The biological mothers of 23 patients presenting with acute chorioretinal toxoplasmosis had sera screened for the presence of antibodies to Toxoplasma gondii. Twenty-two of the mothers (96%) had positive serology and one (4%) had negative serology. This is consistent with the hypothesis that most cases of ocular toxoplasmosis are congenital in origin, but indicates that some cases are due to acquired toxoplasmosis.
