Ascariasis is the infestation of swine by the roundworm, Ascaris suum, which can cause pneumonia, hepatitis, and ill thrift. Ascariasis occurs worldwide in countries that raise significant numbers of swine. All ages are affected but ascariasis is more severe in young, growing pigs.

The large roundworm of pigs (Ascaris suum) is the most common and widespread parasite of swine. Larval migration through the liver results in focal hepatitis (milk spots) and condemnation of the liver at slaughter but no clinical signs.

Ascaris suum, also known as the large roundworm of pig, is a parasitic nematode that causes ascariasis in pigs. While roundworms in pigs and humans are today considered as two species (A. suum and A. lumbricoides) with different hosts, cross-infection between humans and pigs is possible; some researchers have thus argued they are the same ...

2018年11月1日 · These roundworms are usually found in greatest numbers in pigs up to 2 to 3 months of age with a few in older pigs. Sows usually are not clinically affected, but serve as carriers. Roundworms are long (6 to 12 inches), stout, …

2024年6月3日 · The adult Ascaris suum worm lives in the pig’s intestines. They pass their eggs in the pigs’ feces (manure). Infected pigs deposit eggs into the soil whenever they defecate (poop). The eggs require days to weeks in the environment to become infective. When people or pigs consume the infective eggs, they become infected with Ascaris suum.

2022年6月7日 · Ascaris suum, also called the large pig roundworm or the large white worm, is a species of parasitic roundworms that infects pigs and wild boars worldwide. Prevalence is often very high, especially in tropical countries.

Antiparasitic drugs for pigs can be used to achieve one or more of four goals:1) to prevent parasitic infection of the host2) to remove parasites from the host in the absence of clinical parasitic3) to treat parasitic disease in the host4) to reduce contamination of the environment with parasite life cycle stages that can become infective for ot...

2015年1月21日 · Round worms in pigs are very similar to Ascaris lumbricoides (human) vs. Ascaris suum. Yes, people can be infected and the migration of the larvae cause disease. This is a significant zoonotic disease concern for people.

Ascaris suum, also called the large pig roundworm or the large white worm occur in gastrointestinal tracts, is a species of parasitic roundworms that infects pigs and wild boars [1, worldwide 2]. Adults are found in the small intestine and transitorily in the large intestine during expulsion of the worms.

6 天之前 · The most noticeable impact of a roundworm infestation is the competition for nutrients between the pig and the worm burden, often resulting in unthrifty pigs. Even pigs with a low roundworm burden may appear healthy but can show decreased performance in terms of feed conversion efficiency.
