Schistosoma haematobium in the bladder, cross section of an adult couple (female lies curled up inside the male).
bilharzia. schistosoma haematobium in the urinary bladder. enlarged cross-section of an adult pair ("pair fluke"). the male rolls up the smaller female (Canalis gynaecophorus) from the outside. the sexual organs are cut in both. the numerous papillae are visible on the surface of the male. the males can reach a size of up to 20 mm, the females up to 15 mm.
bilharzia. egg of Schistosoma haematobium. typical for Schistosoma haematobium is the terminal spine. in contrast to other trematodes, the schistosomes do not have a lid (operculum). egg size: 50 x 150 µm.
Bilharzia. egg of Schistosoma intercalatum. in comparison to Schistosoma haematobium, Schistosoma intercalatum also has an end spine, but the egg is narrower and tapers towards the ends. egg size: 60 x 160 µm
bilharzia. eggs of Schistosoma intercalatum. clearly visible are the narrow body and the terminal spine. embryogenesis is not yet completely completed. Schistosoma intercalactum lives in the venous plexus of the intestine and the portal vein. about 200 eggs are produced per day. Schistosoma intercalatum is mainly found in central africa.
bilharzia. egg of Schistosoma japonicum. the egg is oval in comparison to other Schistosoma species, the sting is only rudimentary. the eggs are rather small and measure 55 x 90 µm. up to 3000 eggs are produced per day. Schistosoma japonicum lives in the venous plexus of the intestine and portal vein. the infection is widespread in China, Indonesia and the Philippines.
bilharzia. t.s. of a Schistosoma mansoni pair. the large male encloses the smaller female in the Canalis gynaecophorus. on the surface of the male the papillae are clearly visible. Schistosma mansoni live in the vein plexuses of the intestine and portal vein. the females produce about 300 eggs/day.
Bilharzia. view of a pair of Schistosoma mansoni. the larger male is shown brighter, the darker, narrower female lies close to the male inside. the tegument is thinner than in other worms, but the skin appears thicker and thicker due to the surface coat (important for blood survival).
bilharzia. egg from Schistosoma mansoni. clearly recognizable is the typical lateral spine. egg size: 50 x 150 µm. the egg is avital (recognizable by its brownish and no longer transparent colour).
Bilharzia. adult Schistosoma mansoni female. the small, brightly appearing female has a long yolk duct.
Bilharzia: egg from Schistosoma haematobium, the vital egg, recognizable by its transparency, has a terminal spine, compared to Schistosoma intercalatum the egg is clumsier.
Bilharzia. Schistosoma haematobium. Biopsy from the bladder. There's a distinct eosinophilic granuloma.
Bilharzia. appendix biopsy with Schistosoma japonicum. an eosinophilic granuloma begins to form. the eggs are visible as dark purple oval structures.
