FIG 3.

Spectrophotometric analysis of crystal violet absorbance by IPEC-J2 monolayers following coculture in the absence (IPEC-J2) or presence of feline T. foetus (IPEC-J2 + T. foetus) or feline P. hominis (IPEC-J2 + P. hominis) for 36 h. Data represent n = 6 cultures per treatment and are reported as means ± SD. P < 0.05 (*) and P < 0.001 (***) compared to uninfected IPEC-J2 monolayers; ***, P < 0.001 for T. foetus-infected monolayers compared to P. hominis-infected monolayers. (Determined by one-way ANOVA and post hoc Holm-Sidak test.) Representative wells of each treatment condition after staining with crystal violet are below the column of each treatment group.
