Studies on the Microfilariae of Loa loa, Wuchereria bancrofti, Brugia malayi, Dirofilaria immitis, D, repens and D. aethiops

Abstract

(1) The microfilariae of L. loa, W. bancrofti, B. malayi, D. immitis, D. repens and D. aethiops have been studied in detail, using phasecontrast and ultra-violet microscopy and vital staining techniques.(2) In these microfilariae the cells of the “oten Mundgebilde” have been renamed “hook-muscle cells” as they appear to be concerned with the movements of the hook.(3) Two cells have been demonstrated in the nerve ring by means of ultra-violet photomicrography and vital staining with rongalit methylene blue.
