necrophorus. This infection in cattle results in what is termed 

 "ulcerative-ano-vulvitis," a local infection. In sheep it results in 

 what is commonly called "lip and leg" ulceration. In swine this 

 condition procruces "sniffles" or "bull nose," necrotic-pneumonia 

 and necro-entiritis. This infection is rather rare in cattle and 

 sheep but is quite prevalent in hogs and in a}l external forms 

 responds rapidly to treatment. The internal necrotic conditions 

 found in hogs are more difficult to overcome and cause consider- 

 able loss. 



RABIES. 



Rabies is practically extinct in Iowa at the present time and 

 when prevalent should always be controlled by strict quarantine 

 measures and the destruction of infected animals. There should 

 be perfect isolation of all exposed animals including confinement 

 or destruction of dogs in the community where the outbreak 

 occurs. 



Sheep scabies is more or less prevalent at all times and is 

 apparently on the increase, in Iowa, in the last two years. 



We find that many shipments of feeder sheep imported into 

 the state and passed through the most approved dips develop 

 more or less disease during the feeding period. The native sheep 

 in some localities are infected. 



In order to properly control this infection in sheep this depart- 

 ment should have one or more specialists devoting their entire 

 time to the treatment of flocks and disinfection of premises. 



STOMATITIS. 



Stomatitis is a diseased condition occasionally found in cattle 

 and more rarely in horses. It is of special interest when found in 

 cattle because of its similarity to European foot and mouth dis- 

 ease, which fact makes it necessary to investigate reports very 

 promptly and thoroughly. Such investigation is always made 

 when reports are received stating that cattle are affected with sore 

 mouth and, when there is the least doubt as to the nature of the 

 infection, experimental inoculations are promptly made. 



TUBERCULOSIS. 



Tuberculosis is not only the greatest menace known to human 

 life, but undoubtedly is the cause of a greater economic loss in 

 cattle and hogs than all other diseases combined. This statement
