infect animals with humans only being occasionally infected. These parasites are transmitted to humans primarily by tick bites. Their name originates from Victor Babeș (1854-1926), a Romanian physician who first described them.
Some infected people are asymptomatic. Certain groups of people are vulnerable to severe infection like those without a spleen and those with an impaired immune system. Under the microscope, these parasites are oval shaped within the red blood cells, a pear-shaped appearance.
