Frequency of Sero-Positive Blood Donors for Toxoplasmosis as observed in Queen Alia Hospital, Amman, Jordan.
J Coll Physicians Surg Pak Jan ;10(4):140-2.

Toxoplasmosis is a parasitic infection caused by an obligate intracellular protozoan, Toxoplasma gondii. Most of the toxoplasma infections are asymptomatic or benign, but may cause severe or fatal consequences in immunodeficient patients, transplant recipients and in the fetus. Transmission may occur by eating uncooked meat, contaminated vegetables, blood transfusion, organ transplantation and across the placenta from mother to the fetus. Antibodies to T. gondii may persist in the serum at high titer for years. We undertook this study to determine the actual frequency of toxoplasma antibody in Jordanian blood donors at Queen Alia Hospital, Amman, Jordan. We screened 931 donors by using indirect immunofluorescence antibody test, out of which 387 (41.5%) were found to be seropositive for T. gondii at different titers. The highest frequency of seropositivity was found in the age group ranging from 21 to 35 years in male blood donors. Among female blood donors the higher rate of seropositivity was found in the age group 21-30. The titer of antibodies declined after 40 years of age in most of the subjects included in this study.
