Cell-to-cell spread of C. neoformans leads to infection of previously uninfected cell. Following phagocytosis, human peripheral blood monocytes closely apposed to each other underwent fusion leading to cell to cell spread of C. neoformans. The small arrow points to the uninfected monocyte approaching the infected monocyte to sequester the yeast cells while the large arrow indicates the C. neoformans cells that have been fully transferred to the previously uninfected human monocyte.
