As antibiotic resistant bacterial strains are becoming more prevalent in healthcare settings, it is necessary to find alternative methods of detecting and treating these infections. One of the antibiotic resistant strains of interest is the carbapenem-resistant Enterobacteriaceae (CRE). CREs have the ability to evade some of the most potent antibiotics currently in use and employ carbapenemases to negate the effect of antibiotics. The three most common carbapenemase genes, found in carbapenem-resistant Enterobacteriaceae along with a gene found only in Escherichia coli were chosen to create a qPCR assay for rapid detection of resistant infections. The carbapenemase genes are KPC, VIM and NDM and the E. coli gene is uidA, a β-glucuronidase gene. Consensus sequences were obtained from each of the genes to account for the many variants of each gene. We were able to triplex the assay and test it against a library for twenty isolates varying by which gene they contain. Additional research has been conducted on the library of carbapenem-resistant Enterobacteriaceae using bacteriophages or phage. The Phage Hunters class isolated and identified twenty phage that infect K. pneumoniae. Out of the twenty phage, seven phage were able to effectively infect carbapenem-resistant K. pneumoniae.
