What are the two hosts of Schistosoma?
The intermediate hosts of Schistosoma spp. are various species of freshwater snails. Eggs are shed from the human host in feces or urine. Under optimal conditions in the environment, the eggs hatch and release miracidia, which swim and penetrate specific snail intermediate hosts.
What is the host of blood fluke?
The life cycle of human schistosomes includes two obligatory hosts: the human host in which the adult male and female parasites sexually reproduce (dioecy) and a freshwater snail in which the parasite asexually multiplies.
How many hosts do Schistosoma species have?
The schistosomiasis life cycle has 2 hosts: snails and mammals. Asexual reproduction occurs in snails and sexual reproduction occurs in mammals. To control schistosomiasis, diagnosis has an important role.
What is the first and second intermediate host of Schistosoma spp?
Human Schistosomes
| Scientific Name | First Intermediate Host | Endemic Area |
|---|---|---|
| Schistosoma japonicum | Oncomelania spp. | China, East Asia, Philippines |
| Schistosoma malayensis | Robertsiella spp. | Southeast Asia |
| Schistosoma mansoni | Biomphalaria spp. | Africa, South America, Caribbean, Middle East |

What are the two major forms of schistosomiasis?
There are 2 major forms of schistosomiasis – intestinal and urogenital – caused by 5 main species of blood fluke.
What are the host of Schistosoma mansoni?
The life cycle of schistosomes includes two hosts: humans as definitive hosts, where the parasite undergoes sexual reproduction, and snails as intermediate hosts, where a series of asexual reproductive takes place.
What is the definitive host of Schistosoma Mekongi?
Schistosoma mekongi is a parasitic blood-fluke found exclusively in the Mekong river basin of Laos and Cambodia in South-east Asia. Humans are the definitive host for the parasite, which causes damage to the liver, spleen, gastrointestinal tract, and esophagus.
What is the molluscan host of Schistosoma in the Philippines?
The control of schistosomiasis japonica; observations on the habits, ecology and life cycle of Oncomelania quadrasi, the molluscan intermediate host of Schistosoma japonicum in the Philippine Islands.
What are the primary host and the intermediate host of a blood fluke?
Flukes (Trematodes) The primary host is a vertebrate, where the flukes reproduce sexually. The intermediate host is typically a snail, where asexual reproduction occurs. Flukes can be found in any place where untreated human waste is utilized as manure.
What is the scientific name of blood fluke?

What is Schistosoma (blood fluke)?
Genus: Schistosoma Schistosoma is commonly known as the blood fluke. It is a dioecious parasite commonly found in the human hepatic portal or pelvic veins. Some species are parasites in vein of birds and mammals.
How many types of Schistosoma are there?
There are five main species infecting humans: Schistosoma mansoni, S. haematobium, S. japonicum and two geographically localized species S. intercalatum and S. mekongi. Schistosoma requires the use of two hosts to complete its life cycle.
What is the causative agent of schistosomiasis?
