Schistosomiasis japonica is a serious debilitating and sometimes fatal disease. It is the cause of schistosomiasis japonica, a disease that still remains a significant health problem especially in lake and marshland regions. Schistosomiasis is an infection caused mainly by three schistosome species; Schistosoma mansoni, Schistosoma japonicum and Schistosoma haematobium. Schistosomiasis is a disease caused by blood flukes of the genus Schistosoma. One may also ask, which life stage of Schistosoma japonicum is responsible for causing infection? Schistosoma japonicum Schistosomiasis is a parasitic disease caused by Schistosoma organisms that can cause acute and chronic infection. In CNS disease, this fluke locates in the brain, whereas Schistosoma mansoni and Schistosoma haematobium are more commonly found in the spinal cord. Schistosoma japonicum Some important foci exist in South America, the Middle East, Southeast Asia and in China. Diagnosis Introduction. It is of critical importance to find and treat people and to identify animals with low-level infections if the National Control Programme for China is to achieve schistosomiasis elimination. Seven schistosome species can cause infection in humans. With Schistosoma haematobium, this is the urinary system as well as the sacral and pelvic vessels, whereas with intestinal schistosomiasis (S. mansoni, S. japonicum, S. intercalatum, and S. mekongi) parasitization occurs in the intestinal mucosa. Diagnosis schistosomiasis perlu dicurigai pada pasien dengan gejala abdominal dan urogenital, disertai riwayat berkunjung ke daerah endemis. The eggs tend to be passed intermittently and in small amounts and may not be detected, so it may be necessary to perform a blood (serologic) test. Parasites A-Z Index These symptoms, also known as acute schistosomiasis (Katayama’s syndrome) may occur weeks after the initial infection, especially by Schistosoma mansoni and Schistosoma japonicum.

The S.japonicum RPA assay was developed to target highly repetitive retrotransposon SjR2 gene of … Adult Schistosoma worms live and copulate within venules of the mesentery (typically S. mekongi, S. intercalatum, S. japonicum and S. mansoni) or bladder (typically S. haematobium).Some eggs penetrate the intestinal or bladder mucosa and are passed in stool or urine; other eggs remain within the host organ or are transported through the portal system to the liver and occasionally … Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. Author Summary With the advantages of higher sensitivity and simpler ease of use over stool examination, antibody-detection methods have been integrated into programs for schistosomiasis control in the People's Republic of China after the notable decrease of prevalence and intensity of Schistosoma japonicum infection. And the results suggest that RPA-based assays can be used as a promising point-of-care test for the diagnosis of schistosomiasis. Lifecycle stages of a typical trematode, Schistosoma japonicum - by JRockley[Public domain], via Wikimedia Commons Commonly known as flukes, members of class Trematoda are all parasitic in nature. Schistosoma species (class Trematoda) are flukes, characterized by their flat, leaf-like morphology as adults, and use of gastropod mollusks (eg, snails) as an intermediate host.

FINAL DIAGNOSIS. ing out with the feces, can be used for clinical diagnosis. It differs form S. mansoni and S. haematobium in that it is a zoonosis in which a large number of mammals serve as reservoir hosts; cats, dogs and cattle playing major roles in the transmission of the disease. DISCUSSION. The choice of sample to diagnose schistosomiasis depends on the species of parasite likely causing the infection. Schistosomiasis is a disease mainly caused by schistosome eggs lodging and damaging the organs and tissues of the human host. Serology can be performed with variable sensitivity ranging from 41% to 78%. Microbiol Curr Res. Clinical Information.
