26 SWINE DISEASES 



This disease usually runs a rapid course, as a rule 

 terminating within five to eight days. 



The prognosis should be guarded. 



Treatment. The treatment consists in giving 

 demulcent drinks after having removed the cause. The 

 content of the bowels should be kept soft by laxatives. 

 The affected animals should be separated from the 

 healthy and given good quarters. 



Phlegmonous Gastritis 



Phlegmonous gastritis occasionally occurs in bogs 

 and is usually the result of infectitfn with streptococcic 

 micro organisms. 



Lesions. The anatomical changes occurring in 

 phlegmonous gastritis consist of an intense tumefaction 

 of the mucosa due to accumulation of pus or other 

 inflammatory products in the submucosa. Patches of 

 the mucosa may become necrotic and desquamate. In 

 other instances large sinuous tracts are formed beneath 

 the mucosa and in these pus accumulates in large quan- 

 tities. The muscular layers of the stomach frequently 

 become infiltrated with pus; the inflammatory process 

 may extend to and involve the serous coat. 



Symptoms. The evidences of phlegmonous gas- 

 tritis are not distinct and separable from those of croupous 

 gastritis. There is usually intense pain, indicated by the 

 constant change in position of the animals. Vomition is 

 usually frequent, the vomited material being small in 

 quantity and largely mucous or mucopurulent in char- 

 acter, and it is not infrequently mixed with blood. There 

 is inappetence, thirst, and a drawn-up appearance of 

 the abdomen, with arching of the back. The temperature 

 ranges from 104 to 107 degrees Fahrenheit. Constipa- 

 tion is usually quite marked in the beginning, but may be 

 succeeded by diarrhea. 



The course of this disease varies from three to seven 

 days. The prognosis should be guarded, as the disease 

 is usually fatal.
