An investigation of the region of DNA required for Streptocymes Penemafaciens plasmid pSPN1 replication
… was constructed by inserting a streptomycin resistance gene from plasmid pIJ4642 into the ampicillin resistance gene of the vector Bluescript. The resistance gene was able to function in both E.coli and Streptomyces species and thus pBlue could serve as a vector for shortening and sequencing …

Isolation and Ecology of Bacterial Populations Involved in Reductive Dechlorination of Chlorinated Solvents
… shares common traits of Dehalococcoides such as ampicillin resistance, strict hydrogen-dependent metabolism, and a low hydrogen consumption threshold concentration. Culture-dependent and independent, 16S rRNA gene and reductive dehalogenase gene targeted PCR approaches suggested culture purity.

Insights Into Determinants That Contribute to Colonization, Virulence and Antibiotic Resistance In Enterococci
… are very difficult to treat due to multi-drug resistance. The work presented in the first part of this dissertation elucidates a mechanism for the regulation of pilus expression. I showed that ATT is the initiation codon of <em>ebpA</em>, the first gene of an operon that codes for the …

Molecular and Genomic Based Insights Into The Evolution of Enterococcus Faecium From Commensal to Hospital-Adapted Pathogen
… isolates possess virulence and antibiotic resistance determinants that are less abundant or lacking in community isolates. I also revealed that the level of ampicillin resistance increased over time in clinical strains. By sequencing the <em>pbp5</em> gene, I demonstrated an ~5% difference …

Developing a Novel Antibiotic Resistance Detection Method for Water Systems using IDEXX TECTA Technologies
… costs. Traditional methods for detecting resistance, though effective, are hindered by slow results, the need for intensive labor, specialized training, costly equipment, and a lack of portable, dependable alternatives 26. Consequently, there exists a substantial gap in our understanding …

Investigating the role of nonantibiotic chemical contaminants in the evolution of antibiotic resistance
Antibiotic resistance, the ability of bacteria to resist the effects of antibiotic drugs, has now become a global threat to public health. Every year around 700,000 people die due to the antibiotic-resistant bacterial infections, and this number is even predicted to reach as many as 10 million by …
