Parasite recovery and yield efficacy

Step	Recovered parasitic stage	Quantity of parasites after each stepa	Yield (%)a,b
Cleaning of oocysts with 1-μm filterc	Oocysts	1.19 ± 0.13 × 105	79.44 ± 9.17
Oocysts mechanical grind with glass beads	Sporocysts	3.33 ± 0.55 × 105	55.55 ± 9.17
Excystation	Sporozoites	4.46 ± 0.9 × 105	39.02 ± 7.50
Sporozoites purification with 5-μm filter	Sporozoites	4.28 ± 1.07 × 105	35.69 ± 8.93

^aQuantities and yields reported are the means ± standard deviations of triplicate

^bYield percentages calculated from an initial amount of 1.5 × 10⁵ oocysts

^cYield percentages of earlier steps during oocysts cleaning were not calculated
