In this video we observe a red blood cell under darkfield microscopy.
At first, two bright inclusions can be seen inside the cell — unusual structures not found in healthy red cells.
As time passes, these inclusions begin to stretch, shift, and merge, forming a longer rod-like shape. The structure continues to transform, bending and elongating, before finally settling into a hollow, capsule-like form.
This dynamic activity is consistent with pleomorphic microbial behaviour — organisms capable of changing their shape and adapting inside red blood cells.
Such transformations highlight how living forms within the blood may influence health, oxygen delivery, and immune activity.
