The Potential For Dickeya Dianthicola To Be Vectored By Two Common Insect Pests Of Potatoes, Jonas K. Insinga
The Potential For Dickeya Dianthicola To Be Vectored By Two Common Insect Pests Of Potatoes, Jonas K. Insinga
Electronic Theses and Dissertations
Dickeya dianthicola (Samson) causing blackleg and soft rot was first detected in potatoes grown in Maine in 2014. Previous work has suggested that insects, particularly aphids, may be able to vector bacteria in this genus between plants, but no conclusive work has been done to confirm this theory. In order to determine whether insect-mediated transmission is likely to occur in potato fields, two model potato pests common in Maine were used: the Colorado potato beetle (Leptinotarsa decimlineata Say) and the green peach aphids (Myzus persicae Sulzer). Olfactometry and recruitment experiments evaluated if either insect discriminates between infected and …

Lead [Pb(II)] biosorption capacities of immobilized Talaromyces macrosporus on Moringa oleifera L. wood were compared against pure fungal and pure M. oleifera biomass. A Pb(II) contact test of 1000 ug/mL show similar Pb(II) removal of non-immobilized fungal biomass (F) and powdered wood colonized with fungi (WP+F), with WP+F producing more biomass. Powdered sorbents had higher Pb(II) uptake compared to whole sorbents analyzed through ICP-AES, possibly due to increased surface area for Pb(II) binding. FTIR analysis of the F, WP, and WP+F identified hydroxyl, amino, carbonyl, and sulfhydryl functional groups which constitute probable Pb(II)-affinitive binding sites. The biosorbents tested in a …

Orthohantaviruses are tightly linked to the ecology and evolutionary history of their mammalian hosts. We hypothesized that in regions with dramatic climate shifts throughout the Quaternary, orthohantavirus diversity and evolution are shaped by dynamic host responses to environmental change through processes such as host isolation, host switching, and reassortment. Jemez Springs virus (JMSV), an orthohantavirus harbored by the dusky shrew (Sorex monticola) and five close relatives distributed widely in western North America, was used to test this hypothesis. Total RNAs, extracted from liver or lung tissue from 164 shrews collected from western North America during 1983–2007, were analyzed for orthohantavirus …
A Rapid Viability And Drug‑Susceptibility Assay Utilizing Mycobacteriophage As An Indicator Of Drug Susceptibilities Of Anti‑Tb Drugs Against Mycobacterium Smegmatis Mc2 155, Gillian Catherine Crowley, Jim O'Mahony, Aidan Coffey, Riona G. Sayers, Paul D. Cotter
A Rapid Viability And Drug‑Susceptibility Assay Utilizing Mycobacteriophage As An Indicator Of Drug Susceptibilities Of Anti‑Tb Drugs Against Mycobacterium Smegmatis Mc2 155, Gillian Catherine Crowley, Jim O'Mahony, Aidan Coffey, Riona G. Sayers, Paul D. Cotter
Department of Biological Sciences Publications
Background: A rapid in-house TM4 mycobacteriophage-based assay, to identify multidrug resistance against various anti-tuberculosis drugs, using the fast-growing Mycobacterium smegmatis mc2 155 in a microtiter plate format was evaluated, based on phage viability assays. Methods: A variety of parameters were optimized before the study including the minimum incubation time for the drugs, phage and M. smegmatis mc2 155 to be in contact. An increase in phage numbers over 2 h was indicative that M. smegmatis mc2 155 is resistant to the drugs under investigation, however when phage numbers remained static, M. smegmatis mc2 155 found to …
Crispr/Cas9 In Yeast: A Multi-Week Laboratory Exercise For Undergraduate Students, Randi J. Ulbricht
Crispr/Cas9 In Yeast: A Multi-Week Laboratory Exercise For Undergraduate Students, Randi J. Ulbricht
Open Educational Resources
