One Health Modeling and Perspective Center
CEMPOH of the Faculty of Veterinary Medicine and Agronomy of Universidad de Las Américas
Our purpose is to develop interdisciplinary research to address emerging challenges related to human, animal, and environmental health, enabling progress in the understanding and promotion of global health.
Research
Research associated with the triggers that affect human, animal, and environmental health to improve preparedness and response to health emergencies.
Outreach
Scientific outreach aimed at promoting a culture of global health in the population.
WHAT DO WE DO?
Here are some of our latest projects
Want to see more?
Functional and biochemical characterization of a putative antibacterial type six secretion system effector of the foodborne pathogen Salmonella Dublin
This project, led by Dr. David Pezoa, seeks to understand how the effector of the antibacterial type six secretion system (T6SS) contributes to the ability of Salmonella Dublin to infect and compete with other bacteria, which will improve knowledge about the virulence and bacterial competition mechanisms of Salmonella. Funding: FONDECYT-ANID
Genetic consequences of deforestation in the Magellanic Woodpecker (Campephilus magellanicus) across its distribution in Chile
The project led by Dr. Yanina Poblete seeks to assess how deforestation patterns shape the genetic structure of the Magellanic woodpecker across its distribution in Chile, in order to contribute information regarding the vulnerability and connectivity of its populations across its distribution in Chile. Funding: Regular Research Projects – UDLA: DI-41/22.
Epidemiology and characterization of influenza A virus in domestic dogs and cats in central Chile
The project led by Francisca Di Pillo seeks to explore the role of pets in the epidemiology of the influenza A virus. Through semi-structured surveys of owners and diagnosis of Influenza A in pets, the project aims to establish risk factors that influence the occurrence of influenza A in pets. Funding: Regular Research Projects – UDLA: PIR202411

Functional and biochemical characterization of a putative antibacterial type six secretion system effector of the foodborne pathogen Salmonella Dublin
This project, led by Dr. David Pezoa, seeks to functionally and biochemically characterize an effector of the type six secretion system (T6SS) of Salmonella Dublin, and to understand its role in infection and bacterial competition. This will expand knowledge about the virulence of Salmonella and contribute to new food safety strategies. Funding: FONDECYT-ANID Iniciación
Granulomatous response led by Gamma delta (gd) T cells against cattle non-fertile Cystic Echinococcosis cyst is disrupted by Fasciola hepatica natural co-infection
In this project, whose principal investigator is Dr. Rodolfo Paredes and where Dr. Christian Hidalgo is co-investigator, tissues infected by Echinococcus granulosus and Fasciola hepatica are investigated, evaluating the innate and adaptive immune response from a histological standpoint. The project seeks to understand the role of gamma-delta T lymphocytes in the pathophysiology of cystic echinococcosis in cattle. Funding: FONDECYT-ANID Regular 1231620.
Wetland Ecosystems Laboratory Transfer: Development of sustainable biotechnological applications for the O’Higgins Region
Led by Dr. Gemma Rojo, with Dr. Christian Hidalgo as co-investigator, this project creates a wetland analysis laboratory for its conservation by the local community. Hidalgo studies snails to assess the presence of trematode parasites as an indicator of wetland health. Funding: FIC O’Higgins Project.
Risk-taking behavior relates to oxidative status and Haemosporidian infection in Zonotrichia capensis
The project, derived from Dr. Yanina Poblete’s postdoctoral research, seeks to assess whether risk-related behavior is related to the occurrence of malaria infection and whether this relationship impacts the oxidative status of wild birds.
Genomic characterization of avian pathogenic Escherichia coli strains isolated from birds from commercial farms and identification of antigens as possible components that could be part of a preventive therapy
The project, whose Principal Investigator is Dr. Leandro Cádiz, aims to characterize the genome of avian pathogenic Escherichia coli strains isolated from poultry…
Subunit oral vaccine against Salmonella Infantis, S. Enteritidis and S. Typhimurium for broiler chicks: Innovation in the functionalization of Carrier particles to improve mucosal and systemic immunity
FONDEF Project, which seeks to generate a product that improves the protection of broiler chickens against 3 serovars of Salmonella enterica via the oral administration route.
