Biology of Trypanosoma cruzi: An update [PDF]

Infectio, 2012
AbstractChagas disease, an illness caused by the protozoan Trypanosoma cruzi, is clinically and epidemiologically important in Latin America, and particularly in Brazil. This article presents the main biological characteristics of Trypanosoma cruzi, emphasizing ultrastructural, morphological, evolutionary, transcriptomic, and proteomic aspects.

Priming astrocytes with TNF enhances their susceptibility to Trypanosoma cruzi infection and creates a self-sustaining inflammatory milieu

Journal of Neuroinflammation, 2017
Background In conditions of immunosuppression, the central nervous sty 5ystem (CNS) is the main target tissue for the reactivation of infection by Trypanosoma cruzi, the causative agent of Chagas disease. In experimental T.

Habitat Management to Reduce Human Exposure to Trypanosoma cruzi and Western Conenose Bugs (Triatoma protracta). [PDF]

, 2016
Chagas disease, which manifests as cardiomyopathy and severe gastrointestinal dysfunction, is caused by Trypanosoma cruzi, a vector-borne parasite. In California, the vector Triatoma protracta frequently colonizes woodrat (Neotoma spp.) lodges, but may ...

Mexican Trypanosoma cruzi T. cruzi I Strains with Different Degrees of Virulence Induce Diverse Humoral and Cellular Immune Responses in a Murine Experimental Infection Model

Journal of Biomedicine and Biotechnology, 2010
It is has been shown that the majority of T. cruzi strains isolated from Mexico belong to the T. cruzi I (TCI). The immune response produced in response to Mexican T. cruzi I strains has not been well characterized. In this study, two Mexican T.

Infectivity of amastigotes of Trypanosoma cruzi [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 1986
The infectivity amastigotes of Trypanosoma cruzi, isolated from the supernatant of the J774G8 macrophage-like cell line infected with trypomastigotes to normal macrophages in vitro was tested. After a period of 1 h of T. cruzi-macrophage interaction about 2% of the mouse peritoneal macrophages had ingested amastigotes.

Eco-epidemiological study of an endemic Chagas disease region in northern Colombia reveals the importance of Triatoma maculata (Hemiptera: Reduviidae), dogs and Didelphis marsupialis in Trypanosoma cruzi maintenance

Parasites & Vectors, 2015
Background In Colombia, Rhodnius prolixus and Triatoma dimidiata are the main domestic triatomine species known to transmit T. cruzi. However, there are multiple reports of T. cruzi transmission involving secondary vectors.

Vector-borne transmission of Trypanosoma cruzi among captive Neotropical primates in a Brazilian zoo [PDF]

, 2016
Background: Neotropical primates are important sylvatic hosts of Trypanosoma cruzi, the etiological agent of Chagas disease. Infection is often subclinical, but severe disease has been described in both free-ranging and captive primates.

Killing in vitro of Trypanosoma cruzi by macrophages from mice immunized with T. cruzi or BCG, and absence of cross-immunity on challege in vivo

Journal of Experimental Medicine, 1975
Peritoneal macrophages from T. cruzi-immune mice were resistant to infection in vitro with culture forms of the parasite. Macrophage resistance appeared in infected mice about 21 days postinfection when parasitemia was still rising.

High incidence of Trypanosoma cruzi infections in dogs directly detected through longitudinal tracking at 10 multi-dog kennels, Texas, USA

PLoS Neglected Tropical Diseases, 2021
Canine Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, is increasingly recognized as a health concern for dogs in the USA, and infected dogs may signal geographic regions of risk for human disease.

Effectiveness of Systemic Insecticide Dog Treatment for the Control of Chagas Disease in the Tropics

Biology, 2023
Chagas disease, caused by Trypanosoma cruzi and transmitted by triatomines, can lead to severe cardiac issues and mortality in many mammals. Recent studies have shown that systemic insecticide treatment of dogs is highly effective in killing triatomines.
