The most important of these is Schistosoma intercalatum, and server hundred cases of human infection with this worn have been recorded from Zaire. Also in this edition, two additional species of trematodes, Schistosoma mekongi and Schistosoma intercalatum, were described in the table of differential morphology of helminth eggs. [these species cause schistosomiasis/bilharzia in humans and ruminants] Parasite morphology: Blood flukes form five different developmental stages: eggs, miracidia, sporocysts, cercariae and adult worms. MORPHOLOGY AND LIFE CYCLE OF SCHISTOSOMA SINENSIUM PAO, 1959, FROM NORTHWEST THAILAND George J. Greer*, Viroj Kitikoont, and Chantima Lohachitt Division of Parasitology, Institute for Medical Research, Kuala Lumpur, Malaysia ABSTRACT: Schistosoma sinensium Pao, 1959, was first isolated from an unidentified snail in Szechuan Province, Symptoms of schistosomiasis result primarily from penetration of cercariae (cercarial dermatitis), from initiation of egg laying (acute schistosomiasis or Katayama fever) and as a late stage complication of tissue proliferation and repair (chronic schistosomiasis) They differ from each other only minute detail. The female, which is longer and more slender than the male (up to 10 to 14 mm in length), is held within the groove of the male. Differences in egg morphology can be used to … Drawings of these eggs, however, were not included in the figures. Morphology of the organism Life cycle, hosts and vectors Disease, symptoms, pathogenesis and site Diagnosis Treatment, prevention and control: The most significant trematodes from a clinical point of view are blood flukes, Schistosoma mansoni, S. japonicum and S. hematobium. Keywords: Schistosoma mansoni, schistosomiasis, Praziquantel, resistance, morphology, eggs, tegument Introduction Schistosomiasis is a disease caused by blood fluke trematode, Schistosoma spp., where Schistosoma haematobium, Schistosoma japonicum , and Schistosoma mansoni are the three main species affecting humans (Utzinger and Keiser, 2004 ; Gryseels et al., … A description of a Uganda strain of Schistosoma rodhaini Brumpt, 1931, is presented and the data are compared with published data on strains from other Central African localities. Schistosoma mansoni is dioecious and sexually dimorphic. The bodies of the cercariae, by means of the Iytic ferments of their penetration glands and their capacity for active movement, pass through the tissues and eventually reach the venous circulation…
The tegument of males have tubercles on the dorsal surface, whereas the tegument of … On the Morphology of Schistosoma rodhaini from Kenya* - Volume 40 Issue 1-2 - M. F. A.

The adult worms are morphologically indistinguishable from those of Schistosoma haematobium, but they parasitize the intestinal venous plexuses of man, not the vesical plexuses, and they cause intestinal schistosomiasis without bladder involvement. On the morphology of Schistosoma rodhaini (Trematoda, Digenea, Schistosomatidae) - Fripp - 1967 - Journal of Zoology - … The cercariae of the three species of Schistosoma dealt with here can all survive for about two days, and penetrate unbroken skin.
