Growth curve of P. hominis co-incubated with IPEC-J2 cells. (A) depicts the growth curve with an initial inoculation concentration of 10⁴ cells/mL of P. hominis, while (B) illustrates the response to an initial inoculation of 10⁵ cells/mL of P. hominis. (C) shows the growth curve following an initial inoculation concentration of 10⁶ cells/mL of P. hominis. The y-axis represents the parasite count, and the x-axis denotes the incubation time in hours. The gray squares represent the growth curve results for individual P. hominis, while the black spheres depict the growth curve results when co-incubated with IPEC-J2 cells.
