Effect of Leptospira infection on actin filaments in endothelial cells detected by immunofluorescence microscopy.

Actin filaments in HMEC-1 and HDLEC are shown in green. The nuclei are stained in blue for all panels. Scale bars represent 50 μm. Quantified signal intensity of the host protein is indicated in the right-hand graph (mean +/- SD, p-value is indicated below the graph, the independent p-value shown as an asterisk for Copenhageni is compared to uninfected and Patoc-infected cells).
