“…Juvenile animals are most susceptible to heavy infection upon first exposure, but rapidly develop acquired immunity to future S papillosus infections (Turner et al ., 1960). Case reports of strongyloidiasis due to naturally acquired infection are extremely rare, with only a few confirmed records (Romero et al ., 2022; Onyali e t al ., 1989; Round, 1963; Taira and Kato, 1986; Turner and Wilson, 1958; Woodhouse, 1948). However, there are also case reports of high-level and rapid death of calves, apparently due to Strongyloides infection, thought to be due to hyperinfection (Thamsborg et al ., 2017).…”

Strongyloides nematodes are parasites of livestock, and S. papillosus infects ruminant livestock that can cause disease. Recent genomic analysis of several Strongyloides species is now facilitating the population genomic analyses of natural Strongyloides infections, for example finding that S. ratti in wild UK rats exists as an assemblage of long-lived, asexual lineages. Here we have investigated the population genomics of S. papillosus in goats in Pakistan. We find that S. papillosus is common, with a prevalence of 28 %; that the population is genetically diverse and that individual goats commonly have mixed-genotype infections; and that there is evidence of only limited admixture. These results now provoke further questions about the host range of different S. papillosus genotypes that can in the future be investigated by further population genomic analyses.

“…Strongyloidiasis is a serious problem in healthcare and veterinary medicine [16]. In Europe, 22 species of Strongyloides genus are distributed, including S. papillosus (Wedl, 1856), found in cattle, pigs, sheep, goats, rabbits, polecats, and rats [17][18][19].…”

The food industry is not the only sphere of human activity where inorganic food additives are globally used. In certain concentrations, they are safe for people and agricultural animals. Nonetheless, they impose a negative impact on other classes of living organisms. Therefore, our objective was to determinine the influence of some inorganic food additives (alkalis, acids, salts) on the vitality of nematode larvae that parasitize agricultural animals: Strongyloides papillosus, Haemonchus contortus and Muellerius capillaris. We studied the effects of sodium hydroxide, potassium hydroxide, boric acid, phosphoric acid, potassium chloride, calcium chloride, sodium nitrite, potassium nitrite, sodium nitrate, potassium nitrate, ammonium bicarbonate, sodium bisulfite, sodium bisulfate, sodium sulfate, potassium sulfate, calcium sulfate, sodium thiosulfate, sodium metabisulfite, potassium metabisulfite, copper sulfate pentahydrate, tetrasodium pyrophosphate, sodium triphosphate, sodium borate decahydrate and talc. In in vitro experiments, the strongest effects were produced by alkalis sodium hydroxide and potassium hydroxide. In 24 h, 1% solutions of those substances killed 69% of larvae of S. papillosus, H. contortus and M. capillaris of various development stages. Sodium sulfate was effective against all stages of larvae of S. papillosus, and also against first-age M. capillaris. Nematocidal properties only against all stages of S. papillosus were exerted by copper sulfate pentahydrate. Non-invasive stages of S. papillosus nematodes were affected only by phosphoric acid, ammonium bicarbonate, calcium chloride, sodium nitrite, calcium sulfate, potassium metabisulfite, tetrasodium pyrophosphate, sodium triphosphate and the same stages of M. capillaris—by phosphoric acid, sodium bisulfite and potassium nitrite.
