TOXOPLAMOSIS TRANSMITTED TO NEWBORN FROM MOTHER
INFECTED 20 YEARS PRIOR
ABSTRACT
Purpose: To present a case of congenital toxoplasmosis in a newborn of a mother
with a 20 year history of a chorioretinal macular scar and a positive serology for
toxoplasmosis.
As far as we know this is the first case in which a child with congenital
toxoplasmosis and macular involvement was born to a mother infected years before.
Design/Methods: case report
Setting/Results: A 38 years old female, who had been treated for ocular
toxoplasmosis 20 years before, delivered a newborn who presented with a focal necrotizing
retinochoroiditis characteristic of toxoplasmosis, and in addition had positive IgG and IgM
serology for toxoplasmosis. The workup was negative for other entities including
lymphochoriomeningitis virus, syphilis and Herpes simplex and zoster.
Conclusion: This case suggests that, contrary to the literature women with old
retinal scars due to toxoplasmosis, and longstanding circulating IgG antibodies to
toxoplasmosis, are also at risk of transmitting this disease to the fetus.
