Abstract

Samples of Bacillus thuringensis Berl. were Isolated from field soil from Baghdad, Sulaimaneya, Deyala,
Anbar, Babylon, Maisan and Thi-Qar governorates. The Identification was based on the shape of protein crystal (crystal
body) using a 1500 and 2500 X microscope. Three morphological characters of the crystal body were recognized,
namely (pure rhombic bi-pyramidal, cubic bi-pyramidal and spherical).
