Due to the high prevalence and great economic impact of depression, studies with animal models have been increasingly used to identify neurobiological mechanisms associated with this disorder. However, many animal models use stressful conditions that are not consistent with what we observe in the modern human world. Examples are the chronic unpredictable stress and the electric shock model used in rodents. It's well established the social stress as the major cause of depressive disorder in human, in this way a social defeat stress model was recently standardized and can induce depressive-like behavior of social avoidance, a typical human depressive behavior. In this model, mice are exposed on consecutive days to an aggressor mouse, suffering brief periods of physical aggression followed by longer periods of visual and olfactory (sensory) contact and, as a consequence, a relationship of social submission is characterized. Thus, the objective of this work is to describe a social defeat stress protocol using swiss mice as resident, also describing valuable procedural suggestions that will help researchers to reproduce the model easily
