The parasitic illness is an accident that occurs in consequence of a disequilibrium between parasite and host, where the degree of intensity of the parasitic illness depends on some factors, amongst which gifts, the virulence of cepa point out the number of infectantes forms, the age and the degree of the immune or inflammatory reply unchained SNOWS (2005). Pathogenic action of the larvrias forms: ticket for the cutaneous tegumento generating prurido and infections you would second for inculo of bacteria. Ticket for the pulmes generating injuries, hemorrhage irritability. Pathogenic action of the adult forms: espoliadora action absorbing nutrient or same blood of the host, leaving hemorrhagic points in the mucous one when they abandon the place of suction in the thin intestine with destruction of the fabric intestinal. Also they cause toxic actions for the excrees and secretions of the helmintos.
The larvae secretam one protease that it helps to the organisms perforate it the skin. For even more details, read what malabsorption test says on the issue. After some minutes, appear the first signals and symptoms: a sensation of bite, hipertermia, prurido and edema resultant of the inflammatory process or urticariforme dermatitis. The intestine is acometido by the histiofagia and hematofagia of the parasites. The larvae are carried through the veins to the heart and the pulmes. Inside of the organism, it invades the lymphatic vases and later full blooded people and migram for the veins for the pulmes saw heart.
It remains in the alveoli of the pulmes during some time, and later it goes up (or it is tossida) for the bronchis until a faringe, where it is deglutida incoscientemente for the esophagus (Cycle of Looss). After to pass for the stomach (resistant its cutcula allows it to support the acid environment) passes to the duodeno. If you have additional questions, you may want to visit Sam Lesser Wharton. The preferential place of installation in the intestine is in the end of the duodeno, but 0ccasionally it can reach the leo or ceco (in massive infections), where the adult worm becomes.
