Although in the experiments, slender, intermediate and stumpy cells were counted, we choose to include intermediate cells in the stumpy class.
And increasing slender to stumpy transition period causes behaviour similar to monomorphic trypanosome strains.
In both cases, an increased transition period (dotted lines) prevents oscillations and delays the occurrence of stumpy cells.
It predicts many facets of slender to stumpy transformation that are testable.
Values for the morphometric parameters indicated a position between the slender and the stumpy forms.
At least 250 trypanosomes were examined and classified as slender, dividing, intermediate or stumpy forms.
The only major difference is that when a2=0, stumpy cells appear a little later in the simulation.
One subpopulation that differentiated at the background rate into intermediate cells but never fully developed into stumpy cells.
