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). Chagas disease ( T. cruzi infection) is also referred to as American trypanosomiasis Trypanosoma cruzi, is a parasitic protozoan that is the causative agent of Chagas disease (American trypanosomiasis). Currently, six distinct lineages of T. cruzi are classified into discrete typing units (TcI-VI), which vary in their geographic occurrence, host specificity, and pathogenicity. Life Cycl Chagas disease, also known as American trypanosomiasis, is a potentially life-threatening illness caused by the protozoan parasite Trypanosoma cruzi (T. cruzi).. About 6 million to 7 million people worldwide are estimated to be infected with Trypanosoma cruzi, the parasite that causes Chagas disease.Chagas disease is found mainly in endemic areas of 21 continental Latin American countries 1. Trypanosoma Cruzi (T. Cruzi) is a kinetoplast eukaryotic cell that is associated with causing the often fatal Chagas Disease, which spreads through insects . The two main lineages that are specifically linked to the disease are T. Cruzi I and T. Cruzi II  Trypanosoma cruzi. American Trypanosomiasis, commonly known as Chagas' disease, presents one of the highest disease burdens in Latin America. Approximately 16-18 million people are currently infected, 50,000 of which die each year. The social and economic impact of morbidity is substantial

Chagas disease is caused by the protozoan parasite Trypanosoma cruzi and affects over 6 million people worldwide. Development of new drugs to treat this disease remains a priority since those currently available have variable efficacy and frequent adverse effects, especially during the long regimens required for treating the chronic stage of the disease Author summary Chagas disease is a neglected zoonosis of growing concern in the southern US, caused by the parasite Trypanosoma cruzi. Here we analyzed the parasite genetic diversity in a large cohort of infected dogs to better understand parasite transmission cycles and assess potential relationships between parasite diversity and serological test performance Trypanosoma cruzi is an intracellular trypanosomatid protozoan, which is transmitted to the human host by blood-feeding reduviid bugs, members of the insect subfamily Triatominae. Other modes of transmission include oral infection through contaminated food, congenital transmission, blood transfusions, organ transplants, and by accidental.
Try·pan·o·so·ma cru·zi a species that causes South American trypanosomiasis and is endemic in Mexico and various countries of Central and South America; transmission and infection are common only where the triatomine bug vector defecates while taking blood, because the bug's feces contain the infective agents that are scratched into the skin or. The study in cultures of human cells infected with Trypanosoma cruzi (T. cruzi), the parasite that causes Chagas disease, suggests that its metabolic state influences the effectiveness of azole. Trypanosoma is a genus of kinetoplastids (class Trypanosomatidae), a monophyletic group of unicellular parasitic flagellate protozoa.Trypanosoma is part of the phylum Sarcomastigophora. The name is derived from the Greek trypano-(borer) and soma (body) because of their corkscrew-like motion. Most trypanosomes are heteroxenous (requiring more than one obligatory host to complete life cycle) and. Trypanosoma cruzi, an important zoonotic protozoan that causes Chagas disease, affects at least 8 million people in Latin America. Chagas disease is an important life-long infection in humans that can be divided into distinct clinical stages: the acute phase, where patient symptoms can vary from asymptomatic to severe; the indeterminate form, which is usually asymptomatic; and the chronic.

Frontiers in immunology 4:1-10 Trypanosoma cruzi is a protozoan parasite of humans and animals, affecting 10 to 20 million people and innumerable animals, primarily in the Americas. Despite being the largest cause of infection-induced heart disease worldwide, even among the neglected tropical diseases (NTDs) T. cruzi is considered one of the least well understood and understudied Trypanosoma cruzi is the etiologic agent of Chagas disease, a neglected tropical disease that affects millions of people mainly in Latin America. To establish a life-long infection, T. cruzi must subvert the vertebrate host's immune system, using strategies that can be traced to the parasite's life cycle. Once inside the vertebrate host, metacyclic trypomastigotes rapidly invade a wide. The increasing detection of infections of Trypanosoma cruzi, the etiological agent of Chagas disease, in non-endemic regions beyond Latin America has risen to be a major public health issue. With an impact in the millions of people, current treatments rely on antiquated drugs that produce severe side effects and are considered nearly ineffective for the chronic phase
