Pentastomids Of Wild Snakes In Australia, Crystal Kelehear, David M. Spratt, Denis O'Meally, Richard Shine

Harold W. Manter Laboratory of Parasitology: Library Materials

Pentastomids are endoparasites of the respiratory system of vertebrates, maturing primarily in carnivorous reptiles. Adult and larval pentastomids can cause severe pathology resulting in the death of their intermediate and definitive hosts. The study of pentastomids is a neglected field, impaired by risk of zoonoses, difficulties in species identification, and life cycle complexities. We surveyed wild snakes in the tropics of Australia to clarify which host species possess these parasites, and then sought to identify these pentastomids using a combination of morphological and molecular techniques. We detected pentastomid infections in 59% of the 81 snakes surveyed. The ubiquity of pentastomid …

Varestrongylus Eleguneniensis Sp. N. (Nematoda: Protostrongylidae): A Widespread, Multi-Host Lungworm Of Wild North American Ungulates, With An Emended Diagnosis For The Genus And Explorations Of Biogeography, Guilherme G. Verocai, Susan J. Kutz, Manon Simard, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Background: A putative new species of Varestrongylus has been recently recognized in wild North American ungulates based on the ITS-2 sequences of larvae isolated from feces during a wide geographic survey. No taxonomic description was provided, as adult specimens were not examined. Methods: Lungworm specimens were collected in the terminal bronchioles of muskoxen from Quebec, and a woodland caribou from central Alberta, Canada. The L3 stage was recovered from experimentally infected slugs (Deroceras spp.). Description of specimens was based on comparative morphology and integrated approaches. Molecular identity was determined by PCR and sequencing of the ITS-2 region of …

Air Sac Nematode Monopetalonema Alcedinis In A Belted Kingfisher (Megaceryle Alcyon) In Maryland, Usa, Ellen Bronson, Kathleen Kelly, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Sporadic and geographically widespread reports of parasites affecting the Belted Kingfisher (Megaceryle alcyon) have been published but few have described details of the pathology. A female, adult kingfisher was found dead in a heavily wooded area of a zoo in Maryland, USA. At necropsy, numerous sexually dimorphic, 4.4–40.5-cm adult Monopetalonema alcedinis nematodes were found tightly wound within the coelomic cavity between organs and completely filling the caudal thoracic and abdominal air sacs. Abundant, 30–60-mm diameter, larvated, thick-walled ova were found in the bronchi and parabronchi, within the mesentery, and in the serosa of multiple coelomic organs. Monopetalonema alcedinis …

Fate Of Antimicrobials And Antimicrobial Resistance Genes In Simulated Swine Manure Storage, Stacey R. Joy, Xu Li, Daniel D. Snow, John Gilley, Bryan L. Woodbury, Shannon L. Bartelt-Hunt

School of Natural Resources: Faculty Publications

The behavior of three antibiotics (bacitracin, chlortetracycline, and tylosin) and two classes of antibiotic resistance genes (ARGs), tet and erm, were monitored in swine manure slurry under anaerobic conditions. First-order decay rates were determined for each antibiotic with half-lives ranging from1 day (chlortetracycline) to 10 days (tylosin). ARGs were monitored in the swine manure slurry, and losses of approximately 1 to 3 orders of magnitude in relative abundance were observed during the 40 day storage period. First-order degradation profiles were observed for chlortetracycline and its corresponding resistance genes, tet(X) and tet(Q). Tylosin was degraded to approximately 10% …

Redescription Of Oligacanthorhynchus Microcephalus (Rudolphi, 1819) Schmidt 1972 (Syn. Oligacanthorhynchus Tortuosa (Leidy, 1850) Schmidt 1972) (Acanthocephala: Oligacanthorhynchidae), Dennis J. Richardson, Scott Lyell Gardner, Jonathan W. Allen Jr.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Oligacanthorhynchus microcephalus (Rudolphi, 1819) Schmidt, 1972 was originally described from the philander opossum Caluromys philander from Brazil. Oligacanthorhynchus tortuosa (Leidy, 1850) Schmidt, 1972 was originally described from the Virginia opossum (Didelphis virginiana) in North America. Six years after describing O. tortuosa, Leidy indicated the synonomy of O. tortuosa with O. microcephalus. This taxonomic view persisted for decades until Van Cleave, in 1924, recognized the validity of O. tortuosa, apparently without examining the type material of O. microcephalus. Subsequent workers have recognized two species of Oligacanthorhynchus from New World opossums: O. microcephalus from South American …

Some Aspects Of The Biology Of Monogenean (Platyhelminth) Parasites Of Marine And Freshwater Fishes, Graham C. Kearn

Harold W. Manter Laboratory of Parasitology: Library Materials

Müller was the first to describe a monogenean, collected from the skin of the halibut (Hippoglossus hippoglossus). However, he regarded the parasite as a leech and named it Hirudo hippoglossi. It was not until 1858 that its status as a monogenean was established by van Beneden and named Epibdella (now Entobdella) hippoglossi. Van Beneden published a detailed and accurate description of the parasite and one of his excellent illustrations is reproduced here. Entobdella hippoglossi is one of the largest monogeneans, measuring up to 2 cm in length. It has a smaller relative, measuring 5 to …

The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman

Honors Projects

Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cestodes collected from the spiral valves of the stingray Urotrygon sp. from the Pacific coast of Mexico were identified as Escherbothrium molinae Berman and Brooks, 1994. The first report of the species was from the Gulf of Nicoya and the Guanacaste coast, Costa Rica; this work represents the second report of the species since the original description and extends its distribution north to Acapulco, Guerrero, Mexico.

