Development And Validation Of A Taqman Real-Time Reverse Transcription-Pcr For Rapid Detection Of Feline Calicivirus, M Abd-Eldaim, Rebecca Wilkes, K Thomas, Melissa Kennedy Oct 2012

Development And Validation Of A Taqman Real-Time Reverse Transcription-Pcr For Rapid Detection Of Feline Calicivirus, M Abd-Eldaim, Rebecca Wilkes, K Thomas, Melissa Kennedy

Rebecca P. Wilkes DVM, PhD, DACVM

Feline calicivirus (FCV) is a common cause of upper respiratory tract disease in cats and is associated with interstitial pneumonia, oral ulceration and polyarthritis. Recently, outbreaks have involved a highly virulent FCV that leads to multisystemic signs. Virus isolation and conventional RT-PCR are the most common methods used for FCV diagnosis. However, real-time RT-PCR offers a rapid, sensitive, specific and easy tool for nucleic acid detection. The objective of this study was to design a TaqMan probe-based, real-time RT-PCR assay for detection of FCV. It was determined in our previous study that the first 120 nucleotides of the 5' region ...

Fall Field Report, August-November 2009, W. Ross Silcock Dec 2009

Fall Field Report, August-November 2009, W. Ross Silcock

Nebraska Bird Review

This was probably the most "normal" fall season in a while, as measured by the small number of late departure dates among summer residents and migrants, early arrival dates among winter residents and migrants, high counts, and rarities. In other words, very little of significance happened. Indeed, in order to provide a spark, I'll even mention three exotics that were reported: a Swan Goose at Fremont 26 November (JRo), a Common Peafowl in Dodge Co 5 August (JWe), and a White-faced Cockatiel caught in a Dixon Co yard 24 August (JJ). None is likely to be a threat to ...

Relationship Between Tissue Carotenoid Concentrations In The Pacific Mole Crab, Emerita Analoga, And Parasitism By The Acanthocephalan, Profilicollis Altmani, Whitney Melroy Dec 2009

Relationship Between Tissue Carotenoid Concentrations In The Pacific Mole Crab, Emerita Analoga, And Parasitism By The Acanthocephalan, Profilicollis Altmani, Whitney Melroy

Biological Sciences

Acanthocephalan worms infect two hosts to reach full development. Some species have been demonstrated to change their intermediate host’s behavior or coloration to increase the likelihood they will reach the final host. The pacific mole crab, Emerita analoga, is commonly parasitized by Profilicollis altmani along the Pacific coast of North and South America, but the impact of parasitism on the crab intermediate host is unclear. We investigated whether P. altmani alters the concentration of dietary carotenoids present in E. analoga tissues and if the parasite may also acquire pigments normally allocated to the host. Fifty eight gravid female crabs ...

The Fish Crow (Corvus Ossifragus) Reaches Nebraska, Joel G. Jorgensen, Melissa J. Panella, W. Ross Silcock, Kristal J. Stoner Dec 2009

The Fish Crow (Corvus Ossifragus) Reaches Nebraska, Joel G. Jorgensen, Melissa J. Panella, W. Ross Silcock, Kristal J. Stoner

Nebraska Bird Review

The Fish Crow (Corvus ossifragus) was formerly endemic to the southeastern United States where it inhabited coastal areas along the Atlantic and Gulf Coasts (McGowan 2001). Since the early 1900s, the species has steadily expanded north and west along major river systems (McGowan 2001). Fish Crow range expansion has followed a logical pattern, expanding along major rivers in regions close to established populations, in adjacent states to the south and east of Nebraska. The species was first recorded in Missouri in 1964 (Robbins and Easterla 1992). In 1984, Fish Crow was first reported in Kansas and by 1991 was found ...


Genetic Susceptibility To Chronic Wasting Disease In Free-Ranging White-Tailed Deer: Complement Component C1q And Prnp Polymorphisms, Julie A. Blanchong, Dennis M. Heisey, Kim T. Scribner, Scot V. Libants, Chad Johnson, Judd M. Aiken, Julia A. Langenberg, Michael D. Samuel Dec 2009

Genetic Susceptibility To Chronic Wasting Disease In Free-Ranging White-Tailed Deer: Complement Component C1q And Prnp Polymorphisms, Julie A. Blanchong, Dennis M. Heisey, Kim T. Scribner, Scot V. Libants, Chad Johnson, Judd M. Aiken, Julia A. Langenberg, Michael D. Samuel

Natural Resource Ecology and Management Publications

The genetic basis of susceptibility to chronic wasting disease (CWD) in free-ranging cervids is of great interest. Association studies of disease susceptibility in free-ranging populations, however, face considerable challenges including: the need for large sample sizes when disease is rare, animals of unknown pedigree create a risk of spurious results due to population admixture, and the inability to control disease exposure or dose. We used an innovative matched case–control design and conditional logistic regression to evaluate associations between polymorphisms of complement C1q and prion protein (Prnp) genes and CWD infection in white-tailed deer from the CWD endemic area in ...


