Foy Lab

The Foy lab is conducting a field study that will test a new method to control the transmission of West Nile Virus around Northern Colorado households. Interested in participating? Check out this flyer for more information.

As a member of the Center for Vector-Borne Infectious Diseases (CVID) at Colorado State University, the Foy laboratory focuses on the interactions of vectors with their hosts and with vector pathogens. The goal is to link research employing molecular, proteomic and genomic techniques to practical applications for controlling arthropod-borne diseases. A main research component in the Foy lab is to interrupt the intense transmission of malaria and arboviruses by targeting the vector through their bloodmeals using drugs that attack vector physiology and that inhibit pathogen development or using anti-vector immunity driven by vaccination. The Foy lab is also developing mosquitoes and other vectors as biosurveillance tools, studying unique aspects of arbovirus transmission and arbovirus survival in vectors, and studying poorly understood mosquito pathogens for their prospects to become vector-borne disease control tools. The Foy lab is also a part of the Rockies and High Plains Vector-borne Diseases Center, a regional training and evaluation center funded by the CDC where Brian Foy serves as co-director.

research project

Repeat Ivermectin Mass Drug Administrations for Malaria control II (RIMDAMAL II)

This is a cluster randomized clinical trial in Burkina Faso to test whether repeated ivermectin mass drug administrations, integrated into a monthly delivery platform with standard malaria control measures of seasonal malaria chemoprevention and insecticide-treated bed net distribution, will reduce childhood malaria incidence and limit resistance development in mosquitoes and parasites.

research project

TRANSMIT: Tracking Antimalarial Resistance in Mosquito Populations

This project is designed to compare malaria parasite drug resistance tracking techniques using human blood samples versus using captured blood fed mosquito samples.

research project

Comparison of mosquito age-grading measures in the RIMDAMAL II randomized, double-blind clinical trial

This project is comparing new and old mosquito age grading techniques within the context of our RIMDAMAL II clinical trial to best determine how different vector-control measures mosquito population age structure.

research project

Aedes-borne arbovirus transmission

We are studying humans and animal models to characterize the viral dynamics, host responses and disease outcomes resulting from Aedes-borne arbovirus transmission. We are especially interested in understanding these outcomes from Zika virus transmission by the sexual and mosquito-borne routes. Our human studies partners are researchers at FIOCRUZ, Aggeu Magalhaes Institute, Recife, PE, Brazil.

research project

Endectocides for West Nile virus control

This project designed to develop and test endectocide-treated bird feed for efficacy in controlling West Nile virus transmission. Our partners are colleagues at UC-Davis, CDC-DVBD, and TDA Research, Inc.
