DOIAbstract
Parasites may induce metabolic changes and imbalances in the redox status of hosts. This study tested the effect of parasites on the O2 consumption rate (O2-CR) of hosts, and explored the link between O2-CR and oxidative stress in parasitized hosts. We used the symbiotic pea crab Calyptraeotheres garthi and its slipper limpet host Crepidula cachimilla as models. The O2-CR of long-term (3 months) infested limpets was 2.5 times greater than that of long-term uninfested limpets. Also, the O2-CR of limpets stripped of crabs 24 h before measurements was intermediate between that of long-term infested and uninfested limpets. These results indicate a parasitic relationship between C. garthi and Cr. cachimilla, and suggest that the effect of the pa...
