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.

Evaluating the reliability of a microperimetry-based method for assessing visual function in the junctional zone of geographic atrophy lesions.

Purpose: To assess the repeatability of a microperimetry methodology for quantifying visual function changes in the junctional zone of eyes with geographic atrophy (GA) in the clinical trial context.

Methods: A post hoc analysis of the OAKS phase III trial was conducted, which enrolled patients with GA secondary to age-related macular degeneration. Microperimetry using a standard 10 - 2 fovea centered grid was performed at baseline and follow-up visits.

The Laboratory Opossum () Is a Unique Model for Research on Zika Virus: Robust Immune Response, Widespread Dissemination, and Long-Term Persistence.

The Zika virus (ZIKV) epidemic elicited a rapid commitment to the development of animal models for ZIKV research. Non-human primates (NHPs) and mice have made significant contributions to this research, but NHPs are expensive, have a long gestation period, and are available only in small numbers; non-genetically modified mice are resistant to infection. To address these deficiencies, we have established the laboratory opossum, , as a small animal model that complements the mouse and monkey models.
