Pleurochrysis carterae CCMP645 cells in mid-exponential growth phase were transferred (10% v/v) into flasks containing either F/2 (Guillard, 1975) or L1 (Guillard and Hargraves, 1993) media, in duplicate. Host abundance in each flask was monitored by flow cytometry (FCM) on a BD FACScan(TM) System for a 106-day period. The frequency of sampling varied throughout the period of the study as indicated in the excel data file. At each sampling time point 1 ml volume sample was collected from each flask and preserved in 0.5% paraformaldehyde, then snap frozen in liquid nitrogen and stored at -80C until ready for FCM analysis. Flow cytometry sample acquisition time was one minute for all samples. FCM analysis was carried out as described in Marie et al. 2005.
