 AB    Knowledge of Toxoplasma seroprevalence among human immunodeficiency
       virus-infected patients identifies candidates for potential prophylaxis
       and may influence management among patients who present with mass
       lesions of the central nervous system. Toxoplasma antibody
       seroprevalence among persons with human immunodeficiency virus infection
       varies widely. We utilized an administrative and laboratory database
       (including 1599 patients with human immunodeficiency virus infection who
       were receiving medical care at the University of California-San Diego
       Medical Center, between July 1, 1986, and March 31, 1990) to estimate
       Toxoplasma seroprevalence. Of the 1599 patients, 344 underwent serum
       assays for Toxoplasma antibodies. The tested group was similar to other
       members of the cohort in distributions of sex, race, citizenship, and
       age. The overall mean (+/- SE) Toxoplasma seroprevalence was 16% +/- 2%.
       Potential bias in this estimate because of testing indication,
       misclassification, or testing frequency was small.
