Evaluation of Field Pea Varieties for Resistance to Fusarium Root Rot Pathogens
(North Dakota State University, 2017)
Fusarium root rot is one of the most important diseases of pulse crops, with numerous Fusarium spp. comprising the disease complex. Fusarium solani and F. avenaceum have been reported to be major pathogens in the pea root ...
Ellucidation of RPG4/RPG5-Mediated Resistance Against Wheat Stem Rust in Barley
(North Dakota State University, 2015)
Wheat stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), is a major threat to barley and caused devastating reductions in yield and economic losses. The barley line Q21861 was identified as the best source of ...
Characteristics and Host Range of a Novel Fusarium Species Causing Yellowing Decline of Sugarbeet
(North Dakota State University, 2013)
In 2008, a novel and distinct Fusarium species was reported in west central Minnesota causing early-season yellowing and severe decline of sugarbeet. This study was conducted to (i) establish optimum conditions for fungal ...
16S Ribosomal RNA and Phylograms: Characterizing Student Reasoning to Learning Outcomes from the American Society for Microbiology Curriculum
(North Dakota State University, 2017)
The American Society for Microbiology (ASM) has established a suggested curriculum for introductory microbiology courses that includes a focus on evolution. However, no data is published to describe how proficiently students ...
Lung Mucosal Response to Repeated Inhalational Insults with Immunomodulatory Agents in a Murine Model of Fungal Asthma: Airway Epithelium Takes the Center Stage
(North Dakota State University, 2013)
Asthma is a debilitating disease of the lungs affecting 235 million people worldwide. Fungus-associated asthma leads to a particularly severe type of disease, and exposure to environmental fungi and their products is ...
Phenotypic and Genotypic Effects of FlhC Mediated Gene Regulation in Escherichia Coli O157:H7
(North Dakota State University, 2011)
Escherichia coli (E.coli) 0157:H7, a pathogen belonging to the enterohemorrhagic group of E.coli, has long been a concern to human health. The pathogen causes a myriad of symptoms in humans, ranging from diarrhea and malaise ...
Attachment and Biofilm Formation of Foodborne Pathogens
(North Dakota State University, 2017)
Outbreaks of Listeria monocytogenes, Salmonella, and Escherichia coli are increasingly attributed to fresh produce. Current control measures have been assessed for decades, with no alternatives adopted. Sources were ...
Efficacy of Chlorine Dioxide Fumigation on the Spores of Paenibacillus larvae, the Causative Agent of American Foulbrood Disease in Honeybees
(North Dakota State University, 2019)
Honeybees (Apis mellifera) play a critical role in agricultural pollination. However, their health and numbers are in decline. A major cause of this decline is bacterial diseases, of which American foulbrood disease (AFB) ...
Gene Regulation in Biofilms
(North Dakota State University, 2011)
Sessile bacterial communities which form on the solid surface or solid-liquid interface
are known as biofilms. Both single species and multispecies biofilms are characterized
by an extracellular matrix of polymeric ...
Physical and Chemical Treatments for Bacterial Biofilms
(North Dakota State University, 2014)
Physical and chemical treatments have been investigated for the treatment to remove biofilms. This thesis examines the problem of the removal and prevention of biofilms by: (i) using a water jet to determine biofilm stability ...
