One of the tasks of genetic improvement is to select animals resistant to infectious diseases, especially those difficult and expensive to eradicate, in order to obtain healthy animals in which endogenous potentiality is optimised and therapeutic events reduced. Out of these kind of infections are those caused by intracellular bacteria like Brucella, Mycobacteria and Salmonella which hold extreme importance both for the incidence and for the effects on human and animal health. In Italy, despite eradication programs, bovine Tuberculosis is still a sanitary and economic problem and the possibility to find a gene for susceptibility or resistance to the disease to be used for selection is quite promising.
