Trypanosoma cruzi

(redirected from T cruzi)

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 brought in contact with mucosal surfaces. Trypomastigotes are found in the blood, and amastigotes occur intracellularly in clusters or colonies in the tissues; heart muscle fibers and cells of many other organs are attacked, the organisms not being restricted to macrophages as in visceral leishmaniasis; humans, dogs, cats, house rats, armadillos, bats, certain monkeys, and opossums are the usual vertebrate hosts; vectors are members of the family Triatominae. Also known as Schizotrypanum cruzi, a distinct generic designation widely used in the endemic regions.

(trī-pan'ō-sō'mă krūz'ī)
A species of protozoan flagellates that causes South American trypanosomiasis; transmission and infection are common only where the triatomine bug vector defecates while taking blood, because the bug feces contain the infective agents that are scratched into the skin or brought in contact with mucosal surfaces. Trypomastigotes are found in the blood; heart muscle and other organs are attacked.

Trypanosoma cruzi

The causative agent of American trypanosomiasis (Chagas disease). It is transmitted by triatomids (bloodsucking insects of the family Reduviidae).

In October 2016, an 18-year-old US Air Force trainee screened positive for T cruzi infection when he donated blood at Joint Base San Antonio (JBSA), Texas.
Sin embargo, T cruzi logra tambien infectar al hospedador vertebrado oralmente mediante la ingesta de alimentos contaminados, por transfusion de sangre proveniente de donadores infectados, congenita o transplacentariamente de madres infectadas a sus crias o por trasplantes de organos infectados [1,5,9,15,21,25].
La Reaccion en Cadena de la Polimerasa (PCR), mediante el empleo de los primers S35-S36, ha permitido la deteccion de T cruzi en tejidos infectados con cepas I y II del parasito y ha sido utilizada para monitorear pacientes con cardiomiopatia chagasica.
Bugs of the species T sanguisuga are responsible for the first described autochthonous case of T cruzi transmission in Louisiana (6), but little is known about their feeding habits in natural conditions.
Sin embargo, el ensayo de PCR anidada (PCR-A) (10), el ensayo de PCR cuantitativa en tiempo real (PCR-RTQ) (11), y el ensayo de oligocromatografia (OligoC) (12) se han realizado para mejorar la deteccion de ADN de T cruzi.
Se estudio, el efecto de la preincubacion por una hora a temperatura ambiente, de extractos proteicos de aislado de T cruzi, con 200 [micron]M E64, se analizo el efecto mediante zimografia en gel, usando buffer formiato a pH 2,9 como ha sido descrito.

The Food and Drug Administration (FDA) has published a draft guidance that would require all tissue banks and blood centers to use serological tests of all donations of Human Cells, Tissues, and Cellular Tissue-Based Products (HCT/Ps), and allogenic blood donations for antibodies to T cruzi (Trypanosoma cruzi), the parasite that causes Chagas disease (trypanosomiasis).
cruzi blood trypomastigotes infect macrophages actively, its internalization by the macrophages may be just a consequence of the action of the T cruzi itself, which is related to its virulence.
No obstante, para modelar los datos y encontrar los factores que en su conjunto pudieran explicar la seropositividad a anticuerpos contra T cruzi, tambien se incorporaron al modelo logistico las variables con valores de P < 0,20: reconocer las chinches (P = 0,09), que los animales durmieran dentro del domicilio (P = 0,09), escasa ventilacion del dormitorio (P = 0,20), presencia de fisuras en el techo (P = 0,10), encontrar chinches fuera de la casa (P = 0,09) y no rociar insecticidas habitualmente (P = 0,14) (cuadro 7).
2) After previous studies performed in eastern Colombia on T cruzi infection, (3) we found a new cross-reaction for HIV that had never been described before.
