Department of Parasitology and Institute of Endemic Diseases, College of Medicine, Seoul National University, Korea.

The morphological characters of the microfilaria of Brugia malayi collected in Cheju-Do, Korea were described and compared with those or other local strains, already reported from the Malay Archipelago(Brug, 1927), Huchow, South China (Feng, 1933), Hachijo Kojima, Japan (Hayashi, 1951) etc. And it was found that there are no marked difference among these kinds of Microfilaria malayi.

The percentage measurements of the fixed points in the Microfilaria malayi from Korea are summarized as follows;

B.N.C.: 3.38%(2.90-3.72%), N.R.: 22.64% (17.36-25.81%), E.P.: 32.26% (27.49-36.60%), E.C.: 38.78% (34.90-41.72%), Inn. K. begin: 53.95% (49.50-58.84%) end: 67.87%(63.02-72.97%), G-1: 70.42% (60.22-75.23%), G-2:76.70% (75.10-78.32%), G-3:78.84% (77.81-79.59%), G-4:80.84%(79.82-81.35%), A.P.:82.94%(77.32-89.72%), Length: 193.39(±12.3 µ)(170.77-233.08 µ), Width: 7.04±0.37 µ(5.99-7.99 µ), Sheath: 268.48±17.07 µ(218.72-286.47 µ), Ratio(Cephalic space): 1: 0.78
