Abstract
Introduction There are few reports of in vivo muscle strength measurements in animal models of ICU-acquired weakness (ICU-AW). In this study we investigated whether the Escherichia coli (E. coli) septic peritonitis mouse model may serve as an ICU-AW model using in vivo strength measurements and myosin-actin assays, and whether development of ICU-AW is age-dependent in this model. Methods Young and old mice were injected intraperitoneally with E. coli and treated with ceftriaxone. Forelimb grip strength was measured at multiple time points, and myosin-actin ratio in muscle was determined. Results E. coli administration was not associated with grip strength decrease, neither in young nor in old mice. In old mice, the myosin-actin ratio was lower in E. coli mice at t=48 and higher at t=72 hours compared to controls. Conclusion This E. coli septic peritonitis mouse model did not induce decreased grip strength. In its current form, it seems unsuitable as a model for ICU-AW. This article is protected by copyright.

An easy way to objectively quantify the muscular strength of mice and rats, and to assess the effect of drugs, toxins, muscular (i.e. myopathy) and neurodegenerative diseases on muscular degeneration. It is widely used in conjunction with the ROTAROD motor coordination test: a normally coordinated rodent will show a decreased latency to fall off the rotating rod if its muscular strength is low. The Grip Strength Test is a must for your research on activity, motor control & coordination, and is particularly well suited for studies on Parkinson's & Huntington's disease.
