408 SEPTIC BLOOD DISEASES. 



exudate is found on the pleural surfaces, whilst in others they 

 have simply presented a more or less deeply congested appear- 

 ance. On cutting into the lung structure, minute yellowish- 

 white spots are to be seen, and if the lung be pressed, a muco- 

 purulent discharge will be seen to issue from the inflamed 

 bronchi, and if this discharge be examined microscopically it 

 will be seen to contain the microbes more or less abundantly. 



The pericardium, heart, liver, kidneys, and digestive tract 

 will also often be found more or less inflamed. 



Treatment. — Assuming that the usually harmless microbe 

 becomes virulent under abnormal conditions of the body of its 

 host, and in order to limit the spread of the disease, separation 

 of the sick from the healthy should at once be resorted to, and 

 the surroundings cleansed and disinfected. Medicinally but little 

 can be done beyond endeavouring to destroy the virulence of 

 the microbe by the administration of carbolic acid, hyposulphite 

 of soda, or remedies having a similar efl'ect, as the condition of 

 the animal might justify.
