THE DISEASES OF CATTLE, 



CONTAGIOUS PLEUROPNEUMONIA, 



Also called lung disease, pulmonary murrain, zymotic 

 or epizootic pleuro-pneumonia, &c, is an incurable febrile 

 disease. Gresswell says it is believed to be generated by 

 and due to a definite micrococcus (mite). It may be acute, 

 subacute, or chronic. 



Symptoms. — Elevation of temperature or a slight cough 

 is usually the first sign. The temperature will range from 

 100 to 107°. Shiverings; hair stands wrong way; slight 

 loss of appetite ; breathing difficult and laborious ; nos- 

 trils dilated ; flanks heave ; mouth hot ; muzzle dry ; gums 

 pale, lilac color; walls of chest, rib spaces, and back from 

 withers to loins more or less sensitive to pressure ; appe- 

 tite worse; milk diminishes; emaciation begins; bowels 

 irregular; watery or sticky discharge from nostrils; ab- 

 normal sounds in bronchial tubes and mucous rattle over 

 lungs ; cough worse ; back arched and head and neck ex- 

 tended when coughing. 



In what is called the second stage, these symptoms are 

 intensified and others appear: Death sometimes occurs in 

 the first stage. 



Remedy. — Slaughter and general and thorough disin- 

 fection of premises. Vaccination and inoculation should 

 be left to the veterinarian.
