It is found in Africa and the Middle East. It is the major agent of schistosomiasis, the most prevalent parasitic infection in humans. [1] It is the only blood fluke that infects the urinary tract, causing urinary schistosomiasis, and is a leading cause of bladder cancer (only next to tobacco smoking). [2] [3] The diseases are caused by the eggs.
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.
[21] [19] For human schistosomiasis, a similar type of dermatitis called "swimmer's itch" can also be caused by cercariae from animal trematodes that often infect birds. [16] [19] [23] Cercarial dermatitis is not contagious and can not be transmitted from person-to-person. [24] Symptoms may include: Flat, red rash [19] Small red, raised pimples ...
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.
In 2002, an 11-month-old baby boy is infected with Baylisascaris procyonis worms that cause him to sleep excessively, lose his balance and almost go blind. In 1967, an elderly Vietnam War veteran was diagnosed with malaria and successfully treated, but later in 2003, he has his legs and testicles destroyed by Lymphatic filariasis caused by Wuchereria bancrofti worms.
The nearly five-minute video consists entirely of close ups of the infestation and footage of the maggots being pulled from the ear. The video, posted earlier this year to YouTube, has more than ...
Schistosoma mansoni is a water-borne parasite of humans, and belongs to the group of blood flukes (Schistosoma). The adult lives in the blood vessels (mesenteric veins) near the human intestine. It causes intestinal schistosomiasis (similar to S. japonicum, S. mekongi, S. guineensis, and S. intercalatum). Clinical symptoms are caused by the eggs.
The soil-transmitted helminths (A. lumbricoides, T. trichiura, N. americanus, A. duodenale), schistosomes, and filarial worms collectively infect more than a quarter of the human population worldwide at any one time, far surpassing HIV and malaria together. [35] [37] Schistosomiasis is the second most prevalent parasitic disease of humans after ...
