2 1 6 ORGANISMS RESEMBLING BACILL US TUBERCULOSIS. 



Infection of the child may occur during its intra-uterine 

 life. If the mother is infected while she is enceinte, the child 

 is also infected, except when infection occurs during the last 

 two months of pregnancy, during which time the infection 

 of the child is not so apt to occur. The mother is infected 

 through sexual intercourse, and the disease is carried to the 

 foetus through the placenta. It is less probable that the fcetus 

 is infected first, and that the mother is infected through the 

 foetus. When the child is suffering from an intra-uterine 

 infection the primary lesion is invariably absent at birth. If 

 the primary lesion makes its appearance after the birth of the 

 child, the infection has undoubtedly occurred extra-uterine.
