INFECTIOUS DISEASES 301 



Furious rabies is more coiiinion in the horse. The animal 

 is very nervous, restless and alert. It may attack other animals 

 in a vicious manner, kicking and biting them. The animal 

 does not seem to care to eat or drink, and usually shows violent 

 nervous symptoms, such as biting the manger, rearing and kicking 

 when confined in the stable. 



Cattle butt with the horns and show a tendency to lick 

 other animals. They bellow more than common and the sexual 

 desire is increased. Parahi;ic symptoms are manifested early 

 in the disease, aud the animal may fall when moving about. 

 They soon present a gaunt, emaciated appearance. 



In dogs the diagnosis is confirmed by a microscopical exam- 

 ination of the vagus ganglia and that portion of the brain known 

 as Amnion's horn, and the finding of Xegri bodies in the nerve- 

 cells. In case a person is bitten by a dog, the animal should be 

 confined until the disease is well advanced and killed or allowed 

 to die. The head should then be removed and forwarded to 

 the State laboratory, or wherever such examinations are made. 



Tlie treatment is preventive. Wherever an outbreak of rabies 

 occurs all dogs should be confined on the owner's premises or 

 muzzled. All dogs running at large without muzzles should be 

 promptly killed. A heavy tax on 'dogs, and the killing of all 

 dogs not wearing a license tag, would prevent the heavy financial 

 loss resulting from rabies, and the ravages of wandering dogs in 

 the United States. In countries where the muzzling of dogs is 

 enforced during the entire year, rabies is a rare disease. 



Foot-and-mouth Disease. — This is a highly contagious and 

 infectious disease of cattle, sheep, goats and swine. It is charac- 

 terized by the eruption of vesicles on the mucous membrane lining 

 the mouth, the lips, between and above the claws and in the region 

 of the udder and perineum. Man may contract the disease by 

 caring for sick animals ; or by drinking raw milk from a sick 

 cow. Babies are most susceptible to infection from milk. 



Foot-and-mouth disease was introduced into eastern Europe 

 from the steppes of Piiissia and Asia near the end of the eigh-
