Differences In The Diversity Of Frogspecies Between Sierra Lloronaand El Valle, Panama, Kei Okabe Thurber

Independent Study Project (ISP) Collection

Panama is home to the greatest diversity of species in all of Central America. It is home to 174 species of frogs, 35 of which are endemic to Panama. Frogs are a vital part of many ecosystems. They maintain insect populations and act as food sources for larger predators. Their job of maintaining insect populations is essential to curbing the spread of diseases. Additionally, scientists have found chemical compounds in the skin of frogs that can be used to treat pain and prevent infections. The main threat to the majority of frogs is the deadly fungus Batrachochytrium dendrobatidis (Bd), or …

Birds are the most species-rich class of tetrapod vertebrates and have wide relevance across many research fields. We explored bird macroevolution using full genomes from 48 avian species representing all major extant clades. The avian genome is principally characterized by its constrained size, which predominantly arose because of lineage-specific erosion of repetitive elements, large segmental deletions, and gene loss. Avian genomes furthermore show a remarkably high degree of evolutionary stasis at the levels of nucleotide sequence, gene synteny, and chromosomal structure. Despite this pattern of conservation, we detected many non-neutral evolutionary changes in protein-coding genes and noncoding regions. These analyses …

Managing Devil Facial Tumour Disease In Tasmanian Devils (Sarcophilus Harrisii): An Investigation Of Heat Shock Proteins As Potential Vaccine Adjuvants, Monika Payerhin

Independent Study Project (ISP) Collection

The world’s largest carnivorous marsupial, the Tasmanian devil (Sarcophilus harrisii), is facing extinction from a deadly, highly communicable cancer that has already decimated over 85% of devil populations in the wild: devil facial tumour disease (DFTD). DFTD cells effectively evade recognition by the immune system, and every devil that contracts the disease dies from it. Many attempts have been made at developing a vaccine that could help save this now-threatened species. Heat shock proteins have been linked to enhanced immune recognition of pathogens, making them potential candidates for acting as adjuvants to such a vaccine against DFTD. In this study, …

Confluent IPEC-J2 monolayers were tested at five time intervals (0, 1, 2, …

Pathogenic Landscape Of Transboundary Zoonotic Diseases In The Mexico–Us Border Along The Rio Grande, Maria Dolores Esteve-Gassent, Adalberto A. Pérez De León, Dora Romero-Salas, Teresa Patricia Feria-Arroyo, Ramiro Patino, John A. Goolsby

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Transboundary zoonotic diseases, several of which are vector borne, can maintain a dynamic focus and have pathogens circulating in geographic regions encircling multiple geopolitical boundaries. Global change is intensifying transboundary problems, including the spatial variation of the risk and incidence of zoonotic diseases.The complexity of these challenges can be greater in areas where rivers delineate international boundaries and encompass transitions between ecozones.The Rio Grande serves as a natural border between the US State ofTexas and the Mexican States of Chihuahua, Coahuila, Nuevo León, andTamaulipas. Not only do millions of people live in this transboundary region, but also a substantial amount …

Landscape Genetics Of The Endangered California Tiger Salamander (Ambystoma Californiense) In The Los Vaqueros Watershed, Ryan Neal Vincent

Mahurin Honors College Capstone Experience/Thesis Projects

Genetic diversity is essential for maintaining healthy biological systems, and dispersal-mediated gene flow increases genetic diversity by introducing new alleles to a gene pool. Populations that frequently experience gene flow will show characteristic similarities in allele frequencies. Measuring genetic diversity among many populations across a landscape has proven to be a powerful approach for assessing the ways that habitat discontinuities may affect patterns of gene flow, and in turn, influence allele frequencies and population dynamics. This study examines the landscape-level population genetic structure of the California tiger salamander, Ambystoma californiense, within the Los Vaqueros Watershed of Contra Costa County, …

The Effects Of Heat Stress On Immunity In Laying Hens And Dairy Cattle, Rebecca Ann Strong

