We investigated whether the infection with Trypanosoma cruzi in rats could produce functional alterations of the central nervous system. The experimental group received an injection of 150,000 trypomastigotes / rat, whereas the control group received a saline injection. Spontaneous alternation behavior (SAB) tests and sleep-wake cycle recordings were obtained at the end of the parasitaemia. Results showed that the infected animals had significant sleep impairments, as denoted by an increase in the number of wake periods and a reduction of rapid eye movement sleep amount. SAB performance was also found to be impaired in these animals, as compared to the control group. Our results suggest that the rat is a suitable model for brain dysfunction studies in Chagas' disease.

The Polymerase Chain Reaction (PCR) test is a highly sensitive, specific, and rapid diagnostic tool for Chagas disease. Chagas disease is caused by the protozoan flagellate and is endemic to the Americas. While conventional serological methods are still used in the diagnosis of Chagas disease, they are being gradually replaced by molecular methods like PCR.

Background: Endemic in more than 20 countries, Chagas disease affects 6.3 million people worldwide, leading to 28,000 new infections and 7700 deaths each year. Previous meta-analyses on antiparasitic treatment need updates to encompass recent studies and to assess key clinically meaningful endpoints.

Background: Nurses provide essential care for symptomatic chronic Chagas disease carriers, caused by Trypanosoma cruzi, offering crucial support, symptom management, medication administration, and monitoring to enhance their health-related quality of life.
Objective: To increase healthcare professionals' awareness of the critical role played by high-quality care in the management of patients with chronic Chagas disease.
Methods: This scoping review employed the PRISMA-ScR method as a framework for article selection.
Eco-epidemiological Survey of Trypanosoma cruzi in Dogs from Mendoza, Argentina.

Urban domestic dog populations can provide important clues about the eco-epidemiological characteristics of Trypanosoma cruzi, the causative agent of Chagas disease (ChD). Given the limited data on ChD from the Metropolitan Area of Mendoza, Argentina, a seroprevalence survey of 327 dogs across an urban-rural gradient was conducted between April 2018 and May 2019. Seropositive cases were analyzed considering host, social, and environmental factors, subtypes (DTUs), and bloodstream parasite load.
