The Role Of Neurokinin Receptors And Satellite Glial Cells In Herpes Simplex Virus 1 Latency, Andrew Jerome Jan 2018

The Role Of Neurokinin Receptors And Satellite Glial Cells In Herpes Simplex Virus 1 Latency, Andrew Jerome

Wayne State University Dissertations

The ability of herpes simplex virus 1 (HSV-1) to establish a lifelong infection in neurons of the trigeminal ganglion (TG) make it a constant public health threat. Viral reactivation from its latent state is currently the leading cause of viral induced blindness in the United State, as well as the leading cause of herpes simplex encephalitis. Unfortunately, how the virus is able to both establish and maintain its latent state in the TG is not well understood. The purpose of this work was to better understand how neuropeptide signaling through neurokinin receptors, as well as how satellite glial cells (SGCs) …


Optimisation Of Ion Exchange Chromatography Purification Protocols For A Staphylococcal Peptidoglycan Degrading Hydrolase Enzyme, Fiona Maher Jan 2018

Optimisation Of Ion Exchange Chromatography Purification Protocols For A Staphylococcal Peptidoglycan Degrading Hydrolase Enzyme, Fiona Maher

Theses

Bacteriophage (phage) are the most abundant biological entities on earth and were first discovered by d’Herelle in 1917. They are found wherever their hosts live and, like all viruses they do not have the ability to make their own protein. Therefore, in order to reproduce, phage must invade and infect bacterial cells. This project focused on the optimisation of Ion Exchange Chromatography purification protocols for a staphylococcal peptidoglycan degrading hydrolase enzyme (CHAPk). The project objective was to obtain the greatest yield of enzyme from the growth of the E.coU XL 1-Blue expression system into which the vector pQE60 was previously …


Gene Knockout Of Prfa And The Arginine Deiminase Pathway In Listeria Monocytogenes, Kearstin Edmonds Jan 2018

Gene Knockout Of Prfa And The Arginine Deiminase Pathway In Listeria Monocytogenes, Kearstin Edmonds

Online Theses and Dissertations

Listeria monocytogenes is a Gram-positive facultative intracellular pathogen. This species is a common cause of food-borne illness outbreaks with high fatality rates. L. monocytogenes is known to produce a number of virulence factors, including enzymes and toxins, which are involved in the disease process. The arginine deiminase pathway has the ability to regulate acidic environments by converting arginine to ammonia, ornithine, and ATP. With the help of a membrane-bound antiporter, the ornithine is transported out of the cell while the ammonia is converted to ammonium. The ATP by-product can also be used with the F0F1-ATPase system to help maintain homeostasis. …

Peripheral Arterial Disease Increases The Risk Of Multidrug-Resistant Bacteria Andamputation In Diabetic Foot Infections, Pinar Aysert Yildiz, Tuğba Özdi̇l, Murat Di̇zbay, Özlem Güzel Tunçcan, Kenan Hizel

Turkish Journal of Medical Sciences

Background/aim: The aim of this study was to investigate the microbiological profile and resistance rates of diabetic foot infections (DFIs) and to determine the effect of peripheral arterial disease (PAD) on the microbiology, clinical condition, and treatment outcomes. Materials and methods: Characteristics, laboratory and imaging data, and the treatment modalities of patients admitted to our hospital with a diagnosis of DFI (PEDIS classification 3-4) during 2005-2016 were analyzed according to the presence of PAD. Results: Of 112 patients who were included in this study, 86 (76.8%) had PAD. Patients with PAD were older and had higher amputation rates (P < 0.05). A microbiological profile of patients revealed a predominance of gram-positive bacteria (57.1%). Staphylococcus aureus and Streptococcus spp. were the most frequently encountered bacteria. Incidence of Pseudomonas spp. infection was higher in the PAD group (P < 0.05). Of all patients, 24.1% had multidrug-resistant (MDR) microorganisms in their wound cultures. Presence of MDR bacteria in patients with PAD was 4.9-fold higher than that in patients without PAD (P < 0.05). Conclusion: This retrospective study indicates that PAD has a significant role, especially in elderly patients with DFIs. Patients should be promptly evaluated and treated for PAD to prevent infections with resistant microorganisms and limb loss.

Human onchocerciasis - commonly known as river blindness - is one of the most devastating yet neglected tropical diseases, leaving many millions in sub-Saharan Africa blind and/or with chronic disabilities. Attempts to eliminate onchocerciasis, primarily through the mass drug administration of ivermectin, remains challenging and has been heightened by the recent news that drug-resistant parasites are developing in some populations after years of drug treatment. Needed, and needed now, in the fight to eliminate onchocerciasis are new tools, such as preventive and therapeutic vaccines. This review summarizes the progress made to advance the onchocerciasis vaccine from the research laboratory into …

Subtype C HIV-1 is responsible for the largest proportion of people living with HIV-1 infection. However, there is limited information about the roles of the brain and its cell types as a potential sanctuary for this subtype and how the sanctuary may be affected by the administration of anti-retroviral therapy (ART). To address this issue, we collected postmortem brain tissues from ART treated HIV-1 infected Zambian individuals who experienced complete viral suppression and those who did not. Tissues from various brain compartments were collected from each individual as frozen and formalin-fixed paraffin embedded brain specimens, for detection and quantification of …