Hydrodynamics Of Freshwater Turtles: Maneuverability, Stability, And Effects Of Shell Shape, Gabriel Rivera Dec 2009

Hydrodynamics Of Freshwater Turtles: Maneuverability, Stability, And Effects Of Shell Shape, Gabriel Rivera

All Dissertations

Aquatic organisms exhibit tremendous diversity in body design and modes of propulsion that can strongly influence locomotor performance. Understanding how such differences affect locomotor performance is a major focus of research in integrative organismal biology and can provide insight into the evolutionary origins of such variation. Turtles are unique among extant tetrapods (i.e., amphibians, reptiles, birds, and mammals) in that they possess rigid bodies. In turtles, the vertebrae are fused dorsally with a bony carapace, precluding movement of the axial skeleton between the base of the neck and the tail. As a result of their immobilized axial skeleton and ...


Histomonas Meleagridis And Capillarid Infection In A Captive Chukar (Alectoris Chukar), J Reis Jr., R Beckstead, C Brown, Richard Gerhold Jr. Nov 2009

Histomonas Meleagridis And Capillarid Infection In A Captive Chukar (Alectoris Chukar), J Reis Jr., R Beckstead, C Brown, Richard Gerhold Jr.

Richard W. Gerhold Jr., DVM, MS, PhD

A female, adult, pen-raised chukar (Alectoris chukar) was submitted for postmortem examination. The main gross findings were severe emaciation, coelomic cavity and pericardial edema, and a large, sharply demarcated area of necrosis in the liver. Histologically, the liver lesions were characterized by areas of severe necrosis and inflammation containing numerous protozoal organisms morphologically consistent with Histomonas meleagridis. There was necrotizing typhlitis, with few histomonads and scant Heterakis spp. worms, in the cecum. Numerous aphasmid organisms, consistent with capillarids, were present in the crop and esophageal mucosa. Histomonas meleagridis was identified from frozen samples of liver by polymerase chain reaction and ...


Where Are The Parasites? [Letters], Susan J. Kutz, Andy P. Dobson, Eric P. Hoberg Nov 2009

Where Are The Parasites? [Letters], Susan J. Kutz, Andy P. Dobson, Eric P. Hoberg

Faculty Publications from the Harold W. Manter Laboratory of Parasitology

First paragraph:

The review by E. Post et al. ("Ecological dynamics across the Arctic associated with recent climate change," 11 September 2009, p. 1,355) paid little heed to parasites and other pathogens. The rapidly growing literature on parasites in arctic and subarctic ecosystems provides empirical and observational evidence that climate-linked changes have already occurred. The life cycle of the protostrongylid lungworm of muskoxen, Umingmakstrongylus pallikuukensis, has changed, and the range of that organism and the winter tick, Dermacentor albipictus, has expanded.


The Importance Of Fallback Foods In Primate Ecology And Evolution, Paul J. Constantino, Barth W. Wright Nov 2009

The Importance Of Fallback Foods In Primate Ecology And Evolution, Paul J. Constantino, Barth W. Wright

Biological Sciences Faculty Research

The role of fallback foods in shaping primate ranging, socioecology, and morphology has recently become a topic of particular interest to biological anthropologists. Although the use of fallback resources has been noted in the ecological and primatological literature for a number of decades, few attempts have been made to define fallback foods or to explore the utility of this concept for primate evolutionary biologists and ecologists. As a preface to this special issue of the American Journal of Physical Anthropology devoted to the topic of fallback foods in primate ecology and evolution, we discuss the development and use of the ...

Individual Variation In Baseline And Stress-Induced Corticosterone And Prolactin Levels Predicts Parental Effort By Nesting Mourning Doves, David A. Miller, Carol M. Vleck, David L. Otis Oct 2009

Individual Variation In Baseline And Stress-Induced Corticosterone And Prolactin Levels Predicts Parental Effort By Nesting Mourning Doves, David A. Miller, Carol M. Vleck, David L. Otis

Ecology, Evolution and Organismal Biology Publications

Endocrine systems have an important mechanistic role in structuring life-history trade-offs. During breeding, individual variation in prolactin (PRL) and corticosterone (CORT) levels affects behavioral and physiological processes that drive trade-offs between reproduction and self-maintenance. We examined patterns in baseline (BL) and stress induced (SI; level following a standard capture-restraint protocol) levels of PRL and CORT for breeding mourning doves (Zenaida macroura). We determined whether the relationship of adult condition and parental effort to hormone levels in wild birds was consistent with life-history predictions. Both BL PRL and BL CORT level in adults were positively related to nestling weight at early ...


