National Seroprevalence of Toxoplasma gondii in India

This article reports the first national serological prevalence of Toxoplasma gondii in India. In total, 23,094 serum samples were tested for T. gondii IgG and IgM antibodies with the use of a solid-phase immunocapture ELISA. Antibodies (IgG) were found in 24.3%; IgM antibodies were detected in 2% of the samples. The lowest seroprevalences were in the northern parts of India, with the highest in the south. These data probably reflect the effects of significantly drier conditions and, therefore, a negative impact on the survivability of T. gondii oocysts.
