Histopathology of the gut of the silkworm, Bombyx mori Linn. infected with microsporidia
Keywords:

Abstract
Ultrastructure of gut of the silkworm, Bombyx mori infected with microsporidia exhibited cytoplasmic vacuolization in the form of large empty spaces, fewer mitochondria, different spore stages (meronts and spronts) as grayish black spheres and mature spores. The meronts and sporonts measured 0.61 and 0.56 nm and 1.23 and 0.89 nm in length and width respectively. The lightly infected gut, did not show any vacuolization but in the heavily infected gut cell, cytoplasm destruction resulted in the formation of empty spaces.
