Serological and molecular investigation of viral agents in free-living jaguars of the Pantanal wetlands, state of Mato Grosso, Brazil
This study investigates the exposure of free-living jaguars from two federal protected areas in the Pantanal of Mato Grosso, Brazil, to a variety viral agents. These viral agents, particularly causing zoonotic diseases, were analyzed using serological and molecular methods. None of the jaguars was...
