TETANUS OR "LOCKJAW" 



Tetanus or "lockjaw" is a very common disease i'n' Cuba and 

 causes serious losses of horses and mules. It also claims many 

 human victims as well. Formerly the infant mortality from 

 tetanus due to umbilical infection was very great, but owing to 

 the efficient work of the National Sanitary Deparment in 

 diffusing information as to the cause of the disease and sup- 

 plying antiseptic dressi'ngs, the mortality has been reduced to a 

 mínimum. 



Aside from human beings, tetanus generally occurs in horses 

 mules and asses, occasionally in sheep and goats and so rarely 

 in other domestic animáis as to be of relatively no importance. 



Tetanus is more common in tropical and semi-tropical coun- 

 tries than in colder regions. This is probably because the tem- 

 perature and moisture eonditions are more favorable for the germ 

 that causes the disease. 



CAUSE 



Tetanus or "Lockjaw" is caused by a microscopio germ (Ba- 

 cilus of Nicolair) that gains entrance to the body of an anim.ü, 

 usually through a wound, where it developes and produces a
