Molecular and Serological Detection of Acute and Latent Toxoplas¬mosis Using Real-Time PCR and ELISA Techniques in Blood Donors of Rafsanjan City, Iran, 2013 |
|
| چکیده انگلیسی مقاله |
Abstract Background: The differentiation between acute and latent forms of the Toxoplasma gondii ( T. gondii ) infection is still considered as a complicated issue. This study was aimed to elucidate the status of infection in the blood donors and the probable importance of blood transfusion in the transmission of the infection through detecting both immunological and genetic markers of acute and latent infection. Methods : Totally 235 blood samples from blood donors were collected. The levels of anti- T. gondii IgG and IgM antibodies were examined by specific ELISA kits. cDNA were synthesized from total extracted mRNA molecules from the serum samples and SAG1 gene, specific for tachyzoite form, were amplified using Real-Time PCR technique. Demographic information of study subjects including their gender, age, job, and habitat were recorded. Results : Out of 235 serum samples, 80 (34.04%) and 4 (1.71%) were positive regarding anti- T. gondii IgG and IgM antibodies, respectively. Real-Time PCR results showed that 14 out of 200 (6.97%) of blood donor had mRNA molecules of SAG1 gene. The positive results of Real-Time PCR of SAG1 in female gender and housekeepers were significantly higher than those of male gender and other job categories. Conclusion : The prevalence of chronic and acute infection is high in Iranian blood donors. Additionally, evaluation of antibodies could not be reliable, because several donors negative for anti- T. gondii IgM antibodies had detectable SAG1 mRNA molecules. Hence, it seems that molecular diagnostic tests are essential to detect acute infections. Keywords: Toxoplasma , Blood transfusion, Blood donors, Tachyzoite, Iran |