Migration Dynamics Of The Northern Saw-Whet Owl In The Piedmont, Mountain, And Coastal Plain Provinces Of Virginia, Kyle E. Van Althuis Oct 2009

Migration Dynamics Of The Northern Saw-Whet Owl In The Piedmont, Mountain, And Coastal Plain Provinces Of Virginia, Kyle E. Van Althuis

Senior Honors Theses

The Northern Saw-whet Owl (Aegolius acadicus) is a small common owl of which little is known. The saw-whet’s migration dynamics are particularly shrouded in mystery due to the secretive nature of this owl. This study examined data obtained by capturing owls with mist nets in order to better understand volume, timing, sex differences and age differences in migration in the Piedmont province of Virginia for 2002-2007. Comparative owl capture data from two other physiographic regions (Mountain and Coastal Plain) were also examined.

Migration flight volume was highest in the Mountain province and lowest in the Coastal Plain, while movements ...

Encomium: Rolliin Harold Baker: 1916-2007, Carleton J. Phillips, Robert J. Baker, Hugh H. Genoways

Mammalogy Papers: University of Nebraska State Museum

Rollin H. Baker passed away on November 12, 2007, one day after reaching his 91st birthday. Rollin was a living legend, famous for his pioneering research on biogeography and natural history of Mexican mammals, especially rodents, for his contributions to the understanding of Michigan mammals, and for being a mentor and friend to all young, aspiring mammalogists. Rollin Baker’s career lasted way beyond his traditional retirement, and in his final months he was still active in the Texas Society of Mammalogists and in conservation issues in Texas. Indeed, when he was 89 years old he presented a guest lecture ...


Life History, Sexual Dimorphism And 'Ornamental' Feathers In The Mesozoic Bird Confuciusornis Sanctus., Winfried S. Peters, Dieter Stefan Peters Sep 2009

Life History, Sexual Dimorphism And 'Ornamental' Feathers In The Mesozoic Bird Confuciusornis Sanctus., Winfried S. Peters, Dieter Stefan Peters

Winfried S. Peters

The life history of Confuciusornis sanctus is controversial. Recently, the species’ body size spectrum was claimed to contradict osteohistological evidence for a rapid, bird-like development. Moreover, sexual size dimorphism was rejected as an explanation for the observed bimodal size distribution since the presence of elongated rectrices, an assumed ‘male’ trait, was uncorrelated with size. However, this interpretation (i) fails to explain the size spectrum of C. sanctus which is trimodal rather than bimodal, (ii) requires implausible neonate masses and (iii) is not supported by analogy with sexual dimorphisms in modern birds, in which elongated central rectrices are mostly sex-independent. Available ...


Summer Field Report, June-July 2009, W. Ross Silcock Sep 2009

Summer Field Report, June-July 2009, W. Ross Silcock

Nebraska Bird Review

This was an interesting summer, with range expansions of multiple species continuing in all directions, but predominantly northward. Exceptions to the northward trend were Trumpeter Swan, which bred south of its usual western Sandhills range, and Sedge Wren, which may be occurring in June in northeast Nebraska in greater numbers. Moving eastward are Western Wood-Pewee, which now overlaps with westward-moving Eastern Wood-Pewee in Lincoln Co, Cordilleran Flycatcher in the Pine Ridge, and Lesser Goldfinch in the west. Song Sparrow is also expanding south and west. No fewer than 16 species are moving north and/or northwestward. Several species were seen ...

Long-Tailed Jaegers In Western Nebraska, Stephen J. Dinsmore Sep 2009

Long-Tailed Jaegers In Western Nebraska, Stephen J. Dinsmore

Nebraska Bird Review

The Long-tailed Jaeger is an accidental migrant in Nebraska with just one accepted record through the mid-1990s. Based on records from adjacent states, especially Colorado (Andrews and Righter 1992) and Wyoming (Faulkner 2010), the species is probably more frequent than these records indicate, and its status is further complicated by possible confusion with Pomarine and Parasitic jaegers. In this article I report details of four records of Long-tailed Jaegers in western Nebraska and comment on the species' identification and status in the state.
