FINE STRUCTURE AND LOCALIZATION OF ANIONIC SITES ON THE SURFACE OF MICROFILARIAE OF WUCHERERIA BANCROFTI.

Journal of Submicroscopic Cytology and Pathology, 21(1): 121-129, 1989.

SUMMARY

The fine structure of the sheath and the cuticle of microfilaria of Wuchereria bancrofti was analyzed and the results obtained were compared with those from other filarial parasites. Cationized ferritin particles bind to the surface of the sheath and the epicuticle. No binding of colloidal iron hydroxyde particles to the microfilaria surface was observed. Reaction product indicative of carbohydrates containing vic-glycol groups was not observed in thin sections of microfilaria submitted to the periodic acid-thiosemicarbazide-silver proteinate technique. The results obtained are discussed in relation to previous studies using lectins.
