Example of photograph of a cyst from our experiment.
Most of the cysts observed took on similar nearly circular cross section projections.
Figure 3.
Relationship between the two measured diameters for each cyst.
The effective diameter is computed as the geometric mean of the two measured diameters: .
Figure 4.
Chronic infection diagram of cyst-volume distribution model.
Parasites infect healthy cells and begin replicating, causing the volume of the cyst to increase. The parasites burst at some rate and release new parasites into the system which are capable of infecting new healthy cells.

Figure 5.
Comparison of probability distributions between experimental data and model selection results using the constant growth function: one-parameter models (indices 1–5) and two-parameter models (indices 6–8).
Panels (a) and (b) show the distributions against volumes and panels (c) and (d) show the distributions against effective diameters. See Figure 3 for the definition of the effective diameter. See Table 2 and Figure 6 for definitions of different models.
