Figure 3. Hsp70 expression in zebra mussels infected or not by microparasites.

Hsp 70 expression (Surface density, Sv) in each experimental group of the microparasite study. Both host sex and parasite species (Ophryoglena spp., Oph; Rickettsiales-like organisms, RLOs; co-infections, Oph-RLO) were taken into account. The center line shows the median, 25^th-75^th percentile (within box), minimum/maximum value (error bar). The small circles represent atypical values and the stars the extreme values.
