Fig. 1) although the direction and intensity of selection for aggressiveness will depend on any associated fitness costs (V. Fig. 1).

Factors relating to host (impairment of local immunity) and to M. hominis (essentially selection of immune escape mutants and perturbation of the host cell) have been suggested as a basis for the disruption of the host-pathogen equilibrium and the appearance of clinical disorders [ 25].
