Experimental infection with Salmonella enterica subsp. diarizonae serotype 61:k:1,5,(7) in sheep: Study of cell mediated immune response

These results demonstrate that after experimental infection of healthy lambs with S. enterica subsp. diarizonae serotype 61:k:1,5,(7) infection was maintained for at least one year in the upper respiratory tract and that digestive route should be taken into account as a possible way of SED elimination. Moreover, SED infection caused a weak response of the T cells; nevertheless, more studies are needed to understand the mechanisms involved in the immunitary response and pathology of CPR in sheep associated with Salmonella enterica subsp. diarizonae infection.
