Population structure of ribosomal IGS sequences from <i>N. bombycis</i>, <i>N.granulosis</i> and <i>V. cheracis</i> isolates.

<p>Comparisons were made using Wright’s index of fixation (<i>F_ST</i>) and net nucleotide substitutions per isolate (<i>D_a</i>). Levels of significance: *0.05, **0.01, ***0.001. Isolates are labelled as follows: A = <i>V. cheracis</i> (Australia), E = <i>N. bombycis</i> (England), U = <i>N. bombycis</i> (USA), C = <i>N. bombycis</i> (China), W = <i>N. granulosis</i> (Wales), Sc = <i>N. granulosis</i> (Scotland), Sw = <i>N. granulosis</i> (Sweden).
