The microfilaria of Brugia timori (Partono et al. 1977 = Timor microfilaria, David and Edeson, 1964): morphologic description with comparison to Brugia malayi of Indonesia.
The microfilaria of Brugia timori was compared with microfilariae of Indonesian strains of periodic and subperiodic Brugia malayi using alcohol-fixed (stained) and formalin-fixed (unstained) preparations. As noted by other observers of the Timor microfilaria, the absence of a stained sheath in Giemsa preparations, a long cephalic space with a length-to-width ratio of about 3:1, and a great overall body length are features which most readily distinguish this parasite. Additionally, B. timori has greater numbers of single row nuclei in the terminal column of body cells and a lesser bulge of the cuticle surrounding nuclei in the distal portion of the tail than does B. malayi. About 60% of B. timori microfilariae were exsheathed in haemalum-stained thick blood films. Brugia timori microfilariae were found to be distinct from microfilariae of B. malayi by comparing percentages of total body length included between the cephalic tip and major internal anatomic markers.
