Recurrent toxoplasmosis.

A case of recurrent toxoplasmosis in a previously healthy 34-year-old woman is reported. Although she was treated 3 times with co-trimoxazole, which in our experience has been efficient in the treatment of toxoplasmosis, and responded to treatment clinically and serologically, she relapsed with clinical symptoms and rise of anti-toxoplasma titres. Hypothetically, toxoplasmosis is a latent infection which can be activated by other diseases and by immunodepression.
