<p>The microfilaria of Brugia pahangi obtained from anexperimentally infected dog were observed with the electron microscope.The sheath was composed of small granules and was coveredwith electron-dense particles on the outer surface and with smallgranules on the inner surface. The cuticle was composed of anoutermost layer, a trilaminate membrane and an inner layer. Thehypodermis was composed of four components as in the adult stage(two small ones on the lateral sides, two large ones on the dorsal andventral sides). The muscle cells comprised a single layer under thehypodermis on the dorsal and ventral sides. On each side, two musclecells usually appeared in a transverse section. The thick myofilamentwas surrounded with 8 to 12 thin myofilaments. Dense bodies werepresent around the cephalic space. In the cells of the nuclei column,the cytoplasm was very narrow, and the electron-dense nucleus closeto each other. The cuticular central canal was connected to the buccalcavity and to the inner body. A sponge-like structure was seen atthe junctional part of the canal and the inner body. The inner bodyshowed a homogeneous granular appearance. Eight cephalic papillaewere observed at the head tip. Two amphids, each having more thaneight cilium-like structures, were connected with the nerve elementsand open in the head part. Two phasmids, each having one ciliumlikestructure, opened in the caudal part. Two types of neurosecretorygranules were observed in the nerve ring and the dorsal and ventrallongitudinal nerves were clear except in the anterior and the posteriorpart of the worm. The excretory and the anal vesicles had contactswith thin and thick cytoplasmic processes respectively, and thesevesicles opened to the exterior. The nuclei of the G cell and R cellsshowed similar electron-density. Lamellate structures were presentin the muscle and the hypodermis.</p>
