Immunological investigations regarding the cuantification of cellular populations of the new born calves

Abstract

The scientific investigations reflected in this study have the purpose of quantification of the cellular populations at the new-born calves in different periods of age. There were determined in dynamics the number of the lymphocytes indices, T and B cells with populations. These data indicates the principal effector role in the immune system activity, as effector of the immune reactions mediated cellularly and humorally, capable to sinthesize some lymphokynes etc. There were determined the increasing of the concentration level of the T and B lymphocytes with populations, which justifies the early instalation of the cellular and humoral specific resistance of the immune status and receiving the antibodies through colostrum in the neonatal period, as result of the instalation of the colostral immunity. The research results demonstrated, that the new-born calves are born with well organized cellular lypmhocytic immune system, represented by the corection of the immune homeostasis of the organism.
