The effects of handling on antibody production, mitogen responses, spleen number, and lymphocyte subpopulations

The immune response was depressed when mice were picked up by the tail and held gently in the palm without restraint. From the methodological point of view, handling of experimental animals may be a significant uncontrolled factor in many in...

Varied cages result in more aggression in male CFLP mice

Male CFLP mice were quicker to show signs of aggression in both large wooden cages and standard plastic holding cages to which objects such as bricks and extra sources of food and water had been added. .. Attempts to provide...

Urine marking in populations of wild house mice, Mus domesticus rutti, I. Communications between males.

Various hypotheses proposed for the function of urine marking in communication between male house mice were examined by comparing the predicted responses towards urine marks with those observed within eight captive territorial family groups. The responses of individual resident males...

Effect of in-house transport on murine plasma corticosterone concentration and blood lymphocyte population

A significant increase in plasma corticosterone concentration was seen in mice immediately after [in-house] transport. The normal circadian rhythm of plasma corticosterone concentration was altered for the subsequent 24-hour period. .. The .. acute increase in plasma corticosterone concentration was...
