In 2009 the genomes of both S. mansoni and S. japonicum were published, with each describing 11,809 and 13,469 genes, respectively. S. mansoni genome has increased protease families and deficiencies in lipid anabolism; which are attributed to its parasitic adaptation. Proteases included the invadolysin (host penetration) and cathepsin (blood ...
All serum specimens are tested by FAST-ELISA using S. mansoni adult microsomal antigen. A positive reaction (greater than 9 units/μL serum) indicates infection with Schistosoma species. Sensitivity for S. mansoni infection is 99%, 95% for S. haematobium infection, and less than 50% for S. japonicum infection. The specificity of this assay for ...
Within the haematobium group S. bovis and S. curassoni appear to be closely related as do S. leiperi and S. mattheei. [citation needed] S. mansoni appears to have evolved in East Africa 0.43–0.30 million years ago. [citation needed] S. mansoni and S. rodhaini appear to have shared a common ancestor between 107.5 and 147.6 thousand years ago. [9]
Sparganosis is a parasitic infection caused by the plerocercoid larvae of the genus Spirometra including S. mansoni, S. ranarum, S. mansonoides and S. erinacei. [1] [2] It was first described by Patrick Manson in 1882, [3] and the first human case was reported by Charles Wardell Stiles from Florida in 1908. [4]
Biomphalaria glabrata is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.. Biomphalaria glabrata is an intermediate snail host for the trematode Schistosoma mansoni, which is one of the main schistosomes that infect humans. [2]

Male S. mansoni and S. haematobium will both take priority over S. intercalatum when it comes to mate selection, leading to a smaller proportion of female S. intercalatum available for mating. While crosses with S. mansoni give no viable offspring, the pairing with a male S. haematobium will result in a hybrid organism.
Schistosomiasis was first reported in the Mekong River's Lower Basin region in 1957, from Laotian island of Khong to Cambodian province of Kratié, specifically. [2] It was believed that the cause of these cases was Schistosoma japonicum until 1978, when Neotricula aperta was discovered and it was determined that the Schistosome was a unique species, Schistosoma mekongi.
