Levamisole can be used in a large number of domestic animals such as sheep, goats, cattle, horses, pigs, poultry, dogs and cats as well as wild animals as a drug completely effective in the neonatal and pubertal stages of most gastrointestinal and respiratory nematodes. Animals such as Homoncus, Strategica trichostrongilus, and Coperia are known. Levamisole also has a significant effect on dictiococcus pneumoniae, and is the only anthelmintic in sheep for use against lungworms. 15 mg per kg orally and 15 days later an injectable dose will kill the worm and its eggs. Vamisol has little effect on small or large estrogens. In dogs, a dose of 15 mg per kg reduces toxocaracinosis, and ascariasis by 91%, and also repels hookworms. In cats, at a dose of 8 mg per kg, it is effective against ascariasis and hookworm. In poultry, it causes a 95% reduction in Scaridia galli, and Hethrax gallinarum and capillary, if consumed in the amount of 36-49 mg per kg. In addition to its extensive antiparasitic properties, levamisole, with its known immunogenic properties, increases the resistance of the animal body, and thus helps in the treatment of certain diseases in humans and animals. Levamisole is effective in boosting the immune system by increasing the number and function of T lymphocytes and macrophages and can stimulate antibody production, increase macrophage xenophagy, inhibit tumor growth, and enhance inhibitory cell activity.