Open Access Theses

With the increase in global climate change and the population growth driving the high demand for additional food production, heat stress (HS) is a major concern in the livestock industry across all species. Animals experience HS when exposed to high environmental temperatures outside their thermal neutral zone. The level of the effects can vary due to the length and intensity of HS to which the animal is exposed to. In experiment one, laying hens with access to cooled perches during HS had a lower heterophil to lymphocyte ratio compared to the control hens after 4 h of acute heat stress, …

Genetics Of The Pig Tapeworm In Madagascar Reveal A History Of Human Dispersal And Colonization, Tetsuya Yanagida, Jean-François Carod, Yasuhito Sako, Minoru Nakao, Eric P. Hoberg, Akira Ito

Harold W. Manter Laboratory of Parasitology: Faculty Publications

An intricate history of human dispersal and geographic colonization has strongly affected the distribution of human pathogens. The pig tapeworm Taenia solium occurs throughout the world as the causative agent of cysticercosis, one of the most serious neglected tropical diseases. Discrete genetic lineages of T. solium in Asia and Africa/Latin America are geographically disjunct; only in Madagascar are they sympatric. Linguistic, archaeological and genetic evidence has indicated that the people in Madagascar have mixed ancestry from Island Southeast Asia and East Africa. Hence, anthropogenic introduction of the tapeworm from Southeast Asia and Africa had been postulated. This study shows that …

High Local Diversity Of Trypanosoma In A Common Bat Species, And Implications For The Biogeography And Taxonomy Of The T. Cruzi Clade, Veronika M. Cottontail, Elisabeth K. V. Kalko, Iain Cottontail, Nele Wellinghausen, Marco Tschapka, Susan L. Perkins, C. Miguel Pinto

Publications and Research

The Trypanosoma cruzi clade is a group of parasites that comprises T. cruzi sensu lato and its closest relatives. Although several species have been confirmed phylogenetically to belong to this clade, it is uncertain how many more species can be expected to belong into this group. Here, we present the results of a survey of trypanosome parasites of the bat Artibeus jamaicensis from the Panama´ Canal Zone, an important seed disperser. Using a genealogical species delimitation approach, the Poisson tree processes (PTP), we tentatively identified five species of trypanosomes – all belonging to the T. cruzi clade. A small monophyletic …

Dynamically-Expressed Prion-Like Proteins Form A Cuticle In The Pharynx Of Caenorhabditis Elegans, Julia B. George-Raizen, Keith R. Shockley, Nicholas F. Trojanowski, Annesia L. Lamb, David M. Raizen

Publications and Research

In molting animals, a cuticular extracellular matrix forms the first barrier to infection and other environmental insults. In the nematode Caenorhabditis elegans there are two types of cuticle: a wellstudied collagenous cuticle lines the body, and a poorly-understood chitinous cuticle lines the pharynx. In the posterior end of the pharynx is the grinder, a tooth-like cuticular specialization that crushes food prior to transport to the intestine for digestion. We here show that the grinder increases in size only during the molt. To gain molecular insight into the structure of the grinder and pharyngeal cuticle, we performed a microarray analysis to …

Recent Shifts In The Occurrence, Cause, And Magnitude Of Animal Mass Mortality Events, Samuel B. Fey, Adam M. Siepielski, Sébastien Nusslé, Kristina Cervantes-Yoshida, Jason L. Hwan, Eric R. Huber, Maxfield J. Fey, Alessandro Catenazzi, Stephanie M. Carlson

Dartmouth Scholarship

Mass mortality events (MMEs) are rapidly occurring catastrophic demographic events that punctuate background mortality levels. Individual MMEs are staggering in their observed magnitude: re- moving more than 90% of a population, resulting in the death of more than a billion individuals, or producing 700 million tons of dead biomass in a single event. Despite extensive documentation of individual MMEs, we have no understanding of the major features characterizing the occurrence and magnitude of MMEs, their causes, or trends through time. Thus, no framework exists for contextualizing MMEs in the wake of ongoing global and regional perturbations to natural systems. Here …

Production Of Recombinant Human Coagulation Factor Ix By Transgenic Pig, Weijie Xu

