A parasitic disease, also known as parasitosis, is an infectious disease caused by parasites. [1] Parasites are organisms which derive sustenance from its host while causing it harm. [ 2 ] The study of parasites and parasitic diseases is known as parasitology . [ 3 ]
Schistosomiasis, also known as snail fever, bilharzia, and Katayama fever, [1] [2] [9] is a disease caused by parasitic flatworms called schistosomes. [5] It affects the urinary tract or the intestines. [5] Symptoms include abdominal pain, diarrhea, bloody stool, or blood in the urine. [5]
While none of the main four species of malaria parasite that cause human infections are known to have animal reservoirs, [359] P. knowlesi is known to infect both humans and non-human primates. [52] Other non-human primate malarias (particularly P. cynomolgi and P. simium ) have also been found to have spilled over into humans. [ 360 ]
P. moriformis causes a disease called protothecosis. This disease mainly infects cattle and dogs. Cattle can be affected by prototheca enteritis and mastitis. [35] Protothecosis is commonly seen in dogs; it enters the body through the mouth or nose and causes infection in the intestines. Treatment with amphotericin B has been reported. [36]
A zoonosis (/ z oʊ ˈ ɒ n ə s ɪ s, ˌ z oʊ ə ˈ n oʊ s ɪ s / ⓘ; [1] plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite, or prion) that can jump from a non-human vertebrate to a human. When humans infect non-humans, it is called reverse ...
Antihelminthics for infections caused by parasitic worms. Infectious diseases remain a significant global health concern, causing approximately 9.2 million deaths in 2013 (17% of all deaths). [3] The branch of medicine that focuses on infections is referred to as infectious diseases. [4]
Plasmodium falciparum is a unicellular protozoan parasite of humans, and the deadliest species of Plasmodium that causes malaria in humans. [2] The parasite is transmitted through the bite of a female Anopheles mosquito and causes the disease's most dangerous form, falciparum malaria. P. falciparum is therefore regarded as the deadliest ...
The 1990–2013 Global Burden of Disease Study estimated 5,500 direct deaths from schistosomiasis, [77] while more than 200,000 people were estimated in 2013 to die annually from causes related to schistosomiasis. [78] Another 20 million have severe consequences from the disease. [79] It is the most deadly of the neglected tropical diseases. [80]
