Taxonomic Review Of The Wingmite Genus Cameronieta (Acari: Spinturnicidae) On Neotropical Bats, With A New Species From Northeastern Brazil, Juliana C. Almeida, Donald D. Gettinger, Scott Lyell Gardner

Scott L. Gardner Publications

The ectoparasitic mite genus Cameronieta (Acari: Mesostigmata: Spinturnicidae) is endemic to the New World and associated exclusively with bats of the family Mormoopidae. The genus consists of 7 species, 4 broadly distributed through the Caribbean and mainland of North and South America, and 3 species limited to the Greater Antilles archipelago. We present a brief review of the taxonomic history, redefine the genus, and consider some questions that remain concerning the biology and systematics of the group. A new species, Cameronieta almaensis n. sp., is described from the wings of Pteronotus parnellii collected from the Serra das Almas Reserve, in …

Phylogeny And Biogeography Of Species Of Syphacia Seurat, 1916 (Nemata : Oxyurida : Oxyuridae) From The Australian Bioregion, Haylee J. Weaver, Scott Monks, Scott Gardner

Scott L. Gardner Publications

Pinworm nematodes of the genus Syphacia (Nemata : Oxyurida : Oxyuridae) have a global distribution, and infect the caecum of rodents. Within the Australian Bioregion, 17 species of Syphacia infect a range of rodent hosts. Pinworms are traditionally thought to have coevolutionary relationships with their hosts, but the evolution and dispersal of Australian rodents and their helminths remains unclear. This combination of factors allowed us to investigate the likely relationships of Australian Syphacia species based on phylogenetic analysis, overlaid with the ecology and relationships of host species. We conducted a phylogenetic analysis using morphological characters of the species of Syphacia …

Baylisascaris Larva Migrans, Kevin R. Kazacos

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Zoonotic diseases, such as baylisascariasis, are receiving increasing attention as components of disease emergence and resurgence (Kazacos, 2001). Baylisascariasis is caused by the roundworm Baylisascaris procyonis and is one of the more recent zoonotic disease developments. This disease remains one of the least known and poorly understood zoonotic diseases, yet over the past several decades it has become widespread. It originated in wildlife species and is now well established as a human malady. Baylisascariasis is transmitted to humans via consumption of contaminated feces, and the role of wildlife (primarily raccoons) in this transmission process is becoming more clearly known and …

A New Feather Mite Species Of The Genus Trouessartia Canestrini (Acariformes: Trouessartiidae) From The Northern Rough-Winged Swallow Stelgidopteryx Serripennis (Passeriformes: Hirundinidae) In Pennsylvania, S. V. Mironov, R. M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new feather mite species, Trouessartia stelgidopteryx sp. n. (Astigmata: Trouessartiidae), is described from the Northern rough-winged swallow Stelgidopteryx serripennis Newton (Passeriformes: Hirundinidae) in Pennsylvania, USA. The new species is close to the minutipes species group and differs from its representatives and all other known species of the genus Trouessartia in having a unique combination of features in males: the opisthosomal lobes are much longer than wide, they are separated by a large semi-ovate terminal cleft, and their lobar apices bear semi-ovate terminal lamellae with a smooth margin.

Trematode Diversity In Freshwater Fishes Of The Globe Ii: “New World”, Anindo Choudhury, M. Leopoldina Aguirre-Macedo, Stephen S. Curran, Margarita Ostrowski De Núñez, Robin M. Overstreet, Gerardo Pérez-Ponce De León, Cláudia Portes Santos

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We provide a summary overview of the diversity of trematode parasites in freshwater fishes of the “New World,” i.e. the Americas, with emphasis on adult forms. The trematode fauna of three regions, South America, Middle America, and USA and Canada (North America north of Mexico), are considered separately. In total, 462 trematode species have been reported as adults from the Americas. The proportion of host species examined for parasites varies widely across the Americas, from a high of 45% in the Mexican region of Middle America to less than 5% in South America. North and South America share no adult …

Description Of Three Species Of Isorchis (Digenea: Atractotrematidae) From Australia, Michael J. Andres, Eric E. Pulis, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Three species of Isorchis Durio and Manter, 1969 are described from Australian waters. Isorchis megas sp. nov. is described from the spotbanded scat, Selenotoca multifasciata (Richardson), off Western Australia (WA) and Northern Territory (NT); Isorchis currani sp. nov. is described from S. multifasciata off NT; and Isorchis anomalus sp. nov. is described from the milkfish, Chanos chanos Forsskål, off WA. Isorchis megas sp. nov. can be differentiated from the other species of Isorchis by possessing a single, large egg that is greater than 20% of the body length; having a shorter body (the largest specimen is less than 500 μm); …

Paleoparasitological Evidence Of Pinworm (Enterobius Vermicularis) Infection In A Female Adolescent Residing In Ancient Tehran (Iran) 7000 Years Ago, Niloofar Paknazhad, Gholamreza Mowlavi, Jean Dupouy Camet, Mohammad Esmaeili Jelodar, Iraj Mobedi, Mahsasadat Makki, Eshrat Beigom Kia, Mostafa Rezaeian, Mehdi Mohebali, Siamak Sarlak, Faezeh Najafi

Harold W. Manter Laboratory of Parasitology: Library Materials

Background: The Molavi street archeological site south of Tehran, Iran accidentally provided a unique opportunity for paleoparasitological studies in Iran. A female skeleton was unearthed and evaluated to be 7,000 years old. Soil samples were collected around the pelvic and sacrum bones.

Findings: Careful microscopic investigation of rehydrated soil samples revealed the presence of one Enterobius vermicularis egg attached to the skeleton sacral region.

Conclusion: The present finding likely represents the oldest evidence of a human pinworm infection in Asia.

High Diversity Of Trypanosoma Cruzi Discrete Typing Units Circulating In Triatoma In Western Mexico, Uyen T. Nguyen

All Master's Theses

Chagas disease is caused by the protozoan parasite Trypanosoma cruzi, which is transmitted to domestic and sylvatic mammals via the feces of hematophagous hemiptera of the subfamily Triatominae (Reduviidae). Trypanosoma cruzi is found only in the Americas and displays remarkable genetic diversity. Seven discrete typing units (DTUs) are currently recognized (TcI–TcVI and TcBat). In Jalisco, Mexico, where Chagas disease has a high prevalence rate, TcI has historically been the only DTU reported. This study focused on the molecular identification of T. cruzi DTUs circulating in Triatoma near the Estación de Biología Chamela, on the southwest coast of Jalisco, Mexico. …

Analysis Of Fy Promoter And Hepatocystis Load In South African Vervet Monkeys (Chlorocebus Aethiops), Benjamin J. Gombash

All Master's Theses

There are species of Hepatocystis and Plasmodium, related blood parasites, that enter the cell through a chemokine receptor, coded for by the Duffy antigen/receptor for chemokines in humans, and the FY*0 (FY Null) allele in the promoter of this gene results in the absence of this receptor on the exterior of the cell (Miller et al., 1977; Miller et al., 1975; Miller et al., 1976; Barnwell et al., 1989; Perkins and Schall, 2002; Martinsen et al., 2008; Tung et al., 2009). Humans without the receptor show resistance to multiple strains of Plasmodium (Tournamelle, et al., 1995; Zimmerman, et al. …
