Comparison of wild-type and lysogenic SS2-4 cell morphology.

Abstract

<p>(a) Wild-type SS2-4 in mid-log growth phase; (b) Lysogenic SS2-4 in mid-log growth phase; (c) Wild-type SS2-4 in the stationary growth phase; (d) Lysogenic SS2-4 in the stationary growth phase; (e) Wild-type SS2-4 in the declining growth phase; (f) Lysogenic SS2-4 in the declining growth phase. In all three phases, the lysogenic strain had a shorter chain than the wild-type strain.</p
