Pébrine
DISEASE OF SILKWORMS
Pebrine
Pébrine, or "pepper disease," is a disease of silkworms, which is caused by protozoan microsporidian parasites, mainly Nosema bombycis and, to a lesser extent, Vairimorpha, Pleistophora and Thelohania species. The parasites infect eggs and are therefore transmitted to the next generation.
