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.

Une méthode simple pour quantifier objectivement la force musculaire des rats et souris et l'effet de drogues, toxines, maladies musculaires (ex: myopathie) et neurodégénératives. Cette mesure de force est souvent employée en association avec le test de coordination motrice ROTAROD: un sujet présentant une coordination normale montrera des résultats médiocres en cas de faible force musculaire. Un must pour vos recherches sur l'activité, la coordination et le contrôle musculaire: particulièrement utile pour vos études sur les maladies de Parkinson et Huntington.
