Treatment ID:	TR002661
Treatment Summary:	To generate cysts for infection, 8-10 week female CBA/J mice were infected with 10 Me49 bradyzoite cysts by intraperitoneal injection. 4–8 weeks following infection, mice were euthanized by CO2 inhalation and cysts were harvest from brains homogenate passed through a 70 μm filter. Homegenate was washed 3 times in PBS, stained with dolichos biflorus agglutinin conjugated to FITC (Vector labs) at a 1:500 dilution. The number of cysts were determined by counting FITCpositive cysts at 20x magnification using an EVOS FL imaging system (Thermo Fisher). For experimental infections 10–14-week-old male C57BL/6 mice were infected with 10 Me49 bradyzoite cysts by intraperitoneal infection resuspended in 200 Μl PBS per mouse using a 5G 5/8” tuberculin syringe. Prior to infection, mice were cross-housed on dirty, wood chip bedding for two weeks to normalize commensal microbiota and limit the effect of eating corn husk bedding on dietary metabolites. At experimental endpoints, mice were fasted for 4 hours and isoflurane anaesthetized to isolate sera via retro-orbital bleed and/or euthanized by CO2 asphyxiation to harvest tissues for weighing and histological analysis.
