We studied the seroprevalence of anti-Toxoplasma antibodies among inhabitants of the Kathmandu Valley, Nepal (location of the capital, Kathmandu) and inhabitants of a village area in Lekhnath City, Kaski District (central Kathmandu), epal. A total of 376 serum samples were collected from apparently healthy participants. Toxoplasma antibodies (IgM and IgG) were detected by enzyme- linked fluorescent assay (ELFA). In the Kathmandu Valley, positive rates for Toxoplasma IgM and IgG antibodies were 1.4% (2/146) and 35.6% (52/146) respectively. In Lekhnath City, positive rates were 2.6% (6/230) for IgM antibodies and 60.4% for IgG antibodies, i.e., comparatively higher than those in the Kathmandu Valley. The higher prevalence of these antibodies in the Lekhnath City village area was associated with animal keeping in almost all households, while in the Kathmandu Valley only a few households kept animals. However, the seroprevalence of anti-Toxoplasma antibodies in these areas was relatively high in each case. Environmental conditions may be responsible for the transmission of Toxo- plasma parasites in both areas.
