Abstract

We present the real time quantitative analysis of Vibrio vulnificus-infected host cells using high stability quantitative phase microscopy (HSQPM). It provides the ability to retrieve the phase or optical path length distribution over the cell from a single interferogram image, which has been measured with nanometer path length sensitivity for long periods of time. We have applied HSQPM to study dynamic cell morphologic changes and to quantify noninvasively cell volumes of rat basophilic leukemia RBL-2H3 cells infected with pathogenic bacteria V. vulnificus strains, wild type (MO6-24/O) and RTX toxin mutant (CMM770). During the process of V. vulnificus wild type infection to RBL-2H3 cells, the dynamic changes of quantitative phase images, cell volumes and areas were observed in real time using HSQPM. In contrast, the dramatic changes were not detected in RBL-2H3 cells infected with RTX toxin mutant. The results showed the good correlation between HSQPM analysis and biochemical assays such as lactate dehydrogenase (LDH) assay and β-hexosaminidase release assay. We suggest that HSQPM is useful real time quantitative method to study the dynamic process of host cells infected with pathogen in a noninvasive manner.
