Short communication: investigation of Toxoplasma gondii antibodies in blood donors by Sabin-Feldman Dye Test

In this study, a serological survey of Toxoplasma gondii infection in healthy blood donors admitted to Blood Center of Ministry of Health, Ankara Training and Research Hospital was carried out. Sera from 390 male and 24 female (ages between 18-59 years) were evaluated by using Sabin Feldman Dye Test (SFDT). Of 414 donors 176 (42.5%) were found positive for T. gondii antibodies. Among the seropositive cases, 106 (25.6%) had 1/16, 40 (9.7%) had 1/64, 28 (6.8%) had 1/256, and two (0.5%) had 1/1024 SFDT titers. The seropositivity rates for females and males were found as 62.5% and 41.3%, respectively, and there was no statistically significant difference (p=0.053). A statistically significant increase was detected in the seropositivity rates with age, 39% being under the age of 40 (18-39 years), 54% over the age of 40 (p
