Nosema bombycis

Nosema bombycis^[1] is a species of Microsporidia of the genus Nosema infecting silkworms, responsible for pébrine. This species was the first microsporidium described, when pebrine decimated silkworms in farms in the mid-19th century. This description was made by Carl Nägeli. Louis Pasteur, taking up an idea of Osimo which had not been successful,^[2] showed breeders a practical way to select uninfected individuals to recreate new healthy farms.
