Surveillance And Comparative Genomics Of Bacteria From Hospital And Human Reservoirs, Emily E. Benedict Dec 2026

Surveillance And Comparative Genomics Of Bacteria From Hospital And Human Reservoirs, Emily E. Benedict

WUSM Theses and Dissertations – All Programs

Bacteria are diverse and adaptable and, consequently, present in a wide variety of environments. They are capable of growing under intense pressures, including those brought on by the human immune system and disinfection strategies. To survive these pressures, bacteria develop resistances. Antimicrobial resistance, which occurs when a microbe is no longer responsive to the antibiotic intended to control it, is one such adaptation that presents an especially serious threat, as it limits treatment options for infections caused by antimicrobial resistant microbes. Similarly, the ability of bacteria to survive in environments subjected to heavy disinfection efforts, such as intensive care units …

Precision Approaches Improve Community Health, Roger A. Rennekamp, David Buys

Journal of Extension

Recent advances in data science provide Extension practitioners with access to data sorted by zip code, census tract, or neighborhood. Such hyper-local data now allows Extension personnel to assess community needs and assets at a more granular level and focus their work on the people and communities of greatest need. In this article, we introduce an approach we refer to as precision public health. Using such a precision approach to community assessment and, ultimately, programming can save money, increase the likelihood of producing measurable results, and create more manageable workloads for county-based Extension personnel.
