Tachyzoite forms of Toxoplasma gondii were subjected to a sequential organic solvent extraction, which allows fractionation of membrane components according to their degrees of hydrophobicity, yielding three fractions named F1 (most hydrophobic) to F3 (least hydrophobic). Fractions F2 (80.85% specificity and 86.95% sensitivity) and F3 (89.36% specificity and 93.61% sensitivity) gave the best results, being preferentially recognized by immunoglobulin M (IgM) and IgG in sera from patients with… CONTINUE READING
