Helicobacter pylori colonizes 50% of the world’s population, whereby glycoproteins and Lewis Y-containing lipopolysaccharides contribute to its pathogenesis. We investigated whether the HopE porin is glycosylated, if the glycan is Lewis Y, and if this is mediated by the putative oligosaccharide transferase HP0946 or the O-antigen ligase WaaL. Western blotting was performed on outer membranes with anti-HopE antibodies, anti-Lewis Y antibodies and fucose-binding BambL lectin to ascertain HopE glycosylation. We discovered that HopE is likely glycosylated by a non-Lewis Y fucose-containing glycan and neither HP0946 nor WaaL are the transferase. Additionally, we investigated HopE’s role in antibiotic susceptibility via Etest …

The Inhibitory Effects Of A Novel Gel On Staphylococcus Aureus Biofilms, Lindsey Vance
Undergraduate Honors Theses
Antibiotic resistance is an ever-growing topic of concern within the medical field causing researchers to examine the mechanisms of resistance to develop new antimicrobials. Bacteria’s ability to form biofilms is one mechanism which aids in antimicrobial resistance. Staphylococcus aureus is of special interest as it is one of the most frequent biofilm-forming bacteria found on medical devices causing infections and posing dangerous threats in a clinical setting. A recently developed antimicrobial gel has been shown to have profound effects on treating bacterial infections and wound healing. This research is centered upon examining the antimicrobial effects of this gel on the …
