Swine roundworm disease
The pig-like roundworm is the only species of nematodes among parasites that have 2 parasitic generations (females are located in the small intestine) and each generation can live freely (males and females live in the surrounding environment), which can be transmitted through the skin, so hygiene needs to be taken seriously. In addition, nematodes can also be infected by infectious larvae in the colostrum of sows, so ingestion of colostrum is a more common infection route for newborn piglets to infect Ringworm, even if the sow does not have re-infection, the dormant larvae in their udders can also be transmitted to newborn piglets. Adults parasitize by burrowing into the wall of the small intestine. Depending on the mode of infection, the incubation period varies from 4 to 9 days. In mild and moderate infection, affected pigs generally do not show clinical symptoms. Piglets infected by the skin, due to the physical stimulation of the body surface by the larvae, often show rash and dermatitis, when the larva invades the lungs, its activity will affect the integrity of the alveoli, pigs show pneumonia symptoms, inflammatory areas can spread when the pleura can cause effects, causing pleurisy, pig breathing difficulties, body temperature rises, sometimes cough, asthma, decreased feeding intake, the body due to insufficient nutritional supply and slow growth and development. When a large number of Lan's roundworm bodies parasitize the intestines of piglets, they will destroy the intestinal mucosa at this location and cause hyperemia, and cause catarrhal enteritis, and in severe cases, erosive ulcers will appear, and the contents of the intestine will be foul-smelling, showing symptoms such as indigestion, anemia, loss of appetite, and diarrhea. Without effective treatment, most pigs eventually die of exhaustion.
