Water: Adjusted with hydrochloric acid to pH 2.8-3.1 and supplemented with menadione sodium bisulfite (final concentration 0.4 milligram/milliliter) to compensate for potential decrease in vitamin K activity upon autoclaving; water supplied in pinhole type bottles (Thoren Caging Systems, Inc. Hazelton, PA). Housing: Thoren cages; Thoren Maxi Miser #3 cages used for some strains as part of a PIV (pressurized individually ventilated) system. Bedding: Steam autoclaved white pine shavings.

Same-sex mice were grouped 10 per cage until one week prior to testing when they were housed in groups of 5. Testing was conducted at 60 days of age at approximately the same time of day on groups of 40 mice. Five mice per sex per strain were tested over a 4-day period until 20 males and 20 females of each strain were tested.
