Precise volumetric quantification of tumor spheroids using a voxel counting approach, and label-free dead tissue detection in the spheroids based on intrinsic optical attenuation contrast, were demonstrated. Immunology and Infection Use of Image Cytometry for Quantification of Pathogenic Fungi in Association with Host Cells Charlotte Berkes1,2, Leo Li-Ying Chan2,3, Alisha Wilkinson1,2,3, Benjamin Paradis2,3 1Department of Biology, Merrimack College, 2Center for Biotechnology and Biomedical Sciences, Merrimack College, 3Department of Technology R&D, Nexcelom Bioscience LLC Here, we demonstrate how image cytometry can be used for quantification of pathogenic fungi in association with host cells in culture. This technique can be used as an alternative to CFU enumeration.
