Immunotherapy Efficacy of Mycobacteria Cell Wall Preparation (Immunoboost K™) in New Born Calves Artificialy Infected with Enterotoxigenic Escherichia Coli

Abstract

Although physiologically developed, the immune system of a new born calf is often unable to cope with the wide array of microbial challenges to which it is exposed in the early stages of life. This vulnerability is primarily due to the prolonged lag phase before antibody syntheses. Passive immunity, in the form of colostral immunoglobulins is the natural defense mechanism to cope with those pathogens. However, colostrum does not always provide protection against a wide spectrum of pathogens. Primarly, this is due to the absence of specific antibodies or a low concentration of passively transported antibodies. It is obvious that new born calves required temporary help until they develop their own specific immune response.
