Laboratory animals

Laboratory animals - animals that are also a range of medical, biological, veterinary, space and other laboratory tests.
Researches on certain sections of medicine and biology conducted on laboratory animals of a given species "traditional". Thus, in the experimental surgery use of dogs, histology - cats in physiology - dogs, rabbits, frogs and other animals, in Virology mice, monkeys, and other
Laboratory animals should be healthy, have specific characteristics (sensitivity to the investigated infections, sensitivity to the investigated poisonous substances etc), and also differ by a small amount, availability of treatment, cheapness breeding.
Special requirements to laboratory animals, which reveals the nature and causes of hereditary diseases, malignant tumors, conducted experiments on overcoming of tissue incompatibility with transplants of organs and tissues. For all these experiments, the necessity arose to eliminate laboratory animals pure lines (see). The number is now known lines of mice exceeds 400, lines of rats - a few dozen.
Lists of lines of all types of laboratory animals and their sources are published annually by the International Committee of laboratory animals to the public. Include laboratory animals in special rooms - vivaria (see).
For experimental address specific issues of biology and medicine, among vertebrates, the use of invertebrates. Often this is the simplest - ciliates (for example, pumps), amoeba, flagellates and other insects Such as fly Drosophila, used to address issues of variability, heredity, patterns of mutation process, etc. in Addition, the laboratories are widely used mosquitoes, mosquitoes, fleas, lice, flies; when studying migration of pathogens of human and animal diseases - exode and argatova ticks; when considering the issues related to the prevention and treatment of helminthes,- roundworm, Schistosoma and other helminths.
