Chagas Disease, Adult Chagas disease is an infection caused by the protozoan parasite Trypanosoma cruzi. Another name for this infection is American trypanosomiasis. Chagas disease has two phases. In the initial (acute) phase of infection, you may or may not have symptoms. If the acute phase is not treated, the symptoms may go away, but the infection will not. If the infection has not gone away, it becomes a chronic infection. A chronic infection takes years to develop. Chagas disease can be
Abstract Trypanosoma brucei, the parasite, is not very common in the United States but is very common in Africa. Trypanosoma brucei is a disease that kills many people throughout Africa. Though we may not have it here it still affects people, in this paper we are going to look at the different ways T. brucei will infect people, the life cycle, the pathophysiology, the epidemiology, the signs and symptoms of the host, and last the different medicines that cure T. brucei. Trypanosoma brucei is a very
1. How does the kissing bug (e.g., Rhodnius sp., Triatoma dimidiate ) locate its human prey? The kissing bug ventures forth in search of the blood meal it takes squeezes from humans or sleeping pets. The bugs emerge while the inhabitants are sleeping “Due to these bugs tend to feed on people faces”. "Kissing bugs are also known as triatomine bugs”. These bugs defecate on the person later they bite and ingest blood. If Trypanosome cruzi parasites in the bug feces enter the body through mucous membranes
Human African Trypanosomiasis, commonly known as sleeping sickness is a highly prevalent parasitic disease in sub-Saharan Africa. The organism responsible for this infectious disease is the Trypanosoma brucei, which claims hold to humans and other animals, as its primary hosts. Since Trypanosoma brucei are parasitic, their environment is their host. The most common carrier is the African native tsetse fly, which is abundant in western and central regions of the continent (Kagbadouno et al. 2012)
I. A coma’s technical name is “Trypanosomiasis.” Many people think the person is asleep, but the person is actually in a deep state of unconsciousness. It happens worldwide, but mostly in Africa. There are about 50,000-70,000 cases a year. When a person is in a coma, they are unresponsive since they are unconscious. They also do not respond to their environment. First recognized two centuries ago, comas can be deadly because of damage to the brainstem. II. Comas are caused by various reasons, like
I. General Description Trypanosoma cruzi, a protozoan parasite, causes Chagas disease, a zoonotic disease that can be transmitted to humans by blood-sucking triatomine bugs (also known as the kissing bug because it bites on the face). Chagas disease is named after the Brazilian physician Carlos Chagas, who discovered the
Parasite (s) Introduction: A parasite is an organism which lives on/in a host organism and gets its food and makes its living at the host’s expense. Parasites can cause disease in humans and animals. Some parasitic diseases are easily treated while treating others is not that easy. In regard to the size, parasites range from one-celled microscopic organisms (protozoa) to quite large organisms which could be seen by naked eye (worms). Mode of infection: The infection with parasitic diseases varies
The Relationship between Migration and Disease in Africa during European Imperialism During the era of European Imperialism, from approximately 1880 to 1930, an increasing number of Europeans began to colonize West Africa. Because of this colonization many African natives migrated eastward, inadvertently transporting diseases to which the East Africans were not immune (Ransford 76). This phenomenon can be explained through examining the implications of geographical isolation, the effects of
African Medicine The 21st century has begun with a global health crisis of new and re-emerging diseases spiralling out of control, which coupled with escalating violence and poverty, threatens to cripple entire communities and countries. To tackle this crisis, it is currently essential that the Medical community work to access and harness as many resources and partners as possible. One of the resources often overlooked and underestimated, is the role of traditional medicine and healers
Diseases Diseases are any harmful change that interferes with the normal appearance, structure, or function of the body or any of its parts. Since time immemorial, disease has played a role in the history of societies. It has affected and has been affected by economic conditions, wars, and natural disasters. An epidemic of influenza that swept the globe in 1918 killed between 20 million and 40 million people. Within a few months, more than 500,000 Americans died^more than were killed
Africa, you contracted African Trypanosomiasis, better known as sleeping sickness. You contracted this disease from one of the smallest animals you encountered on your safari, the tsetse fly. The tsetse fly carries a parasitic protest known as trypanosoma brucei that causes sleeping sickness. The tsetse fly has helped spread this disease throughout sub-Saharan Africa causing outbreaks that have ravaged populations since the fourteenth century. Symptoms of the disease begin to occur shortly after
Guinea Worm This disease may be on the brink of being eradicated entirely but that doesn’t stop it from being one of the grossest things that anyone has ever seen. The parasite enters the body via unsafe drinking water. When people drink water infected with water fleas that have have been hosting the larvae of the parasite. There are no symptoms, to begin with, but about one year later, blisters on the feet or legs begin to develop and then the adult fully developed worm crawls out of the host
Parasites and their Virulence Why do some parasites kill the host they depend upon while others coexist with their host? Two prime factors determine parasitic virulence: the manner in which the parasite is transmitted, and the evolutionary history of the parasite and its host. Parasites which have colonized a new host species tend to be more virulent than parasites which have coevolved with their hosts. Parasites which are transmitted horizontally tend to be more virulent than those transmitted
