Binomials names for some strains (CCAP 2502/1 to 2502/6) were from the culture collection website (https://www.ccap.ac.uk) as they were not given in the original paper (Geisen et al. 2015). The subject of the present study is highlighted in bold. B.

Fig. 3. Cooperative cyst formation. Trophozoites were placed on an agar plate with a monolayer of E. coli. Encystment took place when the plate became dry and the food source locally exhausted. Trophozoites aggregated around the first to encyst, forming a slightly raised mound of cysts. Left panel – This image is the first frame of a video (see supplementary data) taken to follow cyst aggregate formation. Right panel – This is the last image of the same video where black arrowheads point to cysts that have been produced during the time that the video was shot.
