Revista do Instituto de Medicina Tropical de São Paulo, 1999 We describe the avidity maturation of IgGs in human toxoplasmosis using sequential serum samples from accidental and natural infections. In accidental cases, avidity increased continuously throughout infection while naturally infected patients showed a ...
