Vivarium

Vivarium - room for keeping laboratory animals. The device vivarium depends on laboratory animals (see) it contains, and what the research is conducted. Microbiological vivarium, as a rule, consists of five isolated premises (or groups of premises): a) for primary processing of incoming animals and their quarantine; b) for the maintenance of healthy animals; C) for keeping laboratory animals; d) for washing and sterilization of cages, feeders, bowls, etc; d) for cooking, storage of feed material for bedding, etc., In vivarium provide a laboratory for experiments, operating for dissection of animals, a warehouse for equipment and room for staff. The amount of areas for keeping of animals expected on the basis of the following indicators: 1 rabbit - 0.75 m3, 10 Guinea pigs or 15 rats - 3.5 m3, 1 dog 2 m3, 10 mice - 1.5 m3. Small animals must be kept in metal cages (Fig. 1) or low banks, closed metal lids with holes, easy to disinfect.
Size of cells: for rabbit - 50-70x40-50x40-50 cm; for Guinea pigs - 65-90 X 55 to 60 X 40 cm (cell plant, 7-8 pigs); for mice - 30-50x40x25 cm (cell plant, 7-8 mice). Dogs are kept in cages the size not less 2x2x2 m For feeding expedient to apply feeders, avtokraski and avtopoilki. Animals should be fed a standard combined feed. In some cases the animals are fed on the order of the experimenter.
The rooms for animals should be light, with a good supply-and-exhaust ventilation, with a constant temperature, humidity , etc. Premises of the vivarium must be built so that it was easy to clean. Flooring and walls made of materials which are easy to wash off the dirt. In the floor of the necessary waste grooves. Cleaning should be carried out with water under pressure of the hose. Waste water is collected in special tanks, it is filtered and sterilized. Vivarium protect against invasion of mice, rats, cats, dogs, and insects (flies, mosquitoes, horseflies and other). It is necessary to completely prevent the spread of infection among animals, if it will be recorded in the vivarium. To do this, a room for preparation and storage of food come away from the room for the primary processing of incoming animals; in the air handling unit room containing infectious or newly arrived animals, it is necessary to provide special filters to infectious agents could not spread through the air moves in the other premises of the vivarium and in environment; it should be kept in reserve cells to quarantine animals.
Animals, Tatralandia radioactive substances of different types, are contained in separate specially equipped premises: floor and wall to a height of 2 m should be covered with plastic or glazed tiles, ceilings and upper part of the walls are painted with oil paint. Animal cages are made from plastic or metal cover acid resistant varnishes, pallets in cells must be metal or plastic. Radioactive waste is put in a special sewage system with sewage treatment facilities or collected in special containers for deletion on disposal points.
Depending on the specifics of experiments must first develop the rules of work with animals to prevent the spread of the epidemic by employees of the vivarium or infecting their animal diseases. All employees must have clothing. When working with infectious animals are issued separate sets of clothing for work only in these areas. Near such areas arrange cloak with the Department for disinfection of the used clothing. Employees of the vivarium should observe personal hygiene rules (masks, gloves, thorough washing hands with disinfectant and so on) to avoid infection from animals.
Carcasses of dead animals must be burned.
For rendering of first aid in vivarium should have first-aid. When working with especially dangerous infections, with radioactive isotopes, and so on, the mode and rules of working in vivarium defined by special instructions.
