Coccidian Enteritis in the Dog. 265 



Diagnosis can always be made by microscopic examination of 

 the fresh warm faeces. 



Prevention. This will consist in the avoidance of water and of 

 green food from soils where the disease has been found to prevail. 



Treatment. Antiseptics given by the mouth have proved of 

 very little avail having as a rule lost their power through dilution 

 in the contents of the stomachs. They may still be given to 

 keep in check the propagation of the coccidia in the fourth 

 stomach. Silver nitrate, iron sulphate, lead acetate, tannic acid, 

 oak bark, carbolic acid, cresol, lysol, salicylic acid, hydrochloric 

 acid, sulphuric acid, hyposulphite of soda have been used in this 

 way. The same agents may be used with better effect as enemata 

 being forced as far as is consistent with safety and frequently re- 

 peated. Quinia and iodide of potassium may also be given as par- 

 asiticides. Mucilaginous gruels and decoctions should be given 

 at first, followed by mashes as they can be borne, but the food 

 must be moderate and easily digestible until full convalescence 

 has taken place. 



The flesh of animals killed while suffering from this affection 

 has been eaten by man with impunity. 



COCCIDIAN ENTERITIS IN THE DOG. INTESTINAL 

 COCCIDIOSIS. 



Causes. Two parasites have been found in connection with this 

 disease in the dog ; the Coccidium perforans, already described, 

 and the Coccidium bigeminum. 



Coccidium Bigeminum, var. Canis. This is elliptical and 

 from 12 to 15/u. long by 7 to 10/1 broad. They are usually found 

 in pairs lying side by side, and sometimes both in the same en- 

 velope indicating multiplication by division along the longitudinal 



axis. 



The bigeminum is held to be harmless, but the perforans, as in 

 the cow and the rabbit is very injurious and even fatal. The symp- 

 toms are those of digestive disturbance, dullness, loss of appetite, 

 retching, vomiting, colic and foetid and bloody diarrhoea. Irrita-
