What animals and what organs are infested by linguatula taenoides? 

 Give diagnosis and treatment, both therapeutic and pre- 

 ventive. 



This parasite infests the nasal chambers, turbinated bones, fron- 

 tal sinuses and pharynx of the dog and occasionally the horse. 



The diagnosis is based upon sneezing, coughing, rubbing nose, 

 dyspncEa, epistaxis, convulsions and finding the parasite in the 

 discharge. 



Treatment : Nasal douche of benzene 5 parts, and olive oil 100 

 parts. Prevent dogs from eating the raw offal of sheep. Destroy 

 the heads and carcasses of dead sheep containing the larvae. 



How does vomiting in cattle differ from regurgitation? Where does 

 the ejected food come from? How is vomiting diagnosed 

 and treated? 



In vomition, there is a greater effort made and the quantity 

 is so great that it runs from the mouth, whereas, in regurgitation, no 

 effort is required and the amount is so small that it is retained in 

 the mouth. The ejected material comes from the rumen. Vomit- 

 ing is diagnosed by the uneasiness, straining and peculiar smell of 

 the ejected material. Treatment is seldom called for as the act 

 relieves the patient and removes the cause. If too prolonged, give 

 sedatives, such as bromides and chloral and empty the bowels 

 with liberal doses of Epsom salts. 



What parasites affect the gullet of cattle? State other habitats of any 

 of these parasites. 

 Spiroptera scutata and the larvae of the oestrus (hypoderma) 

 bovis are also found in the stomach of cattle and the gullet of the 

 horse. Psorospermia oviforme (coccidia) inhabit the mucous mem- 

 brane of the gullet and various other organs, including the liver, 

 intestines, etc., of sheep, goats, pigs, rabbits and man. Sarcosporidia 

 invade the muscles of the ox, pig, sheep and horse. 



Describe the symptoms of a case that on post-mortem examination 

 reveals a ruptured stomach. 



The abdomen enormously distended with gas on the left side 

 under the ribs. Colicky pains, dyspnoea, belching of gas, retching 

 and regurgitation of stomach contents. Sudden paleness of mucous 

 membranes, syncope and death. 



Give causes, symptoms and treatment of tympanites in cattle. 



Also called "hoove," "hoven," and bloating. 

 Caused by gaseous fermentation of the contents of the rumen. 

 Overfeeding on green foods, especially clover when wet with dew.
