Bees and silkworms, ornamental and songbirds, fish bred in ponds and aquariums are close to pets. As it were, the transitional stage from wild animals to domestic animals is made up of spotted deer, red deer, red deer, pheasants, swans, etc. bred in semi-volatile conditions, and in the conditions of captivity foxes, foxes, minks and other fur animals, and also laboratory animals (see) .
The value of domestic animals for humans is very high. They serve as sources of the most important food products, in particular protein, - milk and dairy products are especially rich in them. Dairy products have dietary properties and are recommended for the treatment of certain diseases. So, with tuberculosis, stomach diseases, exhaustion, patients give koumiss. Lard, fat, lanolin are used as medicines or bases for their manufacture. Natural gastric juice is obtained from healthy dogs. Medicinal preparations are prepared from the tissues and organs of domestic animals: stimulants of the central nervous system ( pantocrinum , adrenaline , etc.), agents affecting blood coagulation (heparin), choleretic (allohol), and many others. A number of domestic animals serve as a “living factory” in the production of serums and vaccines. Laboratory animals used in a variety of experimental research.Go
Pets are of great epidemiological importance, as they can be a source of infection for people with various infections and invasions . The distribution of brucellosis , anthrax , foot and mouth disease, salmonellosis , tick-borne encephalitis and other diseases is associated with cattle and small cattle; horses, donkeys can infect glanders ; pigs - with anthrax, brucellosis, and helminthiasis - taeniasis and trichinosis ; dogs - rabies , as well as some helminthiasis (echinococcus). In the transfer of human plague can play the role of camels. Poultry matter in people suffering from salmonellosis; waterfowl (in particular, ducks), as well as pigeons, mainly transmit ornithosis .
Many diseases associated with domestic animals are primarily professional. Infection occurs when people come into contact with sick animals or objects of the external environment infected by them, when eating meat or milk of sick animals in a raw, half-baked form, as well as through arthropods that parasitize animals.
The risk of people becoming infected with pets increases during an epizootic situation if the necessary sanitary protective measures are not followed. Quarantine measures for the import of domestic animals from abroad, as well as measures for specific prophylaxis ( immunization of animals), are of great importance in the prevention of zoonoses .
