Megaklothovirus horridgei

Megaklothovirus horridgei is the largest virus ever discovered. It is 3.9 μm long, which is about twice the length of an Escherichia coli bacterium.[1] It was first discovered in 2018 on an Arrow Worm that it was infecting in the genus Spadella.[2] Before Megaklothovirus horridgei was understood to be a giant virus, it had been mistaken for bristles in 1967, and later for bacteria in 2003.[3][4]

Name

Megaklothovirus horridgei is named in tribute to Adrian Horridge,[5] the author of the 1967 article in which the viruses were mistaken for bristles.
