 body. Sopticaeuiia indicates a j^eiicral infection, aii<l may ifsiilt in the 

 ciilar;;cnicnt, on.sior.L'cnicnt or tlic loiiiiatidn of necrotic centers in the 

 liver, liiuneys. lynipluitic j^hinds, etc. Tyi'iniii is characterized by the 

 formation of abscesses in different parts of the body. Both of those con- 

 ditions may exist at the same time. 



Causes. — These are tlie pus-itroduciiif,' iiiicroltes, especially staphylococ- 

 cus pyogenes aureus or albus and streptctcnccus pyogenes, that enter the 

 tissues through bruises or abrasions that permit the germs to become 

 lodged beneath the skin, or through extensive wounds. Sometimes they 

 remain at the point of infection, l)ut may be transferred from here by the 

 blood stream at different points, forming supurating centers or infect 

 the tissues generally and become widely distributed. This condition is 

 not rare as a result of puti-if active changes in the uterus following an in- 

 flammation of the organ, or as a result of retention of the foetus. 



Symptoms.— Unless the symptoms follow an extensive infection, re- 

 sulting from a dithcult birth, an operation or a large wound, the owner 

 does not connect them with a disease of this nature. At the point of 

 infection an abscess may form or the part become greatly swollen and 

 oedematous. The body temperature is elevated, and in serious cases the 

 appetite becomes impaired. Muscular tremors may be noticed, and the 

 hog becomes dull and stupid. It is generally seen hiding in the weeds or 

 litter or in some cool, quiet place. Sometimes the animal has a diarrhoea. 

 In serious cases it becomes greatly emaciated and death may occur in 

 a few days. Recovery frequently occurs, and in time the hog begins to 

 thrive. 



Treatment.— The treatment is mostly preventive, and consists in proper 

 care being given most wounds, especially if extensive, and in using anti- 

 septic precautions in all operations on the pig. Abscesses should be 

 opened promptly. The opening should be made at the lowest joint, so that 

 all the pus can drain out. The after treatment consists in washing the 

 cavity with an antiseptic wash for a few days. The opening should be 

 made large and not permitted to close iintil the cavity has entirely filled 

 in. In large wounds we should try and bring about the formation of a 

 healthy granulation surface as soon as possible. ^If necrotic or dead tis- 

 sues form in a wound it must be removed and a healthy surface pro- 

 moted by the use of antiseptic dressings. In cases of local septicaemia 

 this is all the treatment necessary. When the disease is generalized, the 

 treatment is usually hopeless. Alcohol, salicylate of soda and quinine 

 are the drugs usually given in" these cases. Plenty of clean water should 

 be allowed. The animal should be coaxed to eat easily digested and highly 

 nutritious food in order to prevent its becoming weak. 



Infectious Arthritis. Causes.— This disease occurs in pigs a few days 

 old and is caused by septic germs that enter the system by way of the 

 navel or umbilicus. Ulth arid dirty pens are among the predisposing
