Each plate is coated with Chagas (Trypanosoma cruzi) antigen: a mixture of purified inactivated whole organism. It is a mixture of three strains from different geographical areas (US, Brazil, Argentina). It will cross react with Leishmania.
Chagas disease is caused by a parasite, Trypanosoma cruzi. Typically, the parasite is transferred to humans and animals after being bitten by an insect. The parasite is present in parts of North America, central and Latin America. Infection from Chagas disease can also be known as American trypanosomiasis. Most people affected from this infection can possibly remain asymptomatic and not succumb to any negative symptoms. Approximately 20-30% of cases involving human infection developed complications ranging from abnormal heart rates which can be fatal, irregular pumping of blood through one’s circulatory system, and perhaps a dilated colon or esophagus.
