172 VETERINARY STATE BOARD 



Give mode of examining a horse for soundness and a certificate for 

 same. 

 Examine the horse in the stable, outside and at work. Record a 

 description of the animal for the purpose of identification. Exam- 

 ine thoroughly every accessible part or organ by inspection, palpa- 

 tion and auscultation. As very few horses are absolutely sound, 

 most examiners employ the phrase "serviceably sound," meaning 

 that the defects present will not interfere with the animal perform- 

 ing the required duty.

 Mr. John Doe, a bay gelding, 15.2 hands high, 9 years old, white

 mia, cribbing without evidence on teeth, etc. 



Acute General Infectious Diseases 



What are the essential causes of hog cholera and swine plague?

 caused by an ultramicroscopic, filtrable virus. Besides the virus, 

 two species of bacteria, the baeiUus suipestifer and the bacillus 

 suisepticus, play an important part in the etiology of hog cholera. 

 The secondary affections of the intestines, lymph-glands and lungs 

 are usually produced by the pathogenic action of these bacteria. 



Swine plague is caused by the bacillus suisepticus. 



Give the diagnostic symptoms of hog cholera and swine plague. 



Hog cholera: Acute form, fever, variable appetite, vomiting, 

 conjunctivitis, constipation followed by diarrhoBa which may be