Providing undergraduate life-science students with a course-based research experience that utilizes cutting-edge technology, is tractable for students, and is manageable as an instructor is a challenge. Here, I describe a multi-week lesson plan for a laboratory-based course with the goal of editing the genome of budding yeast, Saccharomyces cerevisiae. Students apply knowledge regarding advanced topics such as: CRISPR/Cas9 gene editing, DNA repair, genetics, and cloning. The lesson requires students to master skills such as bioinformatics analysis, restriction enzyme digestion, ligation, basic microbiology skills, polymerase chain reaction, and plasmid purification. Instructors are led through the technical aspects of the protocols, …
The Association Between Herpes Simplex Virus Type 1 Reactivation And Alzheimer’S Disease, Andrew Allee
The Association Between Herpes Simplex Virus Type 1 Reactivation And Alzheimer’S Disease, Andrew Allee
BIO 410 Spring 2019 Research Papers
This review will focus on the interaction of herpes simplex virus type 1 (HSV-1) and its causative role in pathogenesis of Alzheimer’s disease (AD) noting specifically, the epidemiological relevance of addressing this problem, as well as the molecular pathways associated. HSV-1 reactivation tends to be one of the primary causative events that is responsible for many of the pathologies associated with AD, such as: amyloid beta (Aβ) accumulation caused by malfunctioning cleavage of amyloid precursor protein (APP) as well as tau hyperphosphorylation. HSV-1 reactivation is a primary causative event in downstream dysfunction and is also shown to be directed by …
Comparison Of Immunohistochemistry Methods For Visualization Of Middle Eastern Respiratory Viral Antigen, Elena Carlos
Comparison Of Immunohistochemistry Methods For Visualization Of Middle Eastern Respiratory Viral Antigen, Elena Carlos
Kansas State University Undergraduate Research Conference
Middle Eastern respiratory syndrome (MERS), caused by MERS coronavirus (MERS-CoV) first appeared in Saudi Arabia in 2012. Although there have been less than 2,400 cases reported, the case fatality rate is 35%. Dromedary camels are the known host animal for the virus. However, they are difficult to manage experimental animals. In a recent study, alpacas proved to be a suitable experimental animal to further characterize MERS-CoV infection. Our work is part of a wider project focused on studying the efficacy of MERS-CoV antigen and RNA labeling in infected alpaca tissues, when these tissues are preserved in novel modular alcohol fixatives …
The Effects Of Bacterial Endotoxin Lps On Synaptic Transmission At The Neuromuscular Junction, Robin L. Cooper, Micaiah Mcnabb, Jeremy Nadolski
The Effects Of Bacterial Endotoxin Lps On Synaptic Transmission At The Neuromuscular Junction, Robin L. Cooper, Micaiah Mcnabb, Jeremy Nadolski
Biology Faculty Publications
The direct action of bacterial lipopolysaccharides (LPS) endotoxin was shown to enhance synaptic transmission and hyperpolarize the membrane potential at low doses, but block glutamatergic receptors and decrease observable spontaneous events at a high dosage. The dosage effects are LPS type specific. The hyperpolarization is not due to voltage-gated potassium channels or to activation of nitric oxide synthase (NOS). The effects are induced directly by LPS, independent of an immune response.
The Role Of The Igf-1/Akt/Mtor Pathway On Tibialis Anterior Muscle Hypertrophy During Regeneration In Cardiotoxin-Induced Injury In Adult Mice, Cambria Kasten, Jung A. Kim Phd
The Role Of The Igf-1/Akt/Mtor Pathway On Tibialis Anterior Muscle Hypertrophy During Regeneration In Cardiotoxin-Induced Injury In Adult Mice, Cambria Kasten, Jung A. Kim Phd
Summer Research
The purpose of this study was to determine the expression of genes in the IGF-1-mediated pathway involved in protein synthesis and degradation on muscle regeneration after cardiotoxin (CTX)-induced injury, which may be causing muscle hypertrophy. Quantitative Real-Time Polymerase Chain Reaction (qPCR) and western blots were used to quantify expression of degradation and synthesis markers respectively. Absolute and relative tibialis anterior (TA) muscle weights were significantly greater than the respective control after 2-, 3-, and 4-weeks CTX. There were no significant differences in gene expression of atrogin-1, MuRF-1, or myostatin between the CTX-injured and the Control TA muscle at the 2-, …
