Laboratory mouse (Mus musculus) morphological responses to Heligmosomoides bakeri and/or Hymenolepis microstoma infection for mice from treatment groups for Experiment 1 (LCN: low cestode infection, then nematode; HCN: high cestode infection, then nematode; N: nematode only) and Experiment 2 (C: cestode only; CN: cestode then nematode; NC: nematode then cestode; SI: simultaneous inoculation; N: nematode only). Values are means ± standard error. For small intestine dry mass for Experiment 2, means that share the same superscript letters are not significantly different from each other at P < 0.05.

^a For Experiment 2, values are backtransformed from Log10; standard error was asymmetrical for CN (upper (U) and lower (L) values are shown);

^b For Experiment 2, values are estimated marginal means adjusted for a covariate of mouse body mass = 33.30 g;

^c Data not measured for Experiment 1.
