Wuchereria bancrofti: freeze-fracture study of the epicuticle of microfilariae.
The freeze-fracture technique was used to analyze the surface of microfilariae of Wuchereria bancrofti. The examination of thin sections showed that the epicuticle is formed by two closely apposed membrane-like structures, appearing as hepta-laminated structures. Freeze-fracture replicas revealed the presence of two fracture faces. The outer one is smooth but presents rosette-like structures. The inner face, which is in contact with the hypodermal cells, presents a large number of particles.
