Effect of antibiotics on energy expenditure in Ob/Ob and C57BL/6J (WT) mice
Summary Data Summary
Investigator Knotts, Trina
Description Deletion of leptin in the Ob/Ob mouse (B6.Cg-Lep/J) produces a deleterious
metabolic phenotype. Mice are obese with many of the deleterious effects of
obesity (hyperphagia, transient hyperglycemia, glucose intolerance, elevated
plasma insulin, hypometabolic, and hypothermic) independent of a high fat,
high-energy diet.

Energy expenditure will be assessed by indirect calorimetry in C57BL6/J (WT) and
Ob/Ob mice treated with antibiotics (water, 1g/L Neomycin+ 0.5g/L Vancomycin, or
0.5g/L Cefoperazone) in drinking water.
