THE FUNCTION OF THE SPLEEN IN THE EXPERIMENTAL INFECTION OF ALBINO MICE WITH BACILLUS TUBERCULOSIS : SECOND PAPER.
The resistance to an infection with the tubercle bacillus which can be given to mice by the removal of the spleen is lost when fresh spleen, either of mouse or sheep, is added to the diet. The logical conclusion that splenic function in its relation to the specific infection is restored by feeding spleen cannot, however, be drawn; because, in the first place, the character of the disease in the splenectomized spleen-fed animals differs somewhat from that in intact animals; and, secondly, because fresh spleen when fed to splenectomized animals apparently gives rise to an acute intoxication. This intoxication occurs quite regularly in mice. It is manifested in the infected animals and in those not inoculated. It has been seen in one of two splenectomized dogs experimented upon. Up to the present it can hardly be definitely characterized, but it seems to be best marked out by the specific anorexia associated with it.
