Effects of individual housing on behavior and resistance to Ehrlich tumor growth in mice
This study analyzed in Balb/C mice the effects of individual housing on behavior, serum corticosterone and resistance to Ehrlich tumor growth. Mice (60 days old) were individually (IH) or grouped housed (G) (10–12 animals/cage) for 14–21 days. The 1st day of the housing condition was considered experimental day 1 (ED1). Results showed that on ED21, […]
Acute social stress-induced immunomodulation in pigs high and low responders to ACTH

These stressors are thought to impair immune defences and might contribute, at least partly, to the prophylactic use of antibiotics. Robustness was recently defined as the ability of an individual […]
