摘要：Babesia microti causes “emergency” human babesiosis. However, little is known about the alterations in B. microti invaded red blood cells ( Bm -RBCs) at the individual cell level. Through quantitative phase imaging techniques based on laser interferometry, we present the simultaneous measurements of structural, chemical, and mechanical modifications in individual mouse Bm -RBCs. 3-D refractive index maps of individual RBCs and in situ parasite vacuoles are imaged, from which total contents and concentration of dry mass are also precisely quantified. In addition, we examine the dynamic membrane fluctuation of Bm -RBCs, which provide information on cell membrane deformability.
