Aebp1 KO cells (Aebp1KO 1-3 strains) showed no significant change in C. parvum infection burden after 2 hr of infection (a timepoint for C. parvum sporozoite attachment to and entry of host cells) however, after 24 hr infection, Aebp1 KO cells displayed significantly higher levels of C. parvum infection burden when compared to IEC4.1 cells infected with C. parvum (Figures 6A, B). This evidence concerns the gene AEBP1 and infection.
