Chagas disease is a disease caused by the parasite Trypanosoma cruzi. It is caused by the parasite Trypanosoma cruzi, which is transmitted to animals and people by insect vectors and is found only in the Americas (mainly, in rural areas of Latin America where poverty is widespread). Reduced cardiac pumping ability can cause significant weakness and fatigue. cruzi is a protozoa parasite, a pathogen that causes injury to an organ which it colonizes, greatly enlarging it, by denervating its nerve and muscle tissues. The acute phase is usually symptom-free, but infected people may have mild signs and symptoms. Genus- Trypanosoma. Chronic phase presents itself after 30-40 years later and about 30-40% of the infected individuals develop severe cardiac or digestive complications [3,4].

One-third of those infected with T. cruzi eventually develop 62 Chagasic pathology, although symptoms can take decades to become apparent. 1. There are many symptoms to this and the symptoms vary over time with the infection. [1] Infektion av Trypanosoma cruzi är kronisk och en minoritet av de som bär på parasiten utvecklar Chagas sjukdom, ett sjukdomstillstånd som kan leda till döden. Only $1/month. Symptoms of Chagas' disease may begin within a few days to a few weeks after infection. First signs and symptoms are observed a few months or weeks after infection. 3. The disease caused by this parasite is called "Chagas disease" or "South American trypanosomiasis". Trypanosoma cruzi - Chagas disease. Chagas disease, also known as American trypanosomiasis, is a tropical parasitic disease caused by Trypanosoma cruzi.It is spread mostly by insects in the subfamily Triatominae, known as "kissing bugs".The symptoms change over the course of the infection. The two main lineages that are specifically linked to the disease are T. Cruzi I and T. Cruzi II [2]. First signs and symptoms are observed a few months or weeks after infection. THE PARASITE — Trypanosoma cruzi A parasite called Trypanosoma cruzi causes Chagas disease. This type of disease typically occurs in south and central America which are the people that are mostly at risk for developing this disease, this disease could affect anyone that are there, there are no specific age group or gender that are higher at risk. This behaviour causes disease or the likelihood of disease that varies with the organism: Chagas disease in humans, dourine and surra in horses, and a brucellosis-like disease in cattle. the protozoan parasite, Trypanosoma cruzi (Chagas, 1909). The acute phase is usually symptom-free, but infected people may have mild signs and symptoms. Although diagnosis is important to prevent possible chronic manifestations of the disease (eg, cardiomyopathy), the diagnostic process may be complicated by a lack of symptoms in the acute and chronic phases. Treatment includes a variety of self-care measures and over-the-counter medications. Elsevier; 2012;12: 240-253. The vector for the transmission of Trypanosoma cruzi infection is the Reduviid bug (it is also called the kissing bug or assassin bug).This bug transmits Trypanosoma cruzi infection when it feeds on humans at night while they sleep; it will then defecate as it feeds . Chagas disease presents an asymptomatic initial phase, but symptoms appear later and can present in different forms, such as fever, anorexia, myocarditis, weight loss, cardiomyopathy, dementia and even death if not treated. Swollen eyelids, if the parasite has entered through the eyes (known as Romaña's sign) These early symptoms -- if they happen at all -- usually fade on their own in a few weeks or months. 63 Cardiomyopathy is the most common clinical outcome (6-8), followed by digestive tract 64 megasyndromes, which are reported in about 10% of infected individuals, often in Chagas disease is a major cause of heart disease in Latin America, caused by an infection with Trypanosoma cruzi (T. cruzi), a protozoan parasite. They might be hard to tell apart from other illnesses. Congenital T. cruzi infection occurs in 1-10% of infants of infected mothers. On examination, your veterinarian may observe signs of heart failure, fluid in the abdomen, and lymph node enlargement. Chagas disease is caused by a parasite called Trypanosoma cruzi, a common parasite in Central and South America. Trypanosoma cruzi, a protozoan hemoflagellate, is the parasite that causes this disease.
