Morphology of parasporal inclusions
The morphology of parasporal inclusions produced by true fecal isolates
can be divided into four different groups (Fig. 3).
[Fig. 3 here]
These include bipyramidal, spherical, irregularly shaped or irregularly
pointed. Of the 190 isolates tested, 125 (65.8%) formed bipyramidal
inclusions, and 63 (33.2%) were spherical. All H3abc isolates
demonstrated bipyramidal inclusions. The same was true for H8ab and H7
isolates (Table 1).
