Parasitism and behavioral dominance among male mice.
Infestations by the nematode Heligmosomoides polygyrus can prevent adult male mice from becoming behaviorally dominant. The effect is dose-dependent and is more likely to influence the development of dominance than to disrupt existing dominance relationships. Doses capable of exerting this effect are not lethal and do not affect weight.