Department of Chemical and Biomolecular Engineering: Dissertations, Theses, and Student Research

Hemophilia B is the congenital bleeding disorder caused by deficiency in functional coagulation factor IX (FIX) and about 28,000 patients worldwide in 2012. And current treatment is restricted to protein-replacement therapy, which required FIX concentrates for patients’ life-time. Approximately 1 billion units FIX were consumed in 2012. However, still about 70-80% patients, mostly in developing countries, received inadequate or no treatment because of the unavailable and/or unaffordable FIX concentrates. Considering safety reasons, e.g. transmission of blood-borne diseases, the recombinant human FIX (rFIX) is recommended other than the plasma-derived FIX. However, only one rFIX is currently available on the market. The …

An Hsi Fact Sheet: Avian Influenza In India, Humane Society International

HSI FACT SHEETS

Avian influenza (AI), commonly known as bird flu, typically causes little or no harm to its wild waterfowl hosts. In 2003-2004, however, nine Asian countries reported unprecedented outbreaks of high-mortality AI in domestic poultry. This viral lineage, subtype H5N1, has spread to over 60 countries, and is considered endemic in at least four.

In India, H5N1 outbreaks were first recorded in 2006, and have continued each year since, reaching a total of 86 by 2012. Millions of India’s chickens and ducks have been culled in efforts to contain and eliminate the virus. India has declared itself free of AI a …

Bovine respiratory disease (BRD) is the leading cause of illness and death in U.S. feedlot cattle. This study evaluated the use of isoflupredone acetate in the treatment of BRD. Crossbred male beef calves (n = 192; BW = 221 ± 3.9 kg) were acquired in two blocks from regional auction markets and transported to the University of Arkansas Stocker and Receiving Cattle Unit. Calves were observed daily for signs of respiratory illness. Antibiotic treatment was administered if calves displayed signs of respiratory illness and rectal temperature was ≥ 40 °C. Calves (n = 72) requiring antibiotic treatment were assigned randomly …

Alteration Of Host Cell Ubiquitination By The Intracellular Bacterial Pathogen Coxiella Burnetii, Lindsey Elizabeth Pritchett

Poultry Science Undergraduate Honors Theses

The intracellular bacterial agent of Q fever, Coxiella burnetii, replicates within a phagolysosome-like parasitophorous vacuole (PV) in human macrophages and delivers effector proteins to the host cytosol via a Dot/Icm type IV secretion system (T4SS). T4SS effectors are critical for PV formation and prevention of host cell death that allows sufficient time for bacterial replication. Recruitment of ubiquitin-related components to the C. burnetii PV is also predicted to be involved in PV formation and bacterial replication and is likely controlled by effector proteins. In this study, we assessed the role of the Dot/Icm T4SS in regulating ubiquitination by comparing subcellular …

Poultry Performance And Food Safety Impacts Of Selected Organic Acids And Probiotics, Anita Menconi

Graduate Theses and Dissertations

Improving production parameters and controlling foodborne pathogens have been challenges to the poultry industry. Salmonella has been the most common bacterial pathogen in laboratory confirmed foodborne illness cases, and contaminated poultry and poultry products have been identified as the most important source of transmission of Salmonella to humans. Therefore, research on effective interventions to reduce Salmonella transmission at the poultry production level has gained attention. Initially, a series of studies was conducted to evaluate the use of selected organic acids in controlling foodborne pathogens and improving poultry performance. Then, the characterization and application of lactic acid bacteria and Bacillus spp. …

Abstract

Plagioscion squamosissimus (Heckel 1840), a fish endemic to the Amazon Basin and commonly known as the “silver croaker,” plays an important role in the ecology and economy of Pará State, Brazil. Knowledge of host-parasite relationships is important to understanding the role of parasites in the control of natural host populations. This work describes histopathological aspects caused by several common intestinal parasites found during a helminthological survey of fish in northern Brazil. We observed a high prevalence of helminth infection, especially by J₃ nematode juveniles of the family Anisakidae and metacestodes of the family Protocephalidae (both with 100% prevalence). …
