The Puentes Consortium

The Puentes Consortium is intended to provide a distinctive voice for the binational community of scholars who carry out multi-disciplinary research on issues of importance to the relations between Mexico and the U.S. and to the well-being of their inhabitants. Participating universities include Monterrey Tec (ITESM), the University of Monterrey (UDEM) and the University of the Americas in Puebla (UDLAP) in Mexico, and the University of Arizona and Rice University in the United States.

Detection of Latent TB among Migrant Farmworkers

One-third of the world’s population is infected with latent TB (LTBI). Along the Mexico-Arizona border, LTBI is diagnosed using the tuberculin skin test (TST). Cross reactive responses due to BCG vaccination or environmental mycobacteria can lead to false positive results, leading to unnecessary follow-up. New methods of detection more specific than TST have been developed, such as Quantiferon TB gold In-Tube (QFT-GIT). Our objective is to demonstrate utility and feasibility of the QFT-GIT test to detect LTBI among border populations.
