Toxoplasmic retinochoroiditis appears to be more severe in Brazil, where it is a leading cause of blindness, than Europe, but direct comparisons are lacking. Evidence accumulating that virulent genotypes Toxoplasma gondii predominate South America.We compared prospective cohorts children with congenital toxoplasmosis identified by universal neonatal screening Brazil and or prenatal Europe between 1992 2003, using the same protocol both continents.Three hundred eleven (311) had toxoplasmosis:...

to investigate the rate of positivity for immunoglobulin M anti- Toxoplasma gondii (Toxo-IgM) in newborns with congenital toxoplasmosis, and age when these antibodies become negative. patients toxoplasmosis who started monitoring a infection clinic between 1998 2009 were included. Inclusion criteria routine maternal or neonatal serological screening; diagnostic confirmation by persistence G at ≥ 12 months, Toxo-IgM screening period. To calculate frequency positive Toxo-IgM, cases detected...
