Schistosomiasis, also known as snail fever, bilharzia, and Katayama fever, [1] [2] [9] is a disease caused by parasitic flatworms called schistosomes. [5] The urinary tract or the intestines may be infected. [5] Symptoms include abdominal pain, diarrhea, bloody stool, or blood in the urine. [5]
Swimmer's itch was known to exist as early as the 19th century, but it was not until 1928 that a biologist found that the dermatitis was caused by the larval stage of a group of flatworm parasites in the family Schistosomatidae. [7] The genera most commonly associated with swimmer's itch in humans are Trichobilharzia [4] and Gigantobilharzia.
S. haematobium causes urinary schistosomiasis, so eggs will be shed in the urine; S. mansoni and S. intercalatum reside in the mesenteric venous plexus, so eggs will be shed in the feces. [5] Looking at the stool specimen under a microscope, the species can be distinguished; S. intercalatum eggs have a terminal spine (as seen in the figure ...
By MARIA CHENG LONDON (AP) -- In a skeleton more than 6,200 years old, scientists have found the earliest known evidence of infection with a parasitic worm that now afflicts more than 200 million ...
Only one species is known to infect crocodiles - Griphobilharzia amoena. This species infects the freshwater crocodile Crocodylus johnstoni . Phylogenetic analysis shows that the genus Griphobilharzia rather than being a basal schistosome is a relation of the spirorchiids that infect freshwater turtles. [ 2 ]
The infection is known by an eponymous term bilharzia or bilharziasis, as well as by schistosomiasis. Bilharz was born and educated in Sigmaringen , Hohenzollern-Sigmaringen , Germany. After graduating in natural science and philosophy from the Albert-Ludwigs-Universität in 1845, he earned a medical degree from the University of Tübingen in 1849.
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 the leading cause of bladder cancer (only next to tobacco smoking). [2] [3] The diseases are caused by the eggs.
Natalie Clark, the girlfriend of popular YouTuber Billy LeBlanc, died after contracting a bacterial illness from eating raw oysters. LeBlanc also developed the infection and was severely ill.
