New clues may aid control of T. gondii

Genomic analysis of widespread Toxoplasma parasite identifies proteins that enable parasite to influence host defenses.

U.S. Department of Agriculture scientists and colleagues have provided new clues about the virulence of Toxoplasma gondii — the most widespread parasite in the world. The study described mechanisms involving genetic expression that help a mild T. gondii strain turn aggressive.

For the study, a consortium of international researchers, including zoologist Benjamin Rosenthal and parasitologist Jitender Dubey, contributed strains of T. gondii from more than a
