[Reaction of rat embryo tissues to mechanical trauma and to infection with Staphylococcus aureus (strain 209)].
Experiments were conducted on albino rat embryos. A study was made of healing of the skin wounds and the reaction of the tissues to the intrauterine injection of pathogenic Staphylococcus aureus (strain 209). In horizontal cut the orthotonic position of the fetus and retraction of the skeletal muscles prevented wound contraction and epithelialization of its surface. In vertical cut the margins of the wound were approximated and healing took place without formation of granulation tissue by epithelialization of the wound surface 2 days after the operations with regeneration of the squamous epithelium. To the action of the pathogenic staphylococcus the embryos responded by a local untypical reaction with the prevalence of alterative changes and the accumulation of the histiocyte-like cells near some colonies. There was no exudative inflammatory reaction either during the trauma or in injection of a staphylococcus culture at all the periods of the intrauterine life.
