Toxoplasma gondii

Toxoplasma gondii is an important pathogen in the immunocompromised population and in pregnant women. After initial infection, cysts form specifically in brain and muscle tissue where they persist for the remainder of the host’s life. All Toxoplasma gondii products are RH strain and produced in mice with the exception of NF1011-TC, which is produced in tissue culture.

Trypanosoma cruzi (Chagas)

Trypanosoma cruzi is transmitted to humans by the Reduviid bug. Infection causes the host to contract Chagas disease, or American trypanosomiasis, which is an important cause of cardiovascular and gastrointestinal disease in South America. These antigens are a cocktail of three geographically distinct strains.
