Survival curves of immunized mice after Toxoplasma gondii challenge infections.
Notes: BALB/c mice were challenged intraperitoneally with 1×103 tachyzoites of T. gondii RH strain (PBS or Exo-R group) or ME 49 strain (Blank or Exo-M group) 2 weeks after the final immunization (n=10 animals per group). Survival times were monitored daily and the comparison of differences between the experimental group and the control group was significant (p<0.05). These data are representative of three experiments with similar results.
Abbreviations: Exo-R, exosomes from RH strain; Exo-M, exosomes from ME 49 strain; PBS, phosphate buffered saline.
