Ulcerative Dermatitis Syndrome Usually in black mice of a C57BL/6 background. Mice will develop a dermatitis with alopecia and skin ulcers. Mice will scratch at the effected region until ulcers form. The ulcerated areas often scar, causing restriction of limb movement. Any skin lesions should be brought to the attention of vet services.
Dystocia = difficult birth This is when a female has difficulty giving birth. Signs might include vaginal discharge, dehydration, and lethargy. Normal mice give birth only at night – if they are in labor during day, something is wrong. There may also be dead pups in the cage. Normal birth times = 1 – 3.5 hours for a litter of 11 pups
