The DRG Toxoplasma gondii IgM Enzyme Immunoassay Kit provides materials for the quantitative and qualitative determination of IgM-class antibodies to Toxoplasma gondii in human serum and plasma.This assay is intended for in vitro diagnostic use only.Toxoplasma gondii is a small intracellular parasite, whose life cycle has a sexual and an asexual phase. Sexual development is restricted to the intestinal cells of (probably exclusively) cats; the oocysts formed are excreted and due to their resistant cell walls they may be infectious under advantageous circumstances for at least 1 year. Animals and man are intermediate hosts for the asexual proliferation of T. gondii: the ingested parasites will proliferate explosively within the host cells lysing them eventually. They disseminate throughout the body via circulation and lymphatic system and may infect any cell type. About half of the Toxoplasma infections process clinically inaparent. The other Toxoplasma infections show often only unspecific symptoms, after an incubation time from one to three weeks with lightly fever, exhaustion, headaches well as muscle and joint pain. Complications in the form of myocarditis, meningitis or pneumonia occur at 1% of infected children and young adults respectively. After recovery, Toxoplasma gondii cells persists in infected tissues by forming cysts which are resistant to the attacks of the immune system. In immunocompetent individuals the latent infection does not reactivate. After suppression of the immune system, activation of latent infections has been observed and can lead to severe complications.
