Pinworms infected Ancestral Pueblo populations since early periods of occupation on the Colorado Plateau. The high prevalence of pinworm found in these populations was correlated with the habitation style developments through time. However, in previous studies, Turkey Pen Cave, an early occupation site, and Salmon Ruins, a late occupation site, exhibited prevalences that were anomalously low, suggesting that these sites were outliers. Alternatively, it is possible that the previous quantification method was not successful in detecting the real prevalence and eggs per gram, which led to inexact interpretations. The aims of this study were to verify if previous pinworm prevalences …

There is often the risk of confusing pollen grains with helminth eggs from archaeological sites. Thousands to millions of pollen grains can be recovered from archaeological burial sediments that represent past ritual, medication and environment. Some pollen grain types can be similar to parasite eggs. Such a confusion is represented by the diagnosis of enterobiasis in ancient Iran. The authors of this study confused a joint-pine (Ephedra spp.) pollen grain with a pinworm egg. This paper describes the specific Ephedra pollen morphology that can be confused with pinworm eggs.
The Paleoepidemiology Of Enterobius Vermicularis (Nemata: Oxyuridae) Among The Loma San Gabriel At La Cueva De Los Muertos Chiquitos (600–800 Ce), Rio Zape Valley, Durango, Mexico, Johnica J. Morrow, Karl Reinhard

One hundred coprolites excavated from La Cueva de los Muertos Chiquitos (600–800 CE) in the Rio Zape Valley of present-day Durango, Mexico, were examined for the presence of helminth eggs utilizing standard archaeoparasitological techniques. Eggs of the human pinworm (Enterobius vermicularis) were recovered from 34 of the 100 coprolites examined. Eggs of parasites were photographed and measured before egg concentration values were calculated for each positive sample. Egg concentration values demonstrated an overdispersed pattern of distribution among the samples (66% uninfected, 25% less than 100 eggs/g, 8% between 100 and 500 eggs/g, and 1% more than 500 eggs/g). …

Investigations of Enterobius sp. infection in prehistory have produced a body of data that can be used to evaluate the geographic distribution of infection through time in the Americas. Regional variations in prevalence are evident. In North America, 119 pinworm positive samples were found in 1,112 samples from 28 sites with a prevalence of 10.7%. Almost all of the positive samples came from agricultural sites. From Brazil, 0 pinworm positive samples were found in 325 samples from 7 sites. For the Andes region, 22 pinworm positive samples were found in 411 samples from 26 sites for a prevalence of 5.3%. …