Reported Incidences Of Parasitic Infections In Marine Mammals From 1892 To 1978, John R. Felix

Zea E-Books Collection

The role of parasites in the lives and deaths of marine mammals has been scrutinized by biologists for decades, but the scientific literature prior to 1978 has been difficult to acquire and time-consuming to search. Now this new and extensive bibliography gives researchers a convenient resource for reviewing the classical literature on parasites of marine mammals so that historical infection prevalence and geographical distribution can be easily and properly assessed. This book contains detailed information about accepted (or suspected) taxonomic synonyms and geographical information about the host and/or parasite, covering the parasite groups Acanthocephala, Acarina, Anoplura, Cestoda, Nematoda, and Trematoda, …

Karl Reinhard Publications

Pathoecology provides unique frameworks for understanding disease transmission in ancient populations. Analyses of Old and New World archaeological samples contribute empirically to our understanding of parasite infections. Combining archaeological and anthropological data, we gain insights about health, disease, and the way ancient people lived and interacted with each other and with their environments. Here we present Old and New World parasite evidence, emphasizing how such information reflects the different ways ancient populations exploited diverse environments and became infected with zoonotic parasites. It is clear that the most common intestinal helminthes (worm endoparasites) were already infecting ancient inhabitants of the New …

Coccidia Of Gerbils From Mongolia, Ethan Thomas Jensen

School of Biological Sciences: Dissertations, Theses, and Student Research

In this study, gerbils collected in the Mongolia over the summers of 2009-2012 were examined for coccidia. In total, 171 gerbils of three species from 22 localities were examined for coccidia. Coccidian oocysts were identified from 21 gerbils, but those found in 1 of those gerbils were probably pseudoparasites of the host from which they were recovered. From the remaining 20 gerbils, 7 morphotypes of Eimeria and 1 morphotype of Isospora were identified. Four of the 7 morphotypes of Eimeria were attributed to new species which were described in this study. In addition, 10 previously described species of Eimeria were …

Ectoparasites Of The Virginia Opossum (Didelphis Virginiana), Raccoon (Procyon Lotor), And Striped Skunk (Mephitis Mephitis) From Keith County, Nebraska, Lance A. Durden, Dennis J. Richardson

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Six Virginia opossums (Didelphis virginiana), nine raccoons (Procyon lotor) and one striped skunk (Mephitis mephitis) collected from Keith County Nebraska were examined for ectoparasites. All three host species were parasitized by adults of the American dog tick, Dermacentor variabilis. Opossums were also parasitized by the flea Pulex simulans and the tiny fur mite Didelphilichus serri­fer; the latter species represents a new state record for Nebraska. Raccoons were also parasitized by P. simulans and by the lago­morph-associated flea Euhoplopsyllus glacialis affinis, whereas the skunk was also parasitized by the chewing louse Neotrichodectes …

Mycobacterium Bovis (Bovine Tuberculosis) Infection In North American Wildlife: Current Status And Opportunities For Mitigation Of Risks Of Further Infection In Wildlife Populations, Ryan S. Miller, Steven J. Sweeney

Zoonotics and Wildlife Disease: Publications

Mycobacterium bovis (M. bovis), the causative agent of bovine tuberculosis, has been identified in nine geographically distinct wildlife populations in North America and Hawaii and is endemic in at least three populations, including members of the Bovidae, Cervidae, and Suidae families. The emergence of M. bovis in North American wildlife poses a serious and growing risk for livestock and human health and for the recreational hunting industry. Experience in many countries, including the USA and Canada, has shown that while M. bovis can be controlled when restricted to livestock species, it is almost impossible to eradicate …

Diseases At The Livestock–Wildlife Interface: Status, Challenges, And Opportunities In The United States, Ryan S. Miller, Mathew L. Farnsworth, Jennifer L. Malmberg

Zoonotics and Wildlife Disease: Publications

In the last half century, significant attention has been given to animal diseases; however, our understanding of disease processes and how to manage them at the livestock–wildlife interface remains limited. In this study, we conduct a systematic review of the scientific literature to evaluate the status of diseases at the livestock–wildlife interface in the United States. Specifically, the goals of the literature review were three fold: first to evaluate domestic animal diseases currently found in the United States where wildlife may play a role; second to identify critical issues faced in managing these diseases at the livestock–wildlife interface; and third …

Efficacies Of Fenbendazole And Albendazole In The Treatment Of Commercial Turkeys Artificially Infected With Ascaridiadissimilis, Jessica Perkins

Animal Science Undergraduate Honors Theses

The goal of this research was to determine the extent of anthelmintic resistance that turkey roundworms, Ascaridiadissimilis, have developed to anti-parasitic chemicals used in commercial turkey operations. Roundworm infections in turkeys have resulted in monetary losses for the poultry industry for years, generally due to poor feed conversion. The infection itself is generally subclinical and many turkeys have a light to moderate worm burden. Since parasitisms are light, this leads to the infections being noticed only during processing.A. dissimilis infections consist of adult worms and developing larvae with the latter comprising most of the worm burden and causing the most …

Los Parásitos Y El Estudio De Su Biodiversidad: Un Enfoque Sobre Los Estimadores De La Riqueza De Especies, Christian E. Bautista-Hernández, Scott Monks, Griselda Pulido-Flores

Estudios científicos en el estado de Hidalgo y zonas aledañas

Durante años los parásitos fueron considerados únicamente como agentes patógenos que debían ser eliminados, sin considerar que son un componente importante de la biodiversidad, que son capaces de aportar información de sí mismos y de otros organismos. Existen estimadores de riqueza que predicen el número de especies para una comunidad a partir de la riqueza observada y de la abundancia de las especies o datos de incidencia; pueden ser estimadores paramétricos y no paramétricos. La comparación de la riqueza de especies entre componente de comunidades de parásitos frecuentemente pueden ser difícil de evaluar debido a que los datos no se …
