Taphonomic Considerations On Pinworm Prevalence In Three Ancestral Puebloan Latrines, Morgana Camacho, Alena M. Iñiguez, Karl Reinhard

Karl Reinhard Publications

For archaeological studies it is always necessary to consider taphonomic factors that could have influenced in ancient material preservation. Parasite eggs are usually highly degraded in ancient sites dated from all periods of time and taphonomic factors are mentioned to explain absence and low quantity of eggs found. In this study, we compare parasite egg recovery of three Great House latrines: two from Aztec Ruins (Rooms 219 and 225) and one from Salmon Ruins. We compared through statistical regression the recovery of eggs with the abundance of two classes of decomposers: mites and nematodes. These microorganisms have relation with nematode …

New Evidence Of Ancient Parasitism Among Late Archaic And Ancestral Puebloan Residents Of Chaco Canyon, Rachel E. Paseka, Carrie C. Heitman, Karl Reinhard

Karl Reinhard Publications

Archaeoparasitology provides a unique perspective on the health and habits of ancient cultures through the identification of parasite remains in archaeological materials. We identified eggs of the human whipworm, Trichuris trichiura, in coprolites recovered from Late Archaic (1926–1751 cal. BCE) and Ancestral Puebloan (1039–1163 cal. CE) sites in Chaco Canyon, New Mexico. Our findings represent the earliest record of T. trichiura in North America, the first record of the species from Chaco Canyon, and the first record of a macroparasite from a Late Archaic site (Atlatl Cave) on the Colorado Plateau. T. trichiura is common in the …

Abstract

The helminthological examination of nine individuals of Aetobatus cf. narinari (spotted eagle ray; raya pinta; arraia pintada) revealed the presence of an undescribed species of cestode of the genus Acanthobothrium. The stingrays were collected from four locations in México: Laguna Términos, south of Isla del Carmen and the marine waters north of Isla del Carmen and Champotón, in the State of Campeche, and Isla Holbox, State of Quintana Roo. The new species, nominated Acanthobothrium marquesi, is a category 3 species (i.e, the strobila is long, has more than 50 proglottids, the numerous testicles greater than 80, and has …

Immunoglobulin Therapy And Primary Immunodeficient Patients' Health-Related Quality Of Life And Well-Being, Niedre Heckman

Walden Dissertations and Doctoral Studies

Individuals born with primary immune deficiency diseases (PIDD) have a dysfunctional immune system, and many are treated by lifelong injections of immunoglobulin therapy. Studies have shown that these patients have low health-related quality of life (HRQOL) and well-being (WB) and that these outcomes might be improved by the availability of therapy innovated according to preferences for fewer needle sticks or a shorter infusion time. Regulators at the U.S. Food and Drug Administration (FDA) have approved therapies innovated per these preferences. However, there is limited data demonstrating how these innovations impact HRQOL and WB. Using the biopsychosocial model, the purpose of …

Twenty Years Of Spayvac® Research: Potential Implications For Regulating Feral Horse And Burro Populations In The United States, Ursula S. Bechert, Mark A. Fraker

Human–Wildlife Interactions

There are currently >75,000 feral horses (Equus ferus caballus) and burros (E. asinus ) on U.S. public lands, yet the Appropriate Management Level (AML) is set at just under 27,000. Wildlife managers, conservation biologists, and livestock ranchers are concerned about the impacts that these free-ranging horses have on shared rangelands. Immunocontraceptive vaccines may have the greatest potential to regulate horse population numbers once AML is reached; however, the vaccine must have multi-year efficacy to be both technically feasible and cost-effective. Immunocontraception based on porcine zona pellucida (PZP)-specific antigens is highly tissue-specific, targeting the ova, and blocking sperm binding through antibody …
