Cultivation-Dependent Analysis Of Microorganisms Associated With Various Hydraulic Fracturing Fluids, Anthony Harrington
Cultivation-Dependent Analysis Of Microorganisms Associated With Various Hydraulic Fracturing Fluids, Anthony Harrington
UNLV Theses, Dissertations, Professional Papers, and Capstones
The overarching goal of this study is to gain more insight to the microbial interactions associated with hydraulic fracturing by studying the culturable microorganisms present in various types of hydraulic fracturing fluids. Extraction of natural gas and other unconventional resources using hydraulic fracturing has increased in the last decade and very few studies have been conducted on the microorganisms associated with the various water types used in the process. From the very few published studies, the only cultivation-dependent method used involved determining the most probable number (MPN) of various metabolic groups, however the researchers failed to ask more in-depth questions …
The Effects Of Honeybee (Apis Mellifera) Antimicrobial Peptides On Paenibacillus Larvae, Jasmin Camille Khilnani
The Effects Of Honeybee (Apis Mellifera) Antimicrobial Peptides On Paenibacillus Larvae, Jasmin Camille Khilnani
UNLV Theses, Dissertations, Professional Papers, and Capstones
American Foulbrood Disease (AFB) is the most detrimental bacterial disease that affects honeybee larvae (Apis mellifera) worldwide. The etiological agent of AFB is the Gram-positive, spore-forming bacterial pathogen, Paenibacillus larvae. Treatment with antibiotics, specifically oxytetracycline, has led to the development of antibiotic resistance in P. larvae. Therefore, there is a pressing need for an alternative treatment method. The overall goal of this project was to test naturally occurring, active antimicrobial peptides (AMPs), which are produced in the adult honeybee, against vegetative P. larvae. These active AMPs could potentially be used as a prophylactic treatment to prevent P. larvae infection of …
Alternate Germinants Of C. Difficile, A Leading Hospital Pathogen, Sean Tanzey, Ernesto Abel-Santos
Alternate Germinants Of C. Difficile, A Leading Hospital Pathogen, Sean Tanzey, Ernesto Abel-Santos
McNair Poster Presentations
Clostridium difficile infections (CDI) are the leading nosocomial infections worldwide. Humans are asymptomatic carriers of C. difficile spores in the intestinal tract. The process known as germination occurs when otherwise harmless C. difficile spores are converted to toxin-producing cells upon recognition of bile salts in humans. This distinctive transition ultimately leads to the onset of disease and recurrent CDI. Germination profiles will be characterized in response to peptidoglycan (PG) fragments isolated from various bacterial species. These specific peptidoglycan fragments contain different amino acid residues that may induce different germination responses. Purification and structural determination of the peptidoglycan fragments will be …
