The method of allocation of Toxocara canis larvae from parenchyma of liver and lung of carnivorous animals for postmortem diagnostics of toxocarosis is of-fered at a weak infection and in prepatent period. The received culture of larvae of T. canis can be used for studying pathogenesis of the diseases, carrying out genetic researches and receiving proteins with diagnostic and protective properties. The list of the equipment, reactants and solutions for allocation of T. canis larvae is given. The work course which consists of preparation of tests of tissue of a liver and lungs, preparation of artificial gastric juice, digestion of tissues, an assessment of the re-sults, concentration of T. canis larvae is described. For researches take samples of a parenchyma of lungs or a liver weighing 50 g, crush on a meat grinder. Samples digest to the current of 50 min. at a temperature of 41–42 °C. After 10 minute up-holding a deposit merge in Petri's cups and investigate on existence of T. canis lar-vae and their mobility. For concentration of a material a deposit centrifuge during 10 min.
