This paper focuses on the study of Ascaris Suum infection to a pig population in the Argeș county, Romania. The pathologies produced by this parasite in the digestive and nervous systems of pigs have a special impact in terms of public health, namely the consumption of meat by the human population. The products obtained from the slaughter of these infested animals will contain deficient nutrients, from a qualitative point of view. The research is based on the surveillance of animals from 6 households, infested and subsequently treated with Ascatrix and Dectomax in order to finally obtain effective results after the administration of Doramectin, a substance whose role is to annihilate the electrical activity of nerve and muscle cells, at nematodes and arthropods, causing paralysis and parasite death, while piperazine adipate is more effective in parasites and eliminate them in living form. All this is demonstrated in this article in order to further study the presence of morphine in female Ascaris Suum larvae, and thus increased resistance of the microorganism in the host body.
