of both the human and bovine types, although they may develop minimal local
changes at the seat of inoculation when mammalian tubercle bacilli are employed.
As the three fowls used in this experiment could not be infected, the possibility of
the goat strain of tubercle bacilli being of the avian type is excluded. On the other
hand, it has been stated that guineapigs are highly susceptible to infection with
both the human and bovine types of tubercle bacilli, but that rabbits are more
susceptible to the latter than to the former form of infection. The strain of
tubercle bacilli isolated in the present experiments proved to bo particularly
virulent for rabbits, as evidenced by the occurrence of extensive miliary lesions in
the lungs of these animals [Plate II, fig. 2]. This would appear to point to the
conclusion that the strain was of the bovine type.
