Fight wounds

Fight wounds

Etiology:   Mice (particularly males) may fight and can inflict severe wounds upon each other.  Breeding females may also fight.  DBA/2, BALB/c, SJL and C57BL/6 mice are often aggressive [2].

Incidence:  Common, especially among male mice.

Clinical signs:  Wounds are usually are located on the face, back, and genital areas.  If tail biting occurs, the tail may become gangrenous and slough.  The wounds may become infected and develop into abscesses.

Pathology:  Multifocal cutaneous excoriations are observed grossly.

Diagnosis: A characteristic pattern of open and healing wounds along dorsal surfaces of the trunk is diagnostic [3].
