POST-MORTEM REPORT 153 



The right anterior quarter of the udder was moderately 

 swollen and hard. Both posterior quarters were slightly 

 swollen and firm in their inferior parts. 



Right anterior quarter: The incision was smeared by 

 a yellowish-green, thick pus. The cut surface was even, 

 grayish-white, and firm. The lobuli showed no milk points, 

 but yellow pus points instead. Here and there a number 

 of yellowish-green pus foci the size of a hemp seed were 

 present which were surrounded by a thick, white fibrous 

 capsule, the inside of which showed a green pigmentation. 

 These foci gave off a disagreeable putrefactive odor. A 

 few of these pus foci were cylindrical, extended and formed 

 fistula. Gray spongy fibrin was present in the milk-ducts 

 and cisterns. 



Both posterior quarters presented similar but somewhat 

 less widely distributed lesions. Other parts of the udder 

 showed no alterations. 



In the fibrin and yellowish-green pus a large number 

 of small, thin Gram positive bacilli (pyogenes bacilli), as 

 well as other bacteria, were observed (cocci, Gram negative 

 rods, putrefactive bacteria).
