CDB magnetotactic alignment in biofilm in human blood sample.

This is a known biosignature of CDB and magnetotactic bacteria.

After aligning. The CDB go through a cell-cell adhesion by producing extracellular polymeric substances to form the fibers

Magnetotactic bacteria: These bacteria synthesize magnetite (Fe₃O₄) or greigite (Fe₃S₄) crystals within membrane-bound vesicles called magnetosomes. These crystals align in chains, creating a magnetic compass that helps the bacteria navigate along Earth’s magnetic field lines. The process is tightly regulated and results in highly ordered, geometric crystal structures
