SEM images of T. gondii tachyzoites recovered from peritoneal fluid of infected mice: (a & b) Non treated tachyzoites showing typical crescent shape and smooth body with intact regular membrane (x15,000); (c & d) SPI-treated tachyzoites showing minimal changes in the form of mild irregularities and few dimples on the crescent shape surface (x15,000); (e-f) MNPs-treated tachyzoites showed (e) markedly distorted body with multiple deep ridges and furrows (x15,000); (f) shrunken body and obvious protrusions (x15,000); (g-h) nZVI-treated tachyzoites showed (g) distortion of the posterior end with plasma membrane erosions and ulcerations (x15,000); (h) external protrusions and dimples (x15,000).
