We are studying the relationship between fish health and their ability to respond effectively to pathogens including the oomycete (water mold), Saprolegnia. The wild-caught fathead minnow from Pike Lake SK pictured below is infected with an oomycete, which has produced the filaments (hyphae) extending from it. The living Saprolgnia ferax hypha is stained with three fluorescent endomembrane probes. The growth rate of the hypha in the movie was 6.6 µm/min over 548 sec.
