Capsular size of bacterial isolates.

Abstract

<p>Bacteria were visualized using electron microscopy and fluorescence microscopy with dextran exclusion. (A) Representative transmission electron microscopy images of SRL1 and TIGR4 following fixation using ruthenium red and lysine-acetate. (B) Capsular area of SRL1 and TIGR4 as visualized by electron microscopy. (C). Area of dextran exclusion per bacterial cell. (B-C) Line shows median. (Significant difference by Mann Whitney test, ** p < 0.01, ***, p < 0.001).</p
