SECONDARY IMMUNODEFICIENCY IN PATHOGENESI S OF PROTRACTED INTESTINAL INFECTIONS AND POTENTIALITIES OF RELEVANT IMMUNOCORRECTION

Acute intestinal infections (AII) are characterized by marked defects of immune homeostasis. These were not related to the disease etiology though depended on the infection severity and manifested with T-lympho penia, reduced count of circulating T-helper cells in normal amount of T-supressor cells. This resulted in low immunoregulatory index (CD-4/ CD-8). Immunological criteria have been determined indicative of the t endency to formation of a protracted AII course and long-term persiste nce of the agent in the host.
