Amoeba mystery

Post by dy5 »

Does anyone know what's going on with this amoeba? There were several individuals of the same species in that particular sample, and all had the strange inclusions.

The amoeba is approximately 250µ long x 150µ wide. The largest circular inclusion is about 55µ in diameter and the 'dots' inside it are 2-3µ across.

Thanks, David

Hi David,

this amoeba is suffering a parasite attack from a Microsporidium-like parasite. Since the nucleus seems uneffected, the parasite most like is a Morellospora species. The unlucky amoeba beatifully contains all developmental stages of this parasite, from the amorphous intracytoplasmatic bodies to the compartments filled with lots of tiny spherical spores awaiting to be released from the dead amoeba to infect new victims.
