Schistosoma haematobium ova - have a characteristic oval body with a long thin tail and are 50 microns in length. Although schistosomiasis is not found in the United States, 200 million people are infected worldwide. Many (perhaps half) of the eggs produced by Schistosoma mansoni and Schistosoma japonicum fail to penetrate the intestinal wall to be excreted and are instead carried via the portal circulation into the liver. Among 132 mice used, 30 of them were infected with 80–100 S. japonicum cercariae for collection of juvenile and adult schistosomes applied in in vitro tests. Kingdom Animalia Different Phylum, Classification, Characteristics Overview.
