Schistosomiasis, caused by one genus of trematodes, is the second most devastating of all human diseases caused by parasites, surpassed only by malaria. Neurocysticercosis, which arises when larvae of the pork tapeworm Taenia solium penetrate the central nervous system, is the major cause of acquired epilepsy worldwide.
Platyhelminthes are flatworms, divided into the cestode (tapeworms) class and the trematode (flukes) class. The life cycle of a worm can be very complex, with multiple hosts for different stages of the worm. Helminths are multicellular, and one might wonder why they are covered in microbiology.

An example of a Pseudocoelomate is the roundworm. Pseudocoelomate animals are also referred to as Blastocoelomate. Acoelomate animals, like flatworms, have no body cavity at all. Semi-solid mesodermal tissues between the gut and body wall hold their organs in place.

The free-living species of flatworms are predators or scavengers. Parasitic forms feed on the tissues of their hosts.
Figure 1 presents the results for the schistosomes, and differences between these and other parasitic flatworms are given below. All genes are transcribed from the same strand. The gene complement is typical of metazoans , but the gene order is unique. Twenty-two tRNA genes, 2 rRNA genes and 12 protein-coding genes were identified.
