Additionally, repeat serology confirmed markedly elevated Toxoplasma gondii IgG (>500 IU/mL) with negative IgM, together with positive EBV IgG (32.7; cutoff > 11) and negative IgM, further supporting the diagnosis of concomitant toxoplasmosis and EBV coinfection. This evidence concerns the gene CD40LG and toxoplasmosis.
