Schistosoma spindale is a species of digenetic trematode in the family Schistosomatidae. It causes intestinal schistosomiasis in the ruminants. The distribution of Schistosoma spindale includes Sri Lanka, India, Bangladesh, Thailand, [1] Malaysia, and Laos. [2] The tegument of Schistosoma spindale under scanning electron microscope was studied ...
The life cycle stages: [43] The excretion of schistosome eggs in urine or feces depending on the species; The hatching of the eggs leads to the release of the free-swimming, ciliated larvae called miracidia; Miracidia find and penetrate the snails, which are the intermediate hosts (specific species of snails are dependent on the species of ...
An outline of the evolution of the schistosoma is now possible. The ancestral species infected freshwater turtles and the life cycle included gastropod hosts. Some of these species in their turn infected the marine turtles. [3] At some point members of species infecting marine turtles developed the ability to infect birds – most likely waterfowl.
The life cycle of a typical trematode begins with an egg. Some trematode eggs hatch directly in the environment (water), while others are eaten and hatched within a host, typically a mollusc. The hatchling is called a miracidium, a free-swimming, ciliated larva. Miracidia will then grow and develop within the intermediate host into a sac-like ...
Schistosoma is a genus of trematodes, commonly known as blood flukes.They are parasitic flatworms responsible for a highly significant group of infections in humans termed schistosomiasis, which is considered by the World Health Organization to be the second-most socioeconomically devastating parasitic disease (after malaria), infecting millions worldwide.
Schistosoma japonicum is an important parasite and one of the major infectious agents of schistosomiasis.This parasite has a very wide host range, infecting at least 31 species of wild mammals, including nine carnivores, 16 rodents, one primate (human), two insectivores and three artiodactyls and therefore it can be considered a true zoonosis.

Schistosoma intercalatum's life cycle is very similar to that of S. haematobium, except for some key differences. To start the life cycle, the human host releases eggs with its feces. In water, the eggs hatch to become miracidia, which penetrate the freshwater snail intermediate host. [5]
