A Brugia malayi microfilaria after losing its sheath in calcium chloride solution.

Brugia malayi microfilariae found in the bloodstream of the infected human host are surrounded by a translucent sheath derived from the embryonic egg shell. The sheath appears to protect the microfilariae from interaction with the immune system. Treatment with calcium chloride results in loss of the sheath. The image shows the luminescence of an exsheathed microfilariae under light microscopy. Schroeder et al.
