A single infection of pigs with Hyostrongylus rubidus results in a population of adult worms which is limited in numbers, probably as the result of a loss of worms . Although some (eg, Ascarops strongylina, Physocephalus sexalatus) are more obvious grossly, only Hyostrongylus rubidus is considered to be pathologically. Vet Rec.

They are found worldwide, but incidence varies strongly depending on the region. Hyostrongylus rubidus has a rubidsu life cycle. Sows repeatedly infected with large single doses of third stage infective Hyostrongylus rubidus larvae show an anamnestic circulating agglutinin response to the parasite as detected by the passive haemagglutination reaction.

The parasitic burden, as determined by the duration of egg laying and total egg output, was considerably lower for the group reared on the infected mothers. Adult Hyostrongylus rubidus are rather small worms, usually not longer than 10 mm, and have a reddish color because they suck blood. This article has been cited by other articles in PMC.
