UDDER-STAPHYLOMYCOSIS 61 



Amputation of the teat before gangrene has set in is 

 not to be recommended, since saprophytic invasion is thus 

 made easier and this dangerous complication encouraged. 



In abscess formation one may shorten the course of 

 the affection by incising the abscesses which are accessible 

 for the operation. 



STROMA-iNFECTioN ^Interstitial Mastitis] 



The stroma-infection only occurs as a wound-infection 

 and is therefore a complication of an udder wound. 



It is a comparatively harmless condition as long as it 

 does not become complicated with a milk-infection. 



Septic-intoxication does not take place so readily be- 

 cause of the lack of nutrient media for the bacteria. 



It progresses to localized wound necrosis with suppura- 

 tion. Secondary infection with streptomycosis and coliba- 

 cillosis is not unconmion, and gangrene may also develop. 



This wound-infection is treated following the common 

 surgical methods.
