What domestic animals are liable to be attacked by the hookworm 



(uncinaria, anchylostoma) ? How do such worms enter 



the body and what symptoms do they produce? Give 



treatment. 



Ox, sheep, cat and more commonly the dog. The worms enter 



the intestinal tract through the drinking water which contains the 



larvae. 



Symptoms: Digestive derangements, dulness and indifference-, 

 whining, tympanites, diarrhoea, loss of appetite, nervous disorders, 

 nausea, aneemia and emaciation. 



Treatment: Thymol, 2 to 15 grain doses. Separate the sick 

 from the well to prevent reinfection. Thoroughly clean and disin- 

 fect kennels. Supply pure drinking water. 



What are coccidia? Name the domestic animals infested by coccidia, 

 mentioning in each case the organs infested. Give diag- 

 nosis, prevention and treatment in each case. 



Coccidia are a genera of sporozoa, single-celled microorganisms 

 provided with a protoplasmic-celled body in which is found a 

 nucleus. 



Cattle, sheep, rabbits, fowls and, occasionally, dogs and pigs 

 are infested. The intestines are more commonly affected in cattle, 

 sheep and fowls, whereas the liver is usually the seat of disease in 

 rabbits, dogs and pigs. Both organs may be affected in all animals. 

 There are a few cases of diseases of the air passages reported in 

 cattle, dogs and rabbits, due to coccidia. 



Diagnosis : Fetid, hemorrhagic diarrhoea, fever, loss of appetite, 

 weakness, death, jaundice, when liver is affected; coccidia may be 

 found in the faeces by microscopic examination. 



Prevention : Provide pure water ; disinfect faeces with 3 per cent, 

 watery solution of sulphuric acid ; destroy carcasses and thoroughly 

 disinfect. 



Treatment : Remove from pastures ; give dry foods and intestinal 

 astringents and antiseptics. Useless to treat the hepatic form.
