TWELFTH BIENjNTIAL REPORT. 31 Of the distinct diseases affectins? the cow, which also affect man and which may be communicated from one to the other, tuberculosis is of tirst importance. When Koch discovered the bacillus of tuberculosis and proclaimed the identity of bovine and human tuberculosis, there was little hesitancy in accepting a conclusion so closely in harmony with the experience and observation of scientific workers in l^oth human and veterinary medicine. Later investigators called attention to the difficulty in transmitting human tuberculosis to bovines, and still later the fact was pointed out that the bacilli from bovine and human sources often possessed morphological and cultural peculiarities sufficient to differentiate them; but when Koch followed^ in 1901^ with the remarkable declaration that bovine and human tuberculosis were different and not interconununicable, few scientific investigators were willing to accept the ijlctnm on the insufficient evidence produced, and at once investigations were started all over the civilized world to determine the truth or falsity of Koch's declaration. In the meantime progress towards preventing the communication of bovine tuberculosis to man received a decided setback. The results of the investigations, stimulated by Koch's dogma, indicate, as clearly as the nature of the case will permit, that bovine tuberculosis may be and is communicated to man. It has been shown that the bacillus from human tuberculosis is capable of producing tuberculosis in many animals, but for no animal, unless man is the sole exception, is it so virulent as the bovine germ. If the bovine bacillus is more virulent for all other animals, including monkeys and apes, it very logically follows that it probably is also more virulent for man than the human bacillus. Of course, Koch has not recanted. He still maintains the position taken in 1901, but the fact is now pretty generally recognized that bovine tuberculosis may be a source of danger to man. The next question to arise was, naturally, To what extent is bovine tuberculosis a source of infection to man? In their efforts to show that bovine tuberculosis was rarely communicated to man^ the fact of the greater frequency of pulmonary than abdominal tuberculosis was pointed out, and the claim that intestinal tuberculosis of children, the greatest consumers of milk, was rare, were made much of. Recently much evidence has been developed showing that intestinal or al)dominal tuberculosis of children is not so rare as claimed by those who maintain that bovine and human tuberculosis are not interconununicable. And still further to the dismay of those who cling to old beliefs because they are old, even the time-honored assumption that the chief mode of entrance of the infection agent is through the inhalation of germ-laden dust particles has l)een challenged and met with an arraj'
