Sixty worms collected from 3 infected persons were studied morphologically. The adult worms are leaf-shaped, 1519.4-2056.3 x 466.4-564.0 microns in size. The width of the collar is 235.8-297.3 microns. A row of 24 collar spines with size of 22.5-35.6 x 8.8-10.6 microns is arranged on the collar symmetrically with dorsal and ventral interruption. The oral sucker is terminal, 107.6-148.6 x 102.5-148.6 microns. The length of the prepharynx is 25.6-66.7 microns, the pharynx, 97.3-127.8 microns and the oesophagus 117.9-205.0 microns. The caeca 764.3-1,248.8 x 21.0-39.0 microns extends to the distal end of the body. The acetabulum is anterior to the middle level of the body, 205.0-240.9 x 205.0-235.8 microns in size. Two testes, situated in the posterior one third of the body, is slightly oval, in tandem; the anterior one is 133.3-199.9 x 199.9-256.4 microns in size, and the posterior one, 178.9-251.3 x 164.0-246.0 microns. The Cirrus pouch is kidney-shaped, 211.5-248.5 x 112.8-194.8 microns in size, located between the bifurcation of the intestine and the acetabulum, containing the seminal vesicle and cirrus. The ovary is oval in shape, 71.8-92.3 x 76.8-97.4 microns in size, situated in the middle of the body. The vitellaria are distributed on each side from the acetabulum to subterminal, consisting of many follicles. The uterus is short, convoluted between the anterior testis and the acetabulum, containing 0-6 eggs.(ABSTRACT TRUNCATED AT 250 WORDS) | lld:pubmed |
