OverviewAI-generated summary

Ohgew Kweon's research focuses on the identification and characterization of bacteria, particularly in the context of pharmaceutical products and health-related infections. Kweon has investigated methods for detecting viable bacteria, including the development of Propidium Monoazide (PMAxx)-based assays combined with droplet digital PCR (ddPCR) and recombinase polymerase amplification (RPA Exo) for the rapid detection of the Burkholderia cepacia complex in various solutions. Additional work includes the development of loop-mediated isothermal amplification (LAMP) assays for the same bacterial complex in non-sterile pharmaceutical products and flow cytometry techniques for specific detection and enumeration.

Kweon's publications also address the adaptive responses of bacteria to antimicrobial treatments, such as the dynamic response of Pseudomonas aeruginosa to antibiotic-impregnated catheters and the global quantitative proteome response of Staphylococcus epidermidis biofilms to subinhibitory tigecycline. Further research has explored the decolorization of azo dyes by phylogenetically diverse bacteria isolated from tattoo inks and the epidemiology of tattoo-associated infections.
