S 188. Characterization. Tetanus is an infectious dis- 

 ease (toxemia) is which the specific organisms are locahzed at 

 the place of inoculation. It is characterized by spasmodic con- 

 traction of the muscles referable to the nervous system and 

 by the absence of obvious tissue changes. It is the result of a 

 specific wound infection. All mammalia including man are 

 susceptible. It occurs most frequently in horses, asses and 

 mules ; next to them in the smaller ruminants such as the 

 sheep and goat ; it appears least often in the dog. It is re- 

 ported to occur rarely in birds and fowls are supposed to be 

 immune. The human species is very susceptible.
