title: [Consequences of bacterial product interaction with the immune system in newborn mice].
abstract: The immunological competence of a newborn mice group, inoculated with a heat killed suspension of staphylococci, was studied to find out if the treated mice preserved the immunological competence of the T lymphocytes, for induce an allograft. A group of CD1 newborn male mice were injected intraperitoneally with the bacterial suspension, every three days during a four weeks period. Other group received only isotonic saline solution. The lymphocyte ability to form hemolytic plaques and their capacity to provoke a local graft-versus-host reaction in F1 receptor animals was studied in both groups. The results showed that the staphylococci treated newborn mice had a decreased capacity to form anti-erythrocyte antibodies without modification in their reactivity against histoincompatible antigens. Newborn mice, runting-like disease; bacterial inoculation; immunological response in.
