Chroococcus turgidus with chytrid parasite
Chroococcus turgidus, attacked by Chytridiomycota cells. The arrows point to the three chytrid cells; the rhizoids they have drilled through the protective jelly to the host cell are clearly visible in the top two. The cell mass of the cyanobacteria is visibly reduced. In the image attached below, a sucked out Chroococcus cell. Scale bar indicates 10 µm.
