ANOMALIES AND DISEASES OF YOUNG PIGS 227 



tion extensive. Tliere is a tendency for this infection to permeate 

 subsurface structures and become diffuse. It appears from the cases 

 observed that B. pyocyaneus has a tendency to invade the tissues of 

 the snout and nasal chambers and is prone to produce the condition 

 described elsewhere as "bull-nose." The pus in lesions resulting 

 from B. pyocyaneus is green or greenish yellow in color. 



Lesions produced by B. necrophorous are described on page 319 

 under the head of necrotic stomatitis. 



The B. coli communis may produce suppurative or non-suppura- 

 tive inflammatory lesions. These lesions are usually circumscribed 

 and the pus is of a dirty white color. 



Symptoms. — This condition occurs in the first few days after far- 

 rowing. Rather extensive lesions have been observed in one-day old 

 pigs, indicating infection at the time of or immediately after far- 

 rowing.. It occurs in pigs up to three weeks of age but is not com- 

 mon in pigs after they are ten days old. Affected pigs are listless; 

 they have a tendency to remain quiet and are not active and playful 

 as is the healthy pig. In a few hours or within a day or two there 

 is marked depression and there may be diarrhea. If an affected pig 

 is caught and carefully examined lesions will be found that are 

 responsible for the condition. Only one pig in a litter may be affected 

 but it is not unusual to find one-half or even the entire litter affected. 



Treatmetit.^Bj proper care and treatment it is possible to prevent 

 losses of pigs from stomatitis. Every pig should be carefully in- 

 spected at least once daily until ten days old by the attendant to 

 ascertain their exact condition and incidentally to note any disturb- 

 ance that may be overcome readily. All infected and especially 

 necrotic tissue should be removed by a curette and the wound thor- 

 oughly saturated with tincture of iodin. One or two such treatments 

 usually is sufficient and the large percentage that recover will prob- 

 ably be surprising to those who have not attempted to relieve these 

 cases. Clean quarters should be provided and each sow and her 

 litter should be kept separate to prevent spread of the infection.
